Admittedly,Tu won the prize mainly for her success in obtaining the pure substance of qinghaosu,later known as artemisinin (now a standard drug for malaria) from sweet wormwood,a traditional Chinese herbal medicine.But since its extraction method is poles apart from the typical TCM methodology of mixing various herbals,it can hardly be seen as an achievement of TCM.In other words,TCM practitioners may still use dried sweet wormwood to treat malaria patients today,but few of them would consider using artemisinin.
However,TCM methodology certainly contributed to Tu’s findings.Tu said she drew inspiration from the fourthcentury Chinese pharmacist Ge Hong,who suggested in a book that drinking the juice obtained from sweet wormwood soaked in water can treat malaria.
“It occurred to me that high temperatures could have destroyed the (antimalaria) activity,” Tu told the Associated Press.
Before Tu,researchers had tried to extract something from the same herb to treat malaria,but failed since they had done that at high temperatures.Tu switched to using ether (乙醚)at lower temperatures and succeeded in extracting artemisinin.
Despite this,extracting artemisinin is purely modern pharmaceutical method and the product is no different from other chemical medicines in terms of production methodology.
Some people may have attempted to promote the role of TCM by attributing Tu’s findings to it and portraying her winning of the Nobel Prize as a sign of its international recognition.While it is understandable,such a stance will only backfire and do harm to the healthy growth of TCM.
