It is possible that diarrhea after drinking Chinese medicine is a normal detoxification reaction of the drug, or it may be due to the deterioration and corruption of Chinese medicine stored for too long, or it may be due to the patient’s own constitution. Chinese medicine requires that a cure be given to the evil, and the way to get rid of the evil can be through stool, urine, or sweating. Among them, stool is the most common kind of detoxification reaction. If the patient is irritable and depressed, hot and humid, and tired, the herbal remedy may have the effect of strengthening the bowel movement and discharging the evil toxins from the body so that the five organs can be at peace. Just like food will rot if left for a long time, Chinese medicine will also deteriorate if stored unreasonably or for too long, and deteriorated Chinese medicine will mostly become acidic and produce a lot of gas. Therefore, the storage of the decoction in a bag should not be sloppy, if there is a problem, people may also have diarrhea after taking it. If the patient has a cold constitution, he or she may also have diarrhea due to the cold effect after drinking the cooling medicine that clears heat and detoxifies the body. If the diarrhea is not serious and the body is comfortable after the bowel movement, then it is usually the normal detoxification reaction of Chinese medicine, so don’t worry. If you’ve got a lot of time, you’ll be able to avoid diarrhea and other phenomena by storing your medication and regulating your diet. If it is very serious, it may be a pathological condition and you need to seek medical help.
