Which point is a jing-river point on the Stomach channel?

The correct answer is ST-41 because it is defined as a jing-river point on the Stomach channel. Jing-river points are located on the channels where the energy (Qi) is known to flow more rapidly, and they often correlate with specific functions and radical changes in the body that relate to the movement of Qi.

In the case of ST-41, being situated on the ankle, it serves as a critical point for regulating the Stomach's function, influencing both digestion and the flow of Qi through the middle jiao (the upper part of the abdomen). In traditional Chinese medicine, jing-river points are commonly utilized to treat conditions associated with the respective channel, such as gastrointestinal issues and patterns of deficiency.

Other choices like ST-40, ST-34, and ST-36 do have their own specific uses, but they do not hold the classification of a jing-river point, which is particularly linked to ST-41 on the Stomach channel. This distinction is crucial for understanding the therapeutic actions associated with each acupuncture point and effectively applying this knowledge in clinical practice.
