Shangyang Point: Detailed Introduction and Application Guide

Point Name: Shangyang Point

Shangyang Point (Shāngyáng Xué) is an important acupoint on the Hand Yangming Large Intestine Meridian in traditional Chinese medicine. This acupoint has a significant effect on regulating the body's meridian qi and blood. The "Shang" in the name represents one of the five musical tones, corresponding to the metal element; "Yang" indicates that this acupoint belongs to the Yang meridian. This name reflects the unique position of Shangyang Point in the human meridian system.

Shangyang Point is located at the tip of the finger, specifically at the radial side of the nail root of the index finger, approximately 0.1 inch from the corner of the nail. The specific location can be found by following these steps:

2. Locate the Index Finger: Find the index finger, paying attention to the nail root on the side closest to the thumb.
3. Determine the Radial Side: On the side of the index finger closest to the thumb, which is the radial side, find the point 0.1 inch from the nail root.

This acupoint is close to the edge of the nail, and gentle pressure will produce a noticeable sour and numb sensation.
