Can Traditional Medicine Cure COVID-19? China’s Take

Around the world officials are advising people to be wary of alternative treatments for covid-19. The opposite is true in China, where remedies known as traditional Chinese medicine (TCM) are being heavily promoted by the state. In January 2020, as the crisis escalated, the health ministry listed TCM treatments among those it recommended for the disease. It sent nearly 5,000 specialists to Hubei to administer them to patients (including sufferers at a sports centre in Wuhan that was turned into a TCM hospital for people with mild symptoms). Now China is keen to promote its remedies abroad.  TCM practitioners have joined Chinese medical teams sent to help manage outbreaks in Cambodia, Iraq and Italy. In mid-March, 2020 state media quoted a Tanzanian health official saying that China’s use of TCM for covid-19 may be “a model” for Africa to follow…

The use of animals in TCM sometimes involves appalling cruelty. One of the TCM remedies that the health ministry has recommended for use in the treatment of covid-19 patients includes powdered bear bile. In China this is often extracted from live bears kept in grim farms even though its active ingredient can be created synthetically. In February 2020 China banned the sale of wild animals as food—close contact in markets between live specimens and merchants may have helped the coronavirus to leap from animal to human. But the new rules do not prevent trappers and breeders from selling animal parts for use in TCM.

Officials do not say that traditional remedies can cure covid-19. But they do claim that TCM can reduce death rates by preventing patients with mild or moderate symptoms from developing more serious ones. They also say that TCM can speed up recovery. A website set up by China Daily, a state newspaper, called “Fighting covid-19 the Chinese way”, says that TCM can “remove the trash which causes illness”, leaving the virus “no room to survive”.

How to Save the Rhino: Fake Rhino Horns Flood the Market

Rhinoceros horns are big business. Traditional Chinese medicine uses them to treat rheumatism and gout… And Yemeni craftsmen carve them into dagger handles. A kilogram can thus command as much as $60,000, so there is tremendous incentive for poachers to hunt the animals. Since almost all rhinoceros populations are endangered, several critically, this is a serious problem. Some conservationists therefore suggest that a way to reduce pressure on the animals might be to flood the market with fakes. This, they hope, would reduce the value of real horns and consequently the incentive to hunt rhinos.

That would require the fakes to be good. But Fritz Vollrath, a zoologist at Oxford University, reckons his skills as a forger are up to the challenge. As he writes in Scientific Reports, he and his colleagues from Fudan University, in Shanghai, have come up with a cheap and easy-to-make knock-off that is strikingly similar to the real thing.  The main ingredient of Dr Vollrath’s forged horns is horsehair. Despite their differing appearances, horses and rhinos are reasonably closely related. Horses do not have horns, of course. But, technically, neither do rhinos. Unlike the structures that adorn cattle and bison, which have cores made of bone, the “horns” of rhinoceros are composed of hairs bound tightly together by a mixture of dead cells.  Examination under a microscope showed that hairs collected from horses’ tails had similar dimensions and symmetry to those found in the horns of rhinos. 

The next task they tackled was making a suitable glue. This is made from a fibrous protein-rich glue of the sort produced naturally by spiders and silkworms. They bundled the treated horse hairs as tightly as they could in a matrix of this glue, and then left the bundles in an oven to dry.  The result was a material that, with some polishing, looked like rhino horn….DNA analysis would certainly reveal fakes, but such analysis is complicated and therefore hard to do in the sorts of back rooms in which rhino-horn sales tend to take place. The forgeries passed other tests with flying colors, though…

Low Risk-High Rewards: Killing Endangered Species

The animals’ meat, hides and, above all, tusks are money-spinners. East Asia is the biggest market for ivory and for many illegally traded products, such as animal parts used in traditional Chinese medicine (TCM)—tiger bones, rhino horns, pangolin scales—or in its cuisine—pangolin meat, for example. In July,  2019 the authorities in Singapore seized 8.8 tonnes, about 300 elephants’-worth, of ivory, along with 11.9 tonnes of pangolin scales, from some 2,000 of the anteaters, the world’s most widely trafficked endangered mammal. The annual profits of the trade in illegal wildlife products are estimated at between $7bn at the low end and $23bn. This makes it the fourth-most profitable criminal trafficking business, with links to others—slavery, narcotics and the arms trade..

Athough China is trying to curb illegal trade, it is also promoting TCM as one of its civilisation’s great contributions to the world. It has indeed made breakthroughs, such as artemisinin, now a widely used defence against malaria. Artemisinin is isolated from the plant Artemisia annua, sweet wormwood, a herb employed in TCM….Conservationists are alarmed that in 2019 the World Health Organisation (WHO) gave TCM respectability by including diagnoses for 400 conditions in its influential International Classification of Disease. 

The WHO approved in June 2019 a new version of its International Classification of Diseases, a highly influential document that categorizes and assigns codes to medical conditions, and is used internationally to decide how doctors diagnose conditions and whether insurance companies will pay to treat them. The latest version, ICD-11, is the first to include a chapter, chapter 26, on TCM.
