Abstract: The social reports of liver injury， kidney injury and carcinogenesis induced by Chinese medicine have caused a certain degree of panic in the public. The passive impact of these reports on Chinese medicine has surpassed that of "abolishing the theory of TCM and preserving the use of Chinese medicine". This paper discusses how to correctly deal with the toxicity of Chinese medicine， how to avoid divorcing TCM theory from practice， and how to seek the results without evidence on the basis of the TCM basic theory. It is believed that a fair conclusion can be reached through changing the perception attributing the toxicity of Chinese medicine to the whole Chinese medicine discipline， applying the scientific logic principles correctly， and evaluating the efficacy and toxicity of Chinese medicine in a fair， objective， comprehensive and scientific way. Only by real scientific spirit， scientific attitude and scientific method can TCM scientific be realized.
