Which acupuncture point is used to regulate the intestines and alleviate diarrhea and dysenteric disorders?

The acupuncture point that is commonly used to regulate the intestines and alleviate diarrhea and dysenteric disorders is ST-37, known as Shangjuxu. This point is located on the stomach meridian and is specifically indicated for gastrointestinal issues. It is frequently utilized in Traditional Chinese Medicine (TCM) for its ability to strengthen the spleen and stomach, thereby helping to regulate the digestive system and promote normal bowel function.

ST-37 is particularly effective in addressing both acute and chronic diarrhea, as well as dysentery, conditions characterized by frequent and urgent bowel movements with soiling or mucus in the stool. By stimulating this point, practitioners aim to help restore balance in the digestive system and alleviate the symptoms associated with these disorders.

In the context of the other options, while ST-39, located distal to ST-37, is also related to the lower gastrointestinal tract and can assist with similar conditions, ST-37 is more prominently recognized for its direct role in regulating the intestines. ST-38 and LI-11, while valuable acupuncture points for various health issues, do not have the same direct application for regulating intestines and treating diarrhea and dysentery as ST-37 does.
