Shou San Li (LI10) is commonly used for neck tightness, shoulder pain, diarrhea, and tennis elbow. Shou San Li (LI10) is located on the outer surface of the forearm and three fingers breadth below the elbow crease when the elbow is bent 90 degrees. To use acupressure on this point, (1) locate the point then (2) use a deep, firm pressure to massage and stimulate the area for 4-5 seconds.
When applying acupressure, try to relax and breath deeply as you massage the area. The massage and the acupressure can be done by yourself, or by someone else who is there to assist you.
A few scientific papers cited that Shou San Li (LI10) along with Zu San Li (ST36) enhance the regularity of gastric myoelectrical activity  which may indicate its association in affecting gastrointestinal functions.
