Which point is classified as a Jing Well?

The Jing Well points are the first points on the channels and are associated with a variety of functions, including clearing heat, moving qi, and treating conditions related to the corresponding organ. They are considered a type of mastery point that affects the entire channel and can influence the organ system.

ST-45, known as the Jing Well point of the Stomach channel, is located on the lateral side of the second toe, and it is specifically used to treat conditions that involve excess heat, food stagnation, and psychological issues related to the Stomach, such as anxiety and irritability. Being a Jing Well point, it has the characteristic function of being able to influence and clear not only physical symptoms but also emotional conditions tied to the Stomach.

The other points listed (ST-44, ST-41, and ST-43) serve different functions and are categorized in different ways within Traditional Chinese Medicine. Each of those points has its specific applications but does not carry the same implications of treatment that Jing Well points do. Therefore, identifying ST-45 as the correct answer highlights its unique role in acupuncture practice, particularly within the Stomach channel.
