Diarrhea after drinking Chinese medicines for tonifying qi and blood and for tonifying the spleen and stomach may be caused by a weak body, hindering the transportation and digestion function of the spleen and stomach, and containing cold medicines. 1. Weakness: If the patient’s body is weak, he will not be subject to tonic, and taking a large amount of traditional Chinese medicine to replenish qi and blood and to replenish the spleen and stomach will stimulate the gastrointestinal tract of the organism, leading to a decline in the function of the spleen and stomach, which will not be able to absorb the nutrients effectively, and diarrhea will occur. 2. Obstruction of the transport function of the spleen and stomach: Because tonic medicines are generally more nourishing and greasy, it will be easy to obstruct the transport function of the spleen and stomach, due to the lack of transport will cause diarrhea, but usually only occasional diarrhea. 3. Containing cold drugs: Some herbal medicines for tonifying the spleen and stomach contain cold drugs, so patients may experience diarrhea. If the symptoms of diarrhea continue to worsen, you should go to the hospital in a timely manner to avoid delaying the condition.
