LR13 (Zhāng Mén, “Zhāng Mén”) is the Front-Mu point of the Liver Channel of Foot Jueyin Meridian. It is located on the lateral aspect of the abdomen, directly inferior to the free end of the 11th floating rib. This point is located by having the patient lie on their side, bend the upper leg and straighten the lower leg, and raise their arm; the point is found at the tip of the elbow when it is brought to the side. It harmonizes the Liver and Spleen, regulates Qi in the Middle Jiao, invigorates blood, resolves masses and accumulations, and clears damp-heat.

Clinical notes

As the Front-Mu point of the Spleen and the Influential point of the Zang organs, Zhangmen is a primary point for harmonizing the Liver and Spleen. It is essential for treating digestive disorders stemming from Liver Qi stagnation invading the Spleen, such as abdominal pain, bloating, and diarrhea alternating with constipation. Its ability to move Qi and blood also makes it effective for hypochondriac pain and palpable masses in the abdomen.
