Which acupuncture point is classified as He Sea?

The classification of acupuncture points into different categories, such as He Sea points, is based on their anatomical locations and the functions they serve in traditional Chinese medicine. The He Sea points are associated with the transformation and transportation functions of the body. SI-8, known as "Soothing the Elbow," is the correct choice as it is located at the elbow joint and is classified as a He Sea point for the Small Intestine channel. This point is typically used to harmonize the stomach and intestines, alleviate pain, and address issues related to digestion.

In contrast, the other points listed are categorized differently based on their anatomical locations and functions within the meridians. Understanding the specific classification of each point is vital for their effective application in acupuncture treatment.
