Which point serves as the Yuan Source point on the Gallbladder meridian?

The Yuan Source point on the Gallbladder meridian is located at GB-40. Each meridian in Traditional Chinese Medicine has specific points that have particular functions, and the Yuan Source points are primarily associated with their respective organ systems and are thought to be a location where the original Qi of that organ is most accessible.

Specifically, GB-40, known as "Qiu Xu" or "Qiu Point," is situated near the lateral side of the ankle, just anterior to the lateral malleolus. It plays an essential role in promoting the smooth flow of Qi and blood in the Gallbladder channel and is also utilized to address issues related to the Gallbladder organ, such as gallstones or digestion-related problems.

Other points mentioned serve different purposes based on their locations and associated functions. For instance, GB-37 is often utilized for issues related to the eyes, and GB-41 is utilized for regulating Shaoyang conditions. Liv-1 is categorized under the Liver meridian and is not related to the Gallbladder at all.

Thus, GB-40's designation as the Yuan Source point is foundational in understanding its therapeutic significance in acupuncture and Traditional Chinese Medicine.
