The herbal tradition of China is valued scientifically, as well as being a fascinating and popular tradition. Scientists working in China and Japan during the past four decades have demonstrated that the herb materials contain active components that can explain many of their claimed actions. Modern drugs have been developed from the herbs, such as treatments for asthma and hay fever from Chinese ephedra, hepatitis remedies from schizandra fruits and licorice roots, and a number of anticancer agents from trees and shrubs. Several popular formulations produced in China, called “patent medicines,” are relied upon daily by millions of Chinese (in China and abroad), such as the Bupleurum Sedative Pills and Women’s Precious Pills that invigorate the energy, nourish the blood, calm tension, and regulate menstruation, and Yin Chiao Jie Du Pian, which is a reliable treatment for the early stages of common cold, sore throat, and influenza.
More than three hundred herbs that are commonly used today have a history of use that goes back at least 2,000 years. Over that time, a vast amount of experience has been gained that has gone towards perfecting their clinical applications. According to Chinese clinical studies, these herbs, and others that have been added to the list of useful items over the centuries, can greatly increase the effectiveness of modern drug treatments, reduce their side-effects, and sometimes replace them completely.
The main reason that more Westerners are turning to Chinese herbs rather than local herbs is because of the vast scope of experience in using the Chinese materials. In every province of China, there are large schools of traditional Chinese medicine, research institutes, and teaching hospitals, where thousands of practitioners each year gain training in the use of herbs. The written heritage of Chinese medicine is quite rich. Ancient books are retained, with increasing numbers of commentaries. New books are written by practitioners who have had several decades of personal experience or by compilers who scan the vast diverse modern literature and arrange the results of clinical trials into neat categories.
