SP 21 Acupuncture Point is called as dà bāo. Da means Large. Bao means containing. This point pertains to the major collateral of the spleen meridian. The spleen(earth) lies in the center and is related to all the Zang-Fu organs.
The Spleen Meridian begins at the big toe and runs along the inside of the foot crossing the inner ankle. It then travels along the inner side of the lower leg and thigh. Once it enters the abdominal cavity, it internally connects with the spleen and continues upward to reach the Heart Meridian. Externally, the Spleen Meridian continues moving toward the chest and branches out to reach the throat and the root of the tongue.
The Spleen Channel is a yin channel that consists of 21 points. It begins at the 1st toe and runs along the medial aspect of the foot and travels upwards along the lower leg and thigh medially. Once reaching the abdomen it continues upwards toward the chest. As with the Stomach channel the Spleen is an extensive meridian which runs for most of the entire length of the body from the 1st toe to the upper chest but its main usage in a musculoskeletal setting is of the points of the lower limb, namely SP 6, SP 9 and SP 10.
