Chinese medicine:
Under the guidance of Chinese traditional medical theory, drugs collected, processed, prepared, explained the mechanism of action and guided clinical application are collectively referred to as traditional Chinese medicine. In short, traditional Chinese medicine refers to substances that are used to prevent, treat and diagnose diseases and have rehabilitation and health care functions under the guidance of traditional Chinese medicine theory. Traditional Chinese medicine mainly comes from natural medicines and their processed products, including plant medicines, animal medicines, mineral medicines and some chemical and biological products. Because most Chinese medicines are plant medicines, there is a saying that "all medicines are based on grass".
