Zusanli

Zusanli, also known as ST36, is one of the most frequently used points in traditional Chinese medicine. It lies on the leg on the stomach meridian, about three cun below the lower edge of the patella and one cun lateral to the anterior crest of the tibia.

In TCM theory, Zusanli is a major point for tonifying qi and blood, supporting the stomach and spleen, and boosting overall vitality. It is commonly selected to address digestive disorders and general weakness, and it is often included in regimens aimed at improving resilience and recovery.

Typical indications in clinical practice include nausea and vomiting, abdominal pain, diarrhea or constipation, poor appetite, fatigue, and immune-related conditions. It is also used to support recovery from illness and surgical procedures, as well as to relieve certain types of pain in the leg or knee.

Mechanistically, traditional accounts describe regulation of the stomach meridian and strengthening of defensive qi. Modern investigations have reported effects on gastric motility, immune function, and endorphin release after stimulation. However, the quality and consistency of evidence vary by condition, and high-quality trials are still needed to confirm specific benefits. Safety-wise, ST36 is generally considered safe when performed by trained practitioners, with possible minor soreness, bruising, or transient discomfort at the site.
