[Discussion on postpartum hypogalactia treated with Shaoze (SI 1) based on the theory of "milk-blood homology"].

In traditional Chinese medicine, small intestine meridian and the functions of small intestine are extensively involved in the procedure of milk formation, i.e. transformation, transportation and connection. Shaoze (SI 1) communicates the meridians of hand- and hand-. It enhances the connection of the small intestine with the heart, spleen and stomach. It is the -well point for unblocking and moistening to promote the transformation and transportation of and blood and improve lactation. This acupoint is specifically characterized as promoting lactation in the small intestine meridian and is valuable considerably in clinical practice of hypogalactia of deficiency pattern/syndrome.
