Where is the water point of the hand tai-yang meridian located?

The water point of the hand tai-yang meridian, which is also known as the small intestine channel, is located at the point where a loose fist is made, specifically distal to the metacarpo-phalangeal joint at the junction of red and white skin. This positioning is significant in acupuncture and traditional Chinese medicine as the specific location reflects practical anatomical landmarks that practitioners can easily identify during treatment.

In this area, the transition from red to white skin serves as a clear visual guide for locating the point. This anatomical delineation is essential as it helps practitioners maintain accuracy in point selection, contributing to the effectiveness of treatment. The water point's role in traditional Chinese medicine includes aiding in regulating the flow of water and the body’s fluids, enhancing digestive functions, and supporting overall harmony within the meridian system.

Other options describe locations relevant to different acupoints or meridian pathways, but they do not correspond to the correct identification of the water point for the hand tai-yang meridian. Understanding the precise anatomical markers for acupoints ensures practitioners can provide more effective care based on well-established principles of traditional Chinese medicine.
