Clinical notes

As the Yuan-source and Shu-Stream point of the Spleen meridian, SP3 is profoundly important for strengthening the Spleen's fundamental functions of transformation and transportation. It is a primary point for Spleen qi deficiency, manifesting as fatigue, poor appetite, abdominal distention, and loose stools. Its Shu-Stream nature also makes it effective for dampness and heaviness in the limbs. It is frequently paired with ST36 to tonify Spleen and Stomach qi.
