Acupuncture Point: Small Intestine 3 4.96/5 (56)

Small Intestine 3 (SI 3) is the gateway acupuncture point leading to the spine by way of the shoulders, neck and scapula. Often this point is combined with Bladder 62, which opens the spine from the direction of the coccyx and the lumbar spine. The two points used together make a beautiful team.

Internally this acupuncture channel crosses the heart and the intestines, thus making Small Intestine 3 a helpful point for palpitations, heart conditions, bloating, gas, constipation, and diarrhea.
