What specific condition can SP 3 be used to treat?

The point SP 3, also known as Spleen 3, is primarily associated with the treatment of digestive issues. This point is located on the spleen meridian and is classified as the source point for the Spleen channel. The Spleen plays a critical role in the digestive process, including the transformation and transportation of food and fluids in the body.

Acupuncture at SP 3 can help strengthen the Spleen's function, thereby improving digestion, alleviating symptoms like bloating, diarrhea, or poor appetite, and addressing conditions such as food stagnation. Additionally, it is also indicated for conditions related to deficiency, such as fatigue stemming from poor digestion.

While calming the mind, stroke treatment, and pain relief may involve other acupuncture points, they are not the primary focus of SP 3. The strong connection of SP 3 to digestive health highlights its role in treating conditions specifically related to the spleen's function, making it the most appropriate answer to the question.
