What type of point is H-3 classified as?

H-3, or Heart 3, is classified as a He-Sea point. In Traditional Chinese Medicine, He-Sea points are located at the elbows and knees, corresponding to the location where the qi of a meridian intersects with the body's interior. These points are particularly important as they have a deep influence on internal organ function, specifically those linked with the specific meridian.

Heart 3 is significant in the regulation of heart qi and blood, and it plays a role in calming the heart and spirit. This classification also aligns with the general function of He-Sea points in tonifying and nourishing the corresponding organ system, which in this case is the heart.

Other classifications such as Entry, Exit, or Meeting points have different physiological and therapeutic implications. For example, Entry points are where qi enters a channel, Exit points are where qi exits, and Meeting points are locations where multiple channels converge. Although all these points have their own unique functions and therapies, H-3's specific classification as a He-Sea point highlights its key role within the Heart meridian in treating conditions related to that organ, particularly affecting the heart’s relationship with emotions and blood circulation.
