What was rhino horn used for in Traditional Chinese Medicine (TCM)?
At times during the 3000-year history of TCM, rhino horn was used to treat infections and was believed to reduce fever. It was never used alone, but in combination with Chinese herbs.
Given that rhinos are endangered, is rhino horn still used today?
In China, Taiwan and South Korea it has been completely banned from use in medicine since about 1993. Also in China it is only permitted for use in research to identify substitutes, and is no longer listed in medical reference books. But in Vietnam – a huge market for illegal rhino horn – it is being used as a hangover cure by the nouveau riche. It is also being promoted to treat cancer. There is no scientific basis for such claims.
Has there been scientific research into the effectiveness of rhino horn in medicine?
In one human study, researchers in Taiwan found that rhino horn temporarily reduced fever in children, but it was no more effective than aspirin. Animal studies done in the UK and South Africa found no pharmacological effects of rhino horn – or any other animal horns.
What alternatives are there to rhino horn?
There are plenty of alternatives; the studies I just mentioned found traditional plant-based medicines, such as Radix Isatidis, are great substitutes. They are now promoted by traditional medicine authorities in South-East Asia.
How did you become involved in wildlife conservation?
In 1997, in my role as president of the American College of Traditional Chinese Medicine, the World Wildlife Fund contacted me for a meeting. There and at later conferences, I learned about the challenges of conservation – including the fact that there was no dialogue between the TCM and conservation communities. So I decided to play a bridge-building role. By 1999, we had a meeting in Beijing that brought together the scientific, medical, conservation, and TCM communities.
Why is this partnership between the medical and conservation communities so important?
TCM is no longer exclusive to China or South-East Asia. It is now used in 70 countries in Africa, North and South America and Europe. There is an urgent need to educate consumers about the crisis we face in terms of illegal poaching and black market sale of endangered animals. Also, greater demand is having negative impacts on individual medicinal species and the ecosystems in which they thrive. Chinese herbal formulas use over 11,000 plants, animal products, and mineral substances – about 80 percent of which are collected in the wild.
So how can we protect the species put at risk?
Long-term survival of medicinal plant and animal species depends on well thought-out, widely adopted conservation strategies. They are in everyone’s interest – including those of us in the TCM community.
