Biodiversity Breakdown May Threaten Chinese Medicine

Some 150 scientists and business people from China, the United States, the United Kingdom, Japan, Cuba, Denmark, the Republic of Korea and Brazil are attending the three-day seminar to discuss the conservation of animals and plants used in medicines. Professor Chen Changdu of Beijing University said that China had made efforts to deal with the decline of wild medicinal plants.

The Chinese have been using sea horses as ingredients in traditional medicines for a thousand years, but recently they have started to worry about the survival of this species.

At the Third International Seminar on Science and Technology in Biodiversity Conservation and Sustainable Utilization, Dr. Liu Mingsheng said that China used 250 tons of dried sea horses every year in a score of remedies, importing 90 percent of the creatures from Vietnam, the Philippines and India.

However, in its natural state the sea horse is on the verge of extinction, according to Liu, a doctor with a Chinese medicine company from southern Hainan Province.

"The business of Chinese medicine will be severely affected if medicinal creatures like sea horses die out one day," he said.

China makes efforts to deal with decline of medicinal plants

Christine Leon of the British Royal Botanical Garden said that there were more than 2,000 clinics dispensing Chinese medicine and many British universities offer programs on Chinese traditional medicine, which has illustrated the popularity of traditional treatments.

However, the growing demand for such medicines has made conserving wild plants more difficult, she said.

She suggested using herbal medicine containing stable chemical ingredients and expanding the cultivation of medicinal herbs.

Professor Chen Changdu of Beijing University said that China had made efforts to deal with the decline of wild medicinal plants.

Some 600 market gardens growing such crops with a total area of six million mu (400,000 hectares) had been set up across the country.

Fortunately, the latest gene technology including molecular cloning offers a solution to the problem of shrinking resources for Chinese medicines, said Xiao Peigen, a member of the Academy of Engineering of China.

An artificial breeding program for sea horses has been developed in Hainan, and is expected to produce 50 tons within three years, Xiao said.
