[Recognition on toxicity of traditional Chinese drugs].

Our ancestor found that some of the Chinese herbal drugs were toxic during their clinical practice. They graded the toxicity of Chinese herbal drugs into three degrees and thought that the term "toxicity of the Chinese herbal drugs" could be used in a broad and a narrow sense. In modern times, toxic components of the Chinese herbal drugs and their toxic mechanisms, especially the toxicity on the kidney, were further revealed. The factors that affect the toxicity of the Chinese herbal drugs include the species, preparation, dose and environment. To prevent the toxicity of the Chinese herbal drugs, we must strengthen the management of the Chinese herbal drugs. On the other hand, doctors' recognition of the toxicity of Chinese herbal drugs should be enhanced. At the same time, patients should be told to decoct and take Chinese herbal drugs correctly.
