SP9 is the He-Sea (Water) point of the Spleen meridian and is renowned as the most important point for resolving dampness from any part of the body. It is extensively used for edema, urinary dysfunction (difficulty, retention, or incontinence), diarrhea, and damp-heat conditions in the lower jiao such as leucorrhea or painful urination.
