What are the common herbs used for diarrhea

There is no such thing as a common Chinese medicine for diarrhea. The treatment of diarrhea requires evidence-based treatment, which is divided into acute diarrhea and chronic diarrhea, and is usually clinically used in the form of Huo Xiang Zheng Qi San, Si Shen Wan, and so on.
Huo Xiang Zheng Qi San is composed of Huo Xiang, Angelica dahurica, and Dabu Pi. It has the efficacy of dispersing cold and dampness (dispersing cold and dampness in the body), eliminating filth and stopping vomiting (removing filth and evil qi in the body to stop vomiting). It is used in treating cold and fever (fear of cold and fear of heat), headache, nausea and vomiting, and diarrhea with intestinal sounds (hyperactive intestinal sounds and diarrhea). It is prohibited for those who are allergic to this product.
Si Shen Wan is composed of nutmeg and bone marrow. It has the effects of warming the kidney and dispersing cold (warming the kidney to dispel cold), astringing the intestines to stop diarrhea (relieving diarrhea by enhancing the function of intestinal astringency). It is used for diarrhea caused by deficiency of kidney yang (deficiency of yang qi in the kidneys), which is characterized by intestinal tinnitus and abdominal distension, loose bowel movements, loose diarrhea in the early morning (diarrhea at about five o’clock in the morning), and prolonged diarrhea (diarrhea for a long time but not stopping). It is forbidden for those who are allergic to this product.
If you have any related symptoms, please consult a doctor in time. Chinese medicine treatment should be applied under the guidance of a professional Chinese medicine practitioner, and should not be used on its own.
