Many of the original scientific papers have been lost to public record.
This blog is an effort to find these papers so we can seek truth from facts.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.comBlogger23125tag:blogger.com,1999:blog-4744905985737564278.post-6296338239890529252008-12-31T18:58:00.000-08:002014-08-07T04:56:42.228-07:00Artemisinin 青蒿素<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhC22l9K4J8nrH-i4MDm7sKBJhK_41-MzSWeNr_ss63GqZqf0xO-gHI9X9-B0ECC7vGkCL0R5Y7daP6LjoxcCEACE7_CGKrRRWiRjIVl2HZ2wT7z5czb7GHNwxxFhkywDF6mXkK6zifb1Ff/s1600-h/img046.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhC22l9K4J8nrH-i4MDm7sKBJhK_41-MzSWeNr_ss63GqZqf0xO-gHI9X9-B0ECC7vGkCL0R5Y7daP6LjoxcCEACE7_CGKrRRWiRjIVl2HZ2wT7z5czb7GHNwxxFhkywDF6mXkK6zifb1Ff/s400/img046.jpg" id="BLOGGER_PHOTO_ID_5195973986752505122" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a>This first scientific paper is a real bombshell. The drug was not discovered in China at all, but by a Yugoslav chemist called <a href="http://www.sanu.ac.yu/Eng/members/OdHBClan.htm">Milutin Stefanovic</a>. His name has been in the frame for a few years, but no one seems to have bothered chasing him up, so that's what I did. He's now a very old man in his 80s who lives in retirement in Belgrade, and unfortunately I couldn't speak to him in person.<br />
<br />
But a former student of his, <a href="http://helix.chem.bg.ac.yu/cgi-bin/osoblje.py?ime=BSolaja&lang=lat&sctn=organska">Bogdan Solaja</a>, who is now a Professor of Chemistry at the University of Belgrade, kindly sent me an original scientific abstract, published in 1972, which I think confirms that Stefanovic discovered the drug before the Chinese. Stefanovic didn't know it could cure malaria, and I think he probably studied it because of Soviet claims about the antibacterial properties of a herb called <span style="font-style: italic;">Artemisia annua</span>. <span style="font-style: italic;">A. annua</span> contains artemisinin in quite large amounts.<br />
<br />
But that's not the point here, so I give you a scanned version of the original abstract, presented at the Eighth International Symposium on the Chemistry of Natural Products, held in New Delhi, India, 6-12 February 1972.<br />
<br />
Stefanovic got the chemical structure a little wrong, but in my opinion he's describing artemisinin. How this relates to the Chinese discovery of the drug, well that's something I'll be discussing over the coming months.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com1tag:blogger.com,1999:blog-4744905985737564278.post-26506766795499427002008-12-01T03:23:00.000-08:002014-08-07T04:47:01.756-07:00Milutin Stefanovic and Artemisinin 青蒿素<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkUZwibViEkYMiSpVQWdHDmU_Hr1Xmkgjn7wzcLkxWOFkuQNteziS8awfSTybpIjXvascvpIxwb-Uji9zpX-X6NgOaQ5NA9KnPgURzGIZkxG9Gw-s6QvCJonNVIvmMWNkr9QXfgyxBuzgD/s1600-h/img051.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkUZwibViEkYMiSpVQWdHDmU_Hr1Xmkgjn7wzcLkxWOFkuQNteziS8awfSTybpIjXvascvpIxwb-Uji9zpX-X6NgOaQ5NA9KnPgURzGIZkxG9Gw-s6QvCJonNVIvmMWNkr9QXfgyxBuzgD/s400/img051.jpg" id="BLOGGER_PHOTO_ID_5196100168596694322" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a><br />
The next artemisinin reference I've found came out in 1975. In a short note submitted to the journal <span style="font-style: italic;">Phytochemistry</span> on 6 February 1975 and published later that year, Stefanovic mentions a chemical he calls "arteannuin A". The note itself is, unfortunately, not about arteannuin A, but another, unrelated, chemical found in <span style="font-style: italic;">Artemisia annua</span>.<br />
<br />
But what's interesting is the reference attached to the arteannuin A, which I've scanned here. The first part cites the <a href="http://panyutiger.blogspot.com/2008/05/artemisinin.html">New Delhi abstract</a>. The second part is more tantalizing: "full experimental data will be published soon." Alas, Stefanovic never published that data. In my view, a mistake of historic proportions because of course "arteannuin A" is artemisinin.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com1tag:blogger.com,1999:blog-4744905985737564278.post-46685677835743240002008-11-30T18:33:00.000-08:002014-08-07T04:47:24.182-07:00Into China in search of Artemisinin 青蒿素<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhEKC7wnIj7IemweSw26LiPVmHuV9urhgxelHquC2OV4hykYEjd8vGP4MsxfwThw2IQK3Gukq3e069jw0ygCNWFs6ipDW26C8KV-_zC8Sfl-i9bPHUMgkRoEEKsHdGBBo6d-8PpplAEC4dZ/s1600-h/img047.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhEKC7wnIj7IemweSw26LiPVmHuV9urhgxelHquC2OV4hykYEjd8vGP4MsxfwThw2IQK3Gukq3e069jw0ygCNWFs6ipDW26C8KV-_zC8Sfl-i9bPHUMgkRoEEKsHdGBBo6d-8PpplAEC4dZ/s400/img047.jpg" id="BLOGGER_PHOTO_ID_5196712257270949186" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a><br />
We finally reach China, after beginning our journey in <a href="http://panyutiger.blogspot.com/2008/05/artemisinin.html">Belgrade</a>. This is the first scientific article to report on Chinese artemisinin research. It appeared in the journal <span style="font-style: italic;">Ke Xue Tong Bao</span> <a href="http://csb.scichina.com/cn/dqml.asp">科學通報</a> in 1977. According to a footnote printed at the bottom of the article itself, it was received at the journal on 20 February 1976.<br />
<br />
It's a one page article and I reproduce a picture of the page here. The title reads: "A new type of sesquiterpene lactone - <span style="font-style: italic;">qinghaosu</span>". The body texts starts with the words: "We isolated a type of crystal from <span style="font-style: italic;">Artemisia annua</span>. It was given the name <span style="font-style: italic;">qinghaosu</span>." Then we get a mass of technical details about melting points and infrared, proton and C-13 spectra, that, frankly, would only be comprehensible to a physical chemist and certainly aren't comprehensible to me.<br />
<br />
But I think a few things are still worth noting. First, the Chinese refer to the molecule as <span style="font-style: italic;">qinghaosu</span> 青蒿素. They abandon <a href="http://panyutiger.blogspot.com/2008/05/milutin-stefanovic-and-artemisinin.html">Stefanovic's "arteannuin A" terminology</a>, and they also don't cite Stefanovic, or anyone else, because the paper lacks references.<br />
<br />
Second, the paper goes out under an anoymous authorship, namely: "Coordinating Group for Research on the Structure of <span style="font-style: italic;">Qinghaosu</span>". There's no information whatsoever about who might be part of this group, or even how many members there are.<br />
<br />
Third, <a href="http://panyutiger.blogspot.com/2008/05/artemisinin.html">unlike Stefanovic</a>, I think the Chinese get the chemical structure correct. I would, however, appreciate the views of a proper organic chemist on this conclusion.<br />
<br />
But there is something more. Unbelievably, they don't mention malaria! Essentially, they avoid telling us just about the most interesting feature of the molecule: that it can cure malaria. This is such a curious omission that it raises all sorts of interesting questions that I will discuss in future posts.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-75392452529224613662008-11-01T03:02:00.000-07:002014-08-07T04:47:45.091-07:00Artemisinin, 1979<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhYCLCBurqVcMNTifDTj0DSj-tga4d4CFJ-Vc4WjC8gEfr27qCtBsOO0zaf3dMoDUFArI9q-bawIKrSojgI9nM3R8RISLYz_NFoGRrY_On8_J6uwBRBRizlKlLyKMlyKPy0D3d0GSjmJGyq/s1600-h/img048.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhYCLCBurqVcMNTifDTj0DSj-tga4d4CFJ-Vc4WjC8gEfr27qCtBsOO0zaf3dMoDUFArI9q-bawIKrSojgI9nM3R8RISLYz_NFoGRrY_On8_J6uwBRBRizlKlLyKMlyKPy0D3d0GSjmJGyq/s400/img048.jpg" id="BLOGGER_PHOTO_ID_5197213952400794962" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a><br />
This is the big year - 1979 - when the Chinese announce their artemisinin discovery in detail, two years after the first <a href="http://panyutiger.blogspot.com/2008/05/into-china-in-search-of-artemisinin.html">brief report</a>. And it starts in May 1979, exactly 29 years ago this month, with a paper in the journal <span style="font-style: italic;">Hua Xue Xue Bao</span> <a href="http://sioc-journal.cn/hxxb/cn/gywm_zzjs.asp">化學學報</a>. It's quite a long paper, 10+ pages, so I only reproduce the first page.<br />
<br />
There's a lot to discuss here, but I first want to point out that the authors submitted the article to the journal on 3 April 1978, a full year before it was actually published.<br />
<br />
For the first time we have some actual Chinese names. They are: Liu Jing-ming, Ni Mu-yun, Fan Ju-fen and Tu You-you, at the Institute of Chinese Materia Medica, Academy of Chinese Traditional Medicine, Peking; and Wu Zhao-hua, Wu Yu-lin and Chou Wei-shan, at the Institute of Organic Chemistry, Academia Sinica, Shanghai. Here I'm using the original English transliterations that accompanied the paper back in 1979 (it was before the widespread use of pinyin).<br />
<br />
So we can clearly say who the key players were. According to the standard format, where the leaders of the research go last in the lists of authors, they are: Tu You-you <a href="http://www.winpharm.net/Article/ShowArticle.asp?ArticleID=693">屠呦呦</a> and Chou Wei-shan <a href="http://www.cst.sh.cn/ys/english/hxb/zhouwsh11.htm">周維善</a>. Mark those names well, because it gets more complicated. I'm going to discuss these complications in later posts.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-80685514801176359072008-10-31T17:36:00.000-07:002014-08-07T04:48:08.161-07:00A Detailed Chronological Record of Project 523 and the Discovery and Development of Qinghaosu (Artemisinin)I've been meaning to post this up for some time, so it's a bit out of date. This is the book published in 2006 that gives a historical overview of the artemisinin discovery, from the Chinese perspective.<br />
<br />
Here's the citation:<br />
張劍方. 遲到的報告五二三項目與青蒿素研發紀實. 羊城晚報出版社, 2006.<br />
Zhang Jianfang. <span style="font-style: italic;">A Detailed Chronological Record of Project 523 and the Discovery and Development of Qinghaosu (Artemisinin)</span>. Yangcheng Evening News Publisher, 2006.<br />
<br />
Zhang Jianfang, who edited the volume, directed the artermisinin project back in the 1960s, and the book is a good start on mapping the details of the discovery. But I think it's vital the Chinese make even greater efforts to record the oral history of the discovery - and do it now, rather than waiting. If I understand it right, one of the leading project workers from the 1960s/70s, Professor Zhou Keding <a href="http://www.youtube.com/watch?v=WsH-o7R71hQ">周克鼎</a>, sadly died of old age a few months ago.<br />
<br />
Another unfortunate problem is that the book isn't available online, and of course it's in Chinese. There is an English translation, but a Chinese publisher apparently backed out of printing it because he couldn't read English and worried the translation might say something that would upset the censor.<br />
<br />
<a href="http://sunzi1.lib.hku.hk/hkjo/view/21/2100772.pdf">Dr Keith Arnold</a> - the first Western scientist to hear about artemisinin when he visited Guangzhou in 1979 - kindly gave me the unpublished English version of the first two chapters back in 2007, but as far as I know the full translation hasn't yet found a publisher. Arnold's wife, Dr Muoi Arnold, did the translation.<br />
<br />
There was talk at the time of posting the English version online, but I don't think this has happened. The <span style="font-style: italic;">British Medical Journal</span> commissioned me to write an article on the book, but in the end they didn't publish it, so the story sank without trace.<br />
<br />
For those wanting to know more, the only online information I can find on the book is the publisher's site, <a href="http://www.ycwb.com/ycwb/2007-01/05/content_1339932.htm">Yangcheng Evening News</a>. I do wonder if you can order the book from Chinese Amazon, or similar (I haven't checked because I already own a copy).William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-49983973025147368542008-10-01T23:59:00.000-07:002014-08-07T04:36:24.911-07:00Further progress along the road to integrating Chinese and Western medicine...<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5r5NrHx_mSSp03k8XIn7_cUdDicklM-j24xmXGqk1pJI9MgYjAOxcBaoNXsVp_3XMm5ZvGZQg6sois0oBvSUFsxdN4KGNfWhRPW2oyw-ceZlMJ8bCACCr6qf1vEYajHaVgO8kNhOSXZQ/s1600-h/img319-5_2.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5r5NrHx_mSSp03k8XIn7_cUdDicklM-j24xmXGqk1pJI9MgYjAOxcBaoNXsVp_3XMm5ZvGZQg6sois0oBvSUFsxdN4KGNfWhRPW2oyw-ceZlMJ8bCACCr6qf1vEYajHaVgO8kNhOSXZQ/s400/img319-5_2.jpg" id="BLOGGER_PHOTO_ID_5438750006346083026" style="cursor: hand; cursor: pointer; float: left; height: 300px; margin: 0 10px 10px 0; width: 400px;" /></a><br />
<br />
Here's a paper from January 1979 reporting on the qinghaosu discovery. It was published in the Journal of New Medicine and Pharmacology. The headline reads:<br />
<br />
在中西醫結合道路上乘勝前進-記青蒿素治疔瘧疾科研成果鑒定會<br />
<br />
In other words:<br />
<br />
Further progress along the road to integrating Chinese and Western medicine - Report of a meeting to appraise scientific research on qinghaosu as a cure for malaria<br />
<br />
In fact this is an editorial introducing a series of articles on qinghaosu. It's the earliest mention I can find of qinghaosu as a cure for malaria (as I've discussed <a href="http://qinghaosu.blogspot.com/2008/05/into-china-in-search-of-artemisinin.html">before</a>, the 1977 paper doesn't mention the malaria part).William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-26181471170638851632008-10-01T01:05:00.000-07:002014-08-07T04:49:36.174-07:00The Chinese Medical Journal paper, 1979<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiD7mHYCaT6On7bPxU6-jZ5seVbaHKm8yJaqsubMK6ozELmXmXwsYxi3hvR8Rc8LirlFjjXN2TNyWNMSjfA0njgo97zOJCkGRptg4ErX6qW_XWiepa5QIKM5VueyGHjmQg2541elnWD8XtF/s1600-h/img049.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiD7mHYCaT6On7bPxU6-jZ5seVbaHKm8yJaqsubMK6ozELmXmXwsYxi3hvR8Rc8LirlFjjXN2TNyWNMSjfA0njgo97zOJCkGRptg4ErX6qW_XWiepa5QIKM5VueyGHjmQg2541elnWD8XtF/s400/img049.jpg" id="BLOGGER_PHOTO_ID_5201626814650655282" style="cursor: pointer; float: left; margin: 0pt 10px 10px 0pt;" /></a><br />
This must be about the most famous artemisinin paper ever. It really brought the artemisinin discovery to the world's attention, not least because it was written in English.<br />
<br />
Professor Nick White, who pioneered the clinical use of artemisinin in Thailand, <a href="http://malaria.wellcome.ac.uk/doc_WTD023861.html">waxes lyrical</a> about when he first saw the paper.<br />
<br />
The Chinese published it in the December 1979 issue of the <span style="font-style: italic;"><a href="http://www.cmj.org/">Chinese Medical Journal</a></span> - again under an anonymous authorship, so we have no idea who wrote it.<br />
<br />
I'm not going to reproduce the paper here; what interests me most are the paper's references, published in Chinese. So before I get on with any more discussion, I want to post up a translation.<br />

Here I'm continuing my discussion of the famous 1979 <span style="font-style: italic;">Chinese Medical Journal</span> paper, in particular the <a href="http://panyutiger.blogspot.com/2008/05/chinese-medical-journal-paper-1979.html">references</a> on the paper.<br />
<br />
The first thing that strikes me: although the paper is entirely in English, the authors decided to keep the reference list in Chinese. To my mind, a very strange decision as the paper's intended audience, the international scientific community, can't (as a general rule) read Chinese.<br />
<br />
The second thing to note is that references 1-8 are 1950s reprints of old Chinese medical books, or <span style="font-style: italic;">materia medica</span>.<br />

At the time, Chairman Mao made a big show of promoting Chinese medicine, so Chinese publishers made a big effort to revive the old books by reprinting them. This, by the way, is an interesting story in itself, and it's been documented by the historian Kim Taylor in her book <span style="font-style: italic;"><a href="http://www.amazon.com/Chinese-Medicine-Early-Communist-1945-63/dp/041534512X">Chinese Medicine in Early Communist China, 1945-63</a></span>.<br />
<br />
References 1-8 give me an excuse to wander off into an incense-filled world of temples, scholars and Daoists, but before I do that, I want to tackle the more prosaic issues brought up by references 9-10.<br />
<br />
The question here is: why don't the authors cite the <a href="http://panyutiger.blogspot.com/2008/05/artemisinin-1979.html">1979 article</a> by 屠呦呦 and 周維善? Could it be they were not aware of this article - or did they deliberately avoid citing it?<br />
<br />
Reference 9 is, of course, the <a href="http://panyutiger.blogspot.com/2008/05/into-china-in-search-of-artemisinin.html">1977 paper</a> in 科學通報.<br />
<br />
Reference 10 I think must refer to a paper submitted to the journal <span style="font-style: italic;">Scientia Sinica</span> <a href="http://www.scichina.com/">中國科學</a> on 9 May 1978 and published in English in March 1980. I reproduce the original title and abstract of that paper here, but I'll discuss it at a later date because I'm trying to keep a roughly chronological order to these blog entries, at least in the first instance.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-13978744293775751902008-09-01T00:48:00.000-07:002014-08-07T04:50:43.637-07:00Chinese scientists and Western journalsWhy didn't the Chinese scientists publish the first qinghaosu report in a Western journal?<br />
<br />
Well, Western journals aren't the be all and end all, but I think the reason here must be that to publish in a foreign journal in the 1970s would have been viewed as treason. Anyone who did it would have been labeled a capitalist-roader or some such and dealt with very harshly.<br />
<br />
So it wasn't until March 1982 that Tu Youyou 屠呦呦 published a report on the discovery in a foreign (German) journal, <span style="font-style: italic;"><a href="http://panyutiger.blogspot.com/2008/07/qinghaosu-heads-west.html">Planta Medica</a></span>.<br />
<br />
Now, of course, there's no such reticence and Chinese scientists are positively encouraged to publish in high-impact foreign journals.

<br />
The usual explanation is that this was the time of Chairman Mao's reign of terror, so there was no place to publish because the scientific journals had been closed down. In historical research, of course, just because things happen at the same time doesn't make one the cause of the other.<br />
<br />
Go in a little closer and it gets more interesting. While the reason not to publish must surely have been the reign of terror, the reason they eventually did publish seems to have been good old academic rivalry. It's nice to know that survived in spite of everything.<br />
<br />
According to Zhang Jianfang's <a href="http://panyutiger.blogspot.com/2008/05/detailed-chronological-record-of.html">account</a>, the Chinese saw the suggestive footnote in Milutin Stefanovic's <a href="http://panyutiger.blogspot.com/2008/05/milutin-stefanovic-and-artemisinin.html">1975 paper</a>, and rushed to the presses.<br />
<br />
If we fast forward a bit, the other question that bugs me is the long lead times between the early papers being sent to the journals and the papers actually getting published:<br />
<br />
1. <a href="http://panyutiger.blogspot.com/2008/05/artemisinin-1979.html">Structure and reactions of arteannuin</a>. Submitted: 3 April 1978. Published May 1979.<br />
2. <a href="http://panyutiger.blogspot.com/2008/05/discussion-of-1979-paper-in-chinese.html">Crystal structure and absolute configuration of qinghaosu</a>. Submitted: 9 May 1978. Published: March 1980<br />
<br />
Perhaps there was a long backlog of papers because the journals had been closed down for a bit? The editor might therefore have worked through, methodically publishing submissions in chronological order, according to when they had been received. <br />
<br />
Scrupulously fair no doubt, but surely any journal editor worth his or her salt would have realized the qinghaosu papers were dynamite, and rushed them to the presses?William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-2384883403214059682008-07-31T16:25:00.000-07:002014-08-07T04:52:38.638-07:00Qinghaosu heads West<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi0U7-eG_6hL7z5GtR8iX1PjmhSl59CR2GPO_31FbqK199w0jKE3XCWO3P6mZzVtrG4dHa15I0EW7JUudtFxPvtAIDwHkKyFWyFKD79MvNgcSTs8VlgAcRQEQxrFGQdDCY3AZsiDB3ZZSIR/s1600-h/img095.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi0U7-eG_6hL7z5GtR8iX1PjmhSl59CR2GPO_31FbqK199w0jKE3XCWO3P6mZzVtrG4dHa15I0EW7JUudtFxPvtAIDwHkKyFWyFKD79MvNgcSTs8VlgAcRQEQxrFGQdDCY3AZsiDB3ZZSIR/s400/img095.jpg" id="BLOGGER_PHOTO_ID_5222681831369804738" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a><br />
I'm going to fast forward to the early 1980s and the first reports about qinghaosu published in Western scientific journals. For the moment I'm ignoring the large numbers of scientific papers published in Chinese journals that came out at the same time, which you can easily find by searching <a href="http://www.ncbi.nlm.nih.gov/sites/entrez/">PubMed</a> (don't worry, I'll return to these later).<br />
<br />
To begin, here are some highlights:<br />
<br />
March 1982<br />
Tu Youyou 屠呦呦 is the first Chinese scientist to publish a <span style="font-style: italic;">qinghaosu</span> article in a Western scientific journal.<br />

Now we are in the realms of Kremlinology, but lets proceed anyway to analyse the citations in the early Chinese papers.<br />
<br />
What puzzles me is the inconsistency of citation in the following papers (papers that I've already mentioned on this blog):<br />
<br />
1. <a href="http://panyutiger.blogspot.com/2008/05/artemisinin-1979.html">Structure and reactions of arteannuin</a>, published May 1979<br />
2. <a href="http://panyutiger.blogspot.com/2008/05/chinese-medical-journal-paper-1979.html">Antimalaria studies on qinghaosu</a>, published December 1979<br />
3. <a href="http://panyutiger.blogspot.com/2008/05/discussion-of-1979-paper-in-chinese.html">Crystal structure and absolute configuration of qinghaosu</a>, pubished March 1980<br />
<br />
What's curious is that the 1980 paper doesn't cite the 1979 papers (see picture for list of references in the 1980 paper), nor does the December 1979 paper cite the May 1979 paper. Most obviously, why doesn't the 1980 paper cite the May 1979 paper, as both are on similar topics?<br />
<br />
What could be the explanation for these inconsistencies? It seems to me there are two possibilities.<br />
<br />
First possibility: the authors of the 1980 paper - and we don't know their names because the paper went out under an anonymous byline of the Institute of Biophysics - didn't know about Tu Youyou 屠呦呦 and Zhou Weishan 周維善 and the other authors of the May 1979 paper.<br />
<br />
Second possibility: we are in much darker waters, where the authors of the 1980 paper did know about Tu and Zhou but deliberately avoided citing them.<br />
<br />
Either way, it would tend to suggest that, far from being a highly coordinated project (as it is often thought to have been), it was a bit disorganized, with different (rival?) groups publishing their results pretty much independently.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com1tag:blogger.com,1999:blog-4744905985737564278.post-5560265902007010602008-06-27T17:50:00.000-07:002014-08-07T04:53:48.469-07:00青蒿情黃花香A very interesting blog called <a href="http://blog.sina.com.cn/s/blog_523618b401009lq8.html">青蒿情黃花香</a>, in other words, "<span style="font-style: italic;">Qinghao</span> - news and views on the yellow flower", referred to me. (For those who don't know, <span style="font-style: italic;">Artemisia annua</span> sports rather pretty yellow blooms.)<br />
<br />
It's nice to know a Chinese person is reading my blog, and what's more, is interested in the history of <span style="font-style: italic;">qinghaosu</span> and what people outside China think about the discovery. <br />
<br />
青蒿情黃花香 says that my blog is "a mixture of fact and speculation", so lets get on with the facts and speculation...William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-40332146193609047352008-06-01T00:57:00.000-07:002014-08-07T04:53:31.013-07:00Who should get the Nobel Prize?I thought I'd wrap up today's discussion with this provocative question, which I'll discuss in more detail in later posts.<br />
<br />
My citation would be: For their analytical work leading to the discovery of artemisinin.<br />
<br />
Based on the record of published scientific works, two Chinese scientists should get the prize. They are: <a href="http://panyutiger.blogspot.com/2008/05/artemisinin-1979.html">Tu Youyou</a> 屠呦呦 and <a href="http://panyutiger.blogspot.com/2008/05/artemisinin-1979.html">Zhou Weishan</a> 周維善.<br />
<br />
But, as a Nobel can go to three people, I'd give the final third of the prize to <a href="http://panyutiger.blogspot.com/2008/05/artemisinin.html">Milutin Stefanovic</a>. He may not have known the chemical could cure malaria, but he beat the Chinese to the printing press.<br />
<br />
There's a precedent for this: <a href="http://www.detnews.com/specialreports/2001/michiganians/horwitz/horwitz.htm">Jerome Horwitz</a> gets the credit for developing the anti-HIV drug AZT, even though he synthesized the chemical long before HIV came on the scene. Like Stefanovic, he could never have dreamed his chemical would later help millions of people.<br />
<br />
Now let's pull these conclusions apart again and see where we get...William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com3tag:blogger.com,1999:blog-4744905985737564278.post-61433333178867332182008-05-31T18:23:00.000-07:002014-08-07T05:07:17.692-07:00Ge Hong 葛洪<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCPRFyDEmHkpIVIgzIm61DvR_q3p_szjDwfYMDMEh-TEuM81_YGdffsz9hhyphenhyphenPYNPRnxbqZOlSUHob3uOZc2l55pqdnYZGcZKkRcRrfTjMdmmtQ5T5P9p9lEb5UAQB60gq-tzqyTwr90DdE/s1600-h/img059.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjCPRFyDEmHkpIVIgzIm61DvR_q3p_szjDwfYMDMEh-TEuM81_YGdffsz9hhyphenhyphenPYNPRnxbqZOlSUHob3uOZc2l55pqdnYZGcZKkRcRrfTjMdmmtQ5T5P9p9lEb5UAQB60gq-tzqyTwr90DdE/s400/img059.jpg" id="BLOGGER_PHOTO_ID_5202270741917475426" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a><br />
My next stop is Ge Hong 葛洪, or reference number three in the <a href="http://panyutiger.blogspot.com/2008/05/chinese-medical-journal-paper-1979.html"><span style="font-style: italic;">Chinese Medical Journal</span> paper</a>.<br />
<br />
While the <a href="http://panyutiger.blogspot.com/2008/05/ma-wang-dui.html">Ma Wang Dui</a> manuscript is merely a historical curiosity, this reference is said to be directly related to the discovery.<br />
<br />
I've scanned an excerpt from an article in the magazine <span style="font-style: italic;">China Reconstructs</span> - now known as <span style="font-style: italic;"><a href="http://www.chinatoday.com/">China Today</a></span> - that was published in August 1979 and throws a little light on this part of the story.<br />
<br />
The sweet wormwood mentioned must be qinghao. In other words: <span style="font-style: italic;">Artemisia annua</span>.<br />
<br />
In those days <span style="font-style: italic;">China Reconstructs</span> was the main English-language organ of the Chinese Communist Party, and it was edited by a Western journalist called <a href="http://www.nytimes.com/2005/06/02/international/asia/02epstein.html">Israel Epstein</a> who had defected to China in the 1950s and was actually a Chinese citizen.<br />
<br />
Incidentally, the paragraph excerpted here comes from an article written by Ximen Lusha. It doesn't sound like a Chinese name, but Hubert Wang from the English Department at <span style="font-style: italic;">China Today</span> told me that Ximen Lusha was a Chinese woman. I don't have the characters for her name, so it's really difficult to find out anything about her, or even if she's still alive. I wonder if there's anyone out there on the Web who could tell us more?William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-76981998460183695912008-05-31T01:37:00.000-07:002014-08-07T04:55:11.923-07:00Ge Hong and Mount Luofu 羅浮山<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXy5pWtJdOFuTlralnTUb0TBVRUknWYjtPm30zYG_2CtOpU_NVhoqSoHsYvlVUgbYs1OaMCqGLITEIO5PMYF5Gbs-gVM2WZ2Uzu_zuzWBIVBaTsYnWVTX50_Ffic6c0IrWOu9uGrJTKWM3/s1600-h/img065.jpg" onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}"><img alt="" border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXy5pWtJdOFuTlralnTUb0TBVRUknWYjtPm30zYG_2CtOpU_NVhoqSoHsYvlVUgbYs1OaMCqGLITEIO5PMYF5Gbs-gVM2WZ2Uzu_zuzWBIVBaTsYnWVTX50_Ffic6c0IrWOu9uGrJTKWM3/s400/img065.jpg" id="BLOGGER_PHOTO_ID_5206469119161305634" style="cursor: hand; cursor: pointer; float: left; margin: 0 10px 10px 0;" /></a><br />
The story goes that in the year 331, <a href="http://panyutiger.blogspot.com/2008/05/zhou-hou-bei-ji-fang.html">Ge Hong</a> retired to Mount Luofu 羅浮山 where he lived until his death.<br />
<br />
In my ongoing <a href="http://panyutiger.blogspot.com/2008/05/chinese-medical-journal-paper-1979.html">quest</a> to track down every place even remotely connected with <span style="font-style: italic;">qinghaosu</span>, I made a stop at Mount Luofu last year.<br />
<br />
It's a couple of hours drive from Guangzhou 廣州, deep in the countryside. When I visited there was a temple, a few souvenir stalls, a fairground-style shooting range - and a stand of <span style="font-style: italic;">Artemisia annua</span>.<br />
<br />
The artemisinin maker <a href="http://www.artepharm.com/">Artepharm</a> has even sponsored a few plaques and information boards that record Ge Hong's legendary connection with the drug. They are clustered around the <span style="font-style: italic;">A. annua</span> plants.<br />

This refers to the medical manuscripts excavated from <a href="http://en.wikipedia.org/wiki/Mawangdui">Ma Wang Dui</a> 馬王堆 at <a href="http://en.wikipedia.org/wiki/Changsha">Changsha</a> 長沙 in southern China.<br />
<br />
I used to have a copy of the manuscripts, or rather Donald Harper's English translation in his book <span style="font-style: italic;"><a href="http://www.amazon.com/Chinese-Medical-Literature-Donald-Harper/dp/0710305826">Early Chinese Medical Literature</a></span>, but I seem to have lost it somewhere.<br />
<br />
If I remember rightly, there was a lot of discussion about herbs that could improve a man's sexual performance, and the best sexual positions for "approaching the inner chamber". All in all it was a rather racy read for something that's nearly two thousand years old.<br />
<br />
But the point here is that it mentions a herb called <span style="font-style: italic;">qinghao</span> 青蒿, not as a sex aid, but to treat hemorrhoids - the <a href="http://panyutiger.blogspot.com/2008/05/medical-manuscripts-from-ma-wang-dui.html">manuscript</a> advises the reader to expose his bum over a steaming concoction of the herb.<br />
<br />
It's the first mention of <span style="font-style: italic;">qinghao</span> in history, and a rather undignified one at that. But the herb is said to have been <span style="font-style: italic;"><a href="http://en.wikipedia.org/wiki/Artemisia_annua">Artemisia annua</a></span>. A stretch of the imagination perhaps, but not completely implausible.<br />
<br />
Curious about the tomb itself, I visited 長沙. The first must-see is the <a href="http://www.hnmuseum.com/hnmuseum/eng/main_index.jsp">Hunan Provincial Museum</a>, which houses the artefacts from the tomb.<br />
<br />
The second, more obscure, tourist attraction is of course the site of the tomb itself, ironically in the grounds of a hospital. Here's a picture I took of the hospital's entrance. The sign reads: 湖南省老年醫院, 湖南省馬王堆療醫院. In other words: Hunan Geriatric Hospital, <a href="http://www.hnmwdhospital.com/">Hunan Ma Wang Dui Hospital</a>.<br />
<br />
The Chinese discovered the tomb in 1971 during construction of underground wards, although having now been to the hospital myself, there weren't any underground wards that I could see.<br />
<br />
The name Ma Wang Dui literally means King Ma's Mound, but actually the tomb contained a Chinese nobleman, his wife and son and a thousand-and-one perfectly preserved artefacts. They were all sealed in giant wooden coffins that protected them from the elements.<br />
<br />
Among the artefacts, which included musical instruments, clothes, statues and furniture, the archeologists found manuscripts written in black ink on strips of bamboo and on sheets of silk, and that is where the characters 青蒿 appear for the first time.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com1tag:blogger.com,1999:blog-4744905985737564278.post-71710924525639473572008-05-19T17:15:00.000-07:002009-02-25T05:02:35.717-08:00Medical manuscripts from Ma Wang Dui 馬王堆I just stumbled across Donald Harper's <a href="http://panyutiger.blogspot.com/2008/05/ma-wang-dui.html">translation</a> of the medical manuscripts, so here is his rendering of the entry on <span style="font-style:italic;">qinghao</span>.

My final stop on this tour of references in the <a href="http://panyutiger.blogspot.com/2008/05/chinese-medical-journal-paper-1979.html">1979 Chinese Medical Journal paper</a> is <a href="http://en.wikipedia.org/wiki/Li_Shizhen">Li Shizhen</a> 李時珍, author of the famous <span style="font-style: italic;"><a href="http://en.wikipedia.org/wiki/Compendium_of_Materia_Medica">Ben Cao Gang Mu</a></span>. He lived in Qizhou <a href="http://www.qizhou.com.cn/">蘄州</a>, about 60 miles from Wuhan. I visited the town last year to see the Li Shizhen museum.<br />
<br />
Qizhou is very much China B, to use China-watcher Nicholas Bequelin's <a href="http://www.pbs.org/wgbh/pages/frontline/tankman/interviews/bequelin.html#1">terminology</a>. The old town was razed to the ground by Red Guards during the Cultural Revolution - and what replaced it isn't pretty. The streets aren't paved and there's rubbish everywhere.<br />
<br />
There's a run-down looking Li Shizhen hospital built in a pastiche Ming dynasty style. When new, it must have been quite something. But when I visited it was deserted and very grubby. It was a travesty of what a hospital should be - all the more ironic given the Li Shizhen connection. Next door there was an overgrown football stadium that hosted a forlorn medicinal herb market.<br />
<br />
On a dismal December day it was extraordinarily depressing even for a casual day-tripper like me.<br />
<br />
There obviously had been some investment once, but it had dried up. These days I doubt China's metropolitan central government is going to lift a finger to help. But I think the companies making money out of artemisinin should be able to chip in a dollar or two to help the town of Qizhou.<br />
<br />
There is always beauty, no matter how bleak. Around the town there are reed-lined lakes. Men and women wade around in the water grubbing for lotus roots that they boil with pork to make a wholesome stew. Their feet must be frozen in the icy water and their hands swollen and chapped, but I tasted some of the stew in what seemed to be the town's only functioning restaurant and it tasted good.<br />
<br />
I digress: there is large museum dedicated to the town's most famous son, Li Shizhen. It was built on the outskirts in the 1980s.William Burns 江威廉http://www.blogger.com/profile/09879505383459821332noreply@blogger.com0tag:blogger.com,1999:blog-4744905985737564278.post-63999332520057168062008-05-01T06:00:00.000-07:002014-08-07T09:05:36.232-07:00Biomedical traditional Chinese medicine<table cellpadding="0" cellspacing="0" class="tr-caption-container" style="float: left; margin-right: 1em; text-align: left;"><tbody>

In this final post I want to suggest some connections
between Chinese herbal medicine and biomedicine, and highlight the
existence of a hybrid discipline that one might call 'biomedical
traditional Chinese medicine' (BTCM, I think more narrow in my meaning than Elisabeth Hsu's '<a href="http://ora.ox.ac.uk/objects/uuid:3f2af090-abce-4aff-a086-70396d97536b" target="_blank">Chinese medicine and pharmacotherapy</a>', but please c.f.).<br />
<br />
Let's begin with
the conventional arguments on Chinese herbal medicine and its
relationship to science. The first is East vs. West - polar opposites.
The cultural critique of this dichotomy follows, i.e., the idea that
both East and West are essentialist constructs, faulty to the core,
one, by analogy to Edward Said, the product of Orientalism (one might
call its opposite 'Occidentalism', <i>pace </i><a href="http://books.google.co.uk/books?id=oCIABKvG25kC&printsec=frontcover#v=onepage&q&f=false" target="_blank">Chen Xiaomei</a>). Scholars such as <a href="http://sss.sagepub.com/content/29/3/323.abstract" target="_blank">Sean Hsiang-lin Lei</a> and <a href="http://sss.sagepub.com/content/32/5-6/659.abstract" target="_blank">Vincanne Adams</a> move around the edges of this subject.<br />
<br />
Another line of commentary, developed out of the work of <a href="http://books.google.co.uk/books?id=0wWeYgEACAAJ&dq=kim+taylor+chinese&hl=en&sa=X&ei=u5gQT4z2Bca2hQfgrum1Ag&ved=0CEYQ6AEwAg" target="_blank">Kim Taylor</a> and <a href="https://docs.google.com/viewer?a=v&pid=sites&srcid=ZGVmYXVsdGRvbWFpbnxlbGlzYWJldGhoc3VwdWJsaWNhdGlvbnN8Z3g6NTE3ZDIwZGZhOWQ3MmVmYg" target="_blank">Elisabeth Hsu</a>, runs along historiographical tracks laid down by <a href="http://ruraleconomics.fib.ugm.ac.id/wp-content/uploads/Eric-Hobsbawm-The-Invention-of-Tradition.pdf" target="_blank">Eric Hobsbawm</a>,
namely, that Chinese Traditional Medicine (TCM) was 'invented' in
Maoist China and therefore is not 'traditional' at all. This revelation
is taken several steps further in the writing of the polemicist <a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2291211/?tool=pubmed" target="_blank">Edzard Ernst</a>, who condemns TCM as a sham and draws a parallel to the Nazis' fixation with homeopathy in the 1930s.<br />
<br />
All
great analyses produced by others who know far more than me - and
represented rather briefly and crudely in the above summary (and
apologies for that). I want to take a different approach . What I am
interested in describing is the modern interpenetration of ('Western')
biomedicine and Chinese herbal medicine to the extent that the two have
become indistinguishable components of a new form of biomedicine we see
today.<br />
<br />
Hsu makes a point about the
indivisibility of the 'two medicines' in a material sense, describing
how Chinese medical cures sold in East Africa combine ostensibly Western
preparations such as paracetamol with ostensibly Chinese cures based
around herbs - in the same pill (<a href="http://www.tandfonline.com/doi/abs/10.1080/01459740902848303" target="_blank">here</a>, pay wall). This represents a material form of alternative modernity.<br />
<br />
What
of this interpenetration, cast in institutional and scientific terms,
beyond the materiality of the cure itself? After all, modern biomedical
research is not about cures <i>per se</i>, but the evocation of future
medical utility in the basic biological sciences.<br />
<br />
Let's
tackle this problem in two parts. In the first, I want to map out what
contemporary biomedical TCM (BTCM) might be. Characteristics thus
established, I will then describe how it might have arisen <i>in conjunction with</i> contemporary biomedicine.<br />
<br />
<b>Biomedical Traditional Chinese Medicine (BTCM)</b><br />
Let us consider the ways in which BTCM is promoted, studied and described, using as our starting point a <i><a href="http://www.nature.com/nature/outlook/asian_medicine/" target="_blank">Nature</a> </i>supplement
dedicated to the subject. (The WHO has more recently published a similar piece, available <a href="http://www.who.int/bulletin/volumes/90/8/12-020812.pdf" target="_blank">here</a>.)<br />
<br />
The first point is the tendency in this new
discipline to describe 'modern medicine' as highly reductionist. Thus
we learn that 'modern medicine, imported [into China] from the West,
consists of chemically purified compounds that have been discovered
through scientific investigation and tested in controlled clinical
trials' and that 'for decades, European and US regulatory agencies held
the view that a drug must be either a highly purified or synthetic
agent.'<br />
<br />
The <i>Nature </i>commentary probably sounds a little
simplistic for anyone with a passing acquaintance with medical history -
a history in which American, European <i>and </i>Chinese scientists
reveal themselves to be (actually) rather sophisticated thinkers about
the nature of health, medicines and healing. The point is that we have a
biomedical straw-man (of weirdly simplistic orthodoxy) against which
the more sophisticated forces of BTCM can react.<br />
<br />
The
second hallmark of BTCM is technological boosterism - in other words,
that herbal medicine is a 'treasure house' of (now) lucrative cures
waiting to be uncovered (to subvert Chairman Mao's comment on the
matter, but not in the sense he meant it).<br />
<br />
What is BTCM, as a laboratory practice? In an interesting <a href="http://sss.sagepub.com/content/37/6/855.full.pdf" style="background-color: white;" target="_blank">article</a><span style="background-color: white;"> on South Korean research on herbal medicines, Jongyoung Kim described how
herbal screening work was boring, creativity-sapping and ultimately
soul-destroying. Junior investigators had to plow through organic
extractions and bio-assays on different herbs, producing identikit data and dull, identikit papers.<br />
<br />
This picture of labor practice will hardly surprise anyone who has visited a biomedical laboratory recently. It is the kind of repetitive work that requires no brain input and therefore can (when funds and technology allow) be
readily outsourced or automated, or both.</span><br />
<br />
There is a synergy between the practices of BTCM and those most
biomedical/<a href="http://ora.ouls.ox.ac.uk/objects/uuid%3A3f2af090-abce-4aff-a086-70396d97536b" target="_blank">neo-liberal</a> constructs, 'systems biology' and 'personalized
medicine' - but let's leave that for another day.<br />
<br />
<b>Co-construction of herbal medicine and biomedical science</b><br />
In any discussion on BTCM, attention invariably alights on <i>qinghaosu/</i>artemisinin
as proof of concept. The drug, a sequiterpene lactone, was extracted
from a herb traditionally used in Chinese medicine to treat fever. The
special significance of the drug may not be that it <i>works</i> as a
biomedicine (anti-malarial drugs are, after all, ten-a-penny), but
because it articulates a larger project of biomedical reform, a story in
which China plays a central part.<br />
<br />
Typically, the
artemisinin story is told along the lines of conventional pharmacognosy.
Accordingly, credit for the work of discovering the drug falls to <a href="http://www.laskerfoundation.org/awards/2011_c_description.htm" target="_blank">Tu Youyou</a>, the Chinese scientist who isolated the active principle. However, this telling of the story - of pharmacognosy <i>sui generis</i>
- misses out the broader significance of the drug in framing the
post-1980 construction of BTCM - and the parallel story of its
interpenetration with biomedicine.<br />
<br />
It's worth noting in
passing the coincidence between the contemporary globalization of
Chinese medicine and equivalent changes in the practice of biological
research (re-configured as 'biomedicine') that occured in the late 1970s
and afterwards.This is probably nothing more than a coincidence.<br />
<br />
Two
points. The first as follows. Even casual acquaintance with the story
of artemisinin reveals the importance of intellectual property issues in
negotiations between the Chinese government on one side, and the World
Health Organization on the other. The Chinese, by their own admission,
were obsessed with safeguarding the intellectual property around what
was actually a rather run-of-the-mill medical discovery.<br />
<br />
Indeed,
the post-1980 history of the drug was shaped by disputes over who owned
what and who had the right to make the drug. Looking back, this seems
all perfectly understandable, but in the context of the time, it is
rather curious. Here was what amounted to government-backed research,
conducted in academic centers, being pushed into a commercial context.<br />
<br />
Of course, as it turned out,
there was no way for the Chinese scientists to protect their IP, simply
because such a legal concept did not exist in China in the years when
the discovery was made (private property of any sort being anathema in a
Communist regime). The important thing is that the Chinese <i>wanted </i>to protect their IP, even if such a move was deemed legally impossible.<br />
<br />
What
is interesting is that this is a time when, even in America, the
various instruments of contemporary biomedical IP, such as routine
patenting of unproven or non-commercial discoveries, the use of material
transfer agreements, etc., were still in their infancy. Thus, I want to suggest that the evolving connections
between academic research and intellectual property were made in
important ways through the medium of artemisinin - ways of which we have
zero understanding.<br />
<br />
A second point. Chinese <i>qinghaosu </i>factories,
which were designed to make the drug, notably the Guilin and Kunming
plants, were deemed to be producing below GMP standards and therefore
the drugs they made were not suitable to export, according to inspectors
from the US Food and Drug Administration. By September 1982, Chinese
manufacture for export had been effectively thwarted. <span style="background-color: white;">But the point for the
Chinese, at least in the only account we have of the process, was to
learn how to implement GMP standards in Chinese pharmaceutical factories
(see the Project 523 account, Zhang, </span><i style="background-color: white;">et al.</i><span style="background-color: white;">, pp. 78-79).</span><br />
<br />
The willing
transfer of knowledge from American experts to China is a familiar
scenario from that era - but a possibly critical role of artemisinin in
the reform of the Chinese pharmaceutical trade needs to be investigated.
In other words, what was the role of artemisinin in the broader story
of the Chinese drug trade?<br />
<br />
I want to suggest that, while also a medicine
derived from traditional practices, artemisinin was one of the means by
which the Chinese pharmaceutical trade modernized (and perhaps, also, <i>American </i>standards
were revised and qualified). In this case, the supposed opposites of
herbal medicine and biomedicine were constitutionally inseparable.<br />

<b>Pharmaceutical industry as herbal hybrid</b><br />
Synthetics were not the be-all-and-end-all of the
modern drug trade, even in the West. Investigation (and production) of
herbal medicines was in fact stock-in-trade of at least the <i>British </i>pharmaceutical industry. Wellcome, for example, operated a <i>materia medica</i> farm
at Dartford in Kent in the 1930s, where the company grew foxgloves for
the production of the heart drug digitalis (see the picture to side -
and note the factory in the background).<br />
<br />
We can take the story into the
post-WWII period, to the 1950s - the chemical conglomerate Fisons set up
a plantation in Nicaragua to grow Ipecacuanha root (source of
emetine) [see: <a href="http://www.nationalarchives.gov.uk/a2a/records.aspx?cat=074-bwhf&cid=1-115#1-115" target="_blank">'The End of a Chapter', a printed history of Whiffen and Sons, Ltd., by Rupert S. Law, B/WHF/245, 1972</a>].<br />
<br />
My
point here is that these fragments of a yet-to-be-written history show
that herbal extracts continued to have commercial value in the
pharmaceutical industry in the mid-twentieth century. Furthermore, while
herbal medicines probably declined in value as a source of revenue for
firms after the 1950s (it was cheaper to make drugs from coal tar and
petroleum, rather than exotic herbs), the trade did not give up on them
entirely.<br />

Two
achievements of post-WWII commercial research attributable in part to
herbal medicines were the development of 'The Pill' by the firm Syntex
(story told <a href="http://www.botgard.ucla.edu/html/botanytextbooks/economicbotany/Dioscoreamed/index.html" target="_blank">here</a>); and lesser-known, Fisons' work on the anti-asthmatic drug sodium cromoglycate, or Intal.<br />

<br />
As this intriguing film shows (above), in the 1960s, a scientist called <a href="http://en.wikipedia.org/wiki/Roger_Altounyan" target="_blank">Roger Altounyan</a> initiated
research on khella tea, a traditional middle-eastern herbal remedy for
spasm. By experimenting on himself, he found that khella derivatives
were anti-allergenic (they stopped his asthma attacks from developing).<br />
<br />
The fact that Fisons would commit to such a long-term development
project on the drug - eight years - implies that herbal medicines were
taken seriously within the management of the company.<br />
<br />
<b>Roche and artemisinin</b><br />
That
brings me back to artemisinin, which like Intal, must be one of the
major triumphs of post-war pharmacognosy. In a study of herbal medicine
research at the London School of Hygeine and Tropical Medicine, <a href="http://www.sciencedirect.com/science/article/pii/S0035920306000368" target="_blank">Taylor and Berridge</a> make the point that researchers at the school were always receptive to herbal drugs - and indeed, when <i>qinghaosu </i>was
announced to the world in 1979, the school commenced research on the
drug without any qualms. In other words, herbal medicines were not a
conceptual leap for the leading academic experts of the time.<br />
<br />
In this final section I want to flesh out the artemisinin story by examining the work of the Swiss drug maker, Roche.<br />
<br />
The <a href="http://www.corptrading.org/hkcorp/cps.jsp?key=21816-be57a959" target="_blank">Roche Far East Research Foundation</a>,
an organization that operated between 1970 and 1999 (in 1987 it seems
to have been re-christened the 'Roche Asian Research
Foundation'), <span style="background-color: white;">is a little-known player in the emergence of</span><span style="background-color: white;"> </span><i>qinghaosu</i><span style="background-color: white;">. Working out what this organization actually did is rather
difficult - Swiss drug company Roche's </span><a href="http://www.roche.com/histb2008_e.pdf" style="background-color: white;" target="_blank">official history</a><span style="background-color: white;">
says nothing of it. </span><span style="background-color: white;">Accordingly, I have gathered the following data
through Google. Based in Hong Kong; its registered address was a
mysterious post office box (no. 98595) in Tsim Sha Tsui - there is also
reference to an office at 1332 Prince's Building (a tower block on Hong
Kong Island); notable staff and collaborators included Dr. Keith Arnold,
Dr. R. Laserre and Dr. T. Harinasuta.</span><br />
<br />
Publications
associated with the institution give us clues as to its work: apparently
lacking its own laboratory facilities, it funded and organized
conferences, helped Asian scientists publish their work in
English-language journals and provided grants for scientific research
and medical <a href="http://books.google.co.uk/books?id=9uGLTUlrVpwC&lpg=PA260&dq=%22roche%20far%20east%20research%20foundation%22&pg=PA260#v=onepage&q=%22roche%20far%20east%20research%20foundation%22&f=false" target="_blank">training</a> in countries like Thailand, Indonesia, Singapore, Burma and China. Areas of interest included, at a minimum, <a href="http://books.google.co.uk/books/about/Progress_in_therapy_of_bacterial_infecti.html?id=t9dANAAACAAJ&redir_esc=y" target="_blank">infectious disease</a>, <a href="http://books.google.co.uk/books/about/Mental_health_trends_in_developing_socie.html?id=GKonGwAACAAJ&redir_esc=y" target="_blank">mental health</a> and '<a href="http://books.google.co.uk/books/about/First_Regional_Seminar_on_Psychotropic_M.html?id=VikvGwAACAAJ&redir_esc=y" target="_blank">psychotropic drugs</a>'.<br />
<br />
We
can deduce that the foundation's aim was to tap medical expertise in
Asia, look around for ideas, and perform a hearts and minds function
among governments, academics and medical doctors. It was effectively an
intelligence-gathering organization, appropriately based in Hong Kong,
which, as a British colony adjacent to Communist China, served as a
wider intelligence hub throughout the Cold War.<br />
<br />
The big coup for the foundation, if one can call it that, occurred in 1979, when Keith Arnold found out about <i>qinghaosu</i>. How he actually obtained this information, we can only speculate, but the significance of it was that Roche established a <a href="http://www.sciencedirect.com/science/article/pii/S0140673684920579" target="_blank">relationship</a> with
a Chinese researcher, Li Guoqiao, at the Malaria Research Unit,
Guangzhou College of Traditional Chinese Medicine (just across the
border from Hong Kong, in Mainland China).<br />
<br />
The extent
to which these contacts benefited Roche financially is hard to gauge
(anti-malarial drugs are not major profit centers), but the company
certainly made some of the early running when G. Schmid and W. Hofheinz
of the company's pharmaceutical research department in Basel succeeded
in the first total synthesis of the drug, publishing their work in 1983 (<a href="http://pubs.acs.org/doi/abs/10.1021/ja00341a054" target="_blank">here</a>, pay wall). Roche also secured a contract as principal <a href="http://books.google.co.uk/books?id=YkoLAQAAMAAJ&q=roche+qinghaosu&dq=roche+qinghaosu&hl=en&sa=X&ei=dl8UT_OpD4eSOoK3sfAL&ved=0CE0Q6AEwBQ" target="_blank">maker </a>of the drug for the World Health Organization (WHO).<br />
<br />
What
is interesting is the way Roche moved the drug from a bit player in the
anti-malarial game to the leading treatment for the disease, often in
combination with another Roche product, mefloquine. Indeed, did Roche
actively push the use of <i>qinghaosu </i>in Thailand and Vietnam? Certainly, the Roche Far East Foundation's already-established network of academic collaborators, <a href="http://www.dfid.gov.uk/R4D/PDF/Outputs/MMV/Artemisia_annua_Artemisinin_ACTS_and_Malaria_control_in_Africa.Sept20.pdf" target="_blank">notably Professors Nick White and François Nosten in Thailand</a> are closely implicated in the story. In Vietnam, Keith Arnold directly recruited <a href="http://malaria.wellcome.ac.uk/doc_WTX062550.html" target="_blank">Professor Tran Tinh Hien</a> to the program of study and promotion of the drug.<br />
<br />
To move one step further, the apparent opposition of the WHO to the artemisinin program, typically read as an <a href="http://books.google.co.uk/books?id=q2O7AAAAIAAJ&lpg=PA285&dq=Dr.%20T.%20Harinasuta&pg=PA280#v=onepage&q=Dr.%20T.%20Harinasuta&f=false" target="_blank">ideological bias</a> against
'the East' or herbal medicine, might also be seen as an uneasiness about Roche's commercial projects. Ultimately, it seems to have been academic
collaborators, not Roche directly, who conducted extensive clinical
trials on <i>qinghaosu</i>, and vociferously argued for its use. The WHO eventually dropped its opposition and embraced the drug.<br />
<br />
What
I think we can say is that in the 1980s and 90s, 'biomedical' drug
companies like Roche seem to have been receptive to the idea of herbal
drugs - and were prepared to develop them and promote their use.<br />
<br />
<b>Conclusion</b><br />
We
know practically nothing about the actual relationship between
'traditional' knowledge and biological science in the production of drugs - but the cursory grab-bag of factoids I have assembled here
suggests a rich history in which the two forms of knowledge have been
thoroughly co-constructed.<br />
<br />
To talk in terms of binary
opposition is clearly fallacious and probably always was. If anything,
science's supposed hostility to traditional knowledge is a manufacture
of very recent vintage and has more to do with the epistemic practices
of contemporary biomedicine (inflected as they are by the US Food & Drug Administration's very particular scientific culture as the key regulator of innovation in the pharmaceutical trade) - rather than some essentialist conflict over
the 'truth' of traditional knowledge.<br />
