Having diarrhea while drinking Chinese medicine is not detoxification. There is a common misconception among the population that diarrhea in the process of taking Chinese medicine indicates that the body is detoxifying, and many people recognize this view, but it is actually incorrect. Chinese herbal medicines may contain diarrhea-inducing ingredients, such as rhubarb, which can cause diarrhea symptoms, as the treatment in Chinese medicine requires evidence-based treatment according to individual constitution. In addition, irregular herbal medicines may also cause diarrhea, and in patients who are old and frail or have underlying diseases, diarrhea is severe and may have serious consequences, so this aspect should be corrected. If necessary, the herbal prescription needs to be adjusted in time to reduce the symptoms of diarrhea, so that the herbal medicine can have the best therapeutic effect and reduce the occurrence of adverse reactions.
