Xi-Cleft point of the Yang Wei Mai

Clinical notes

As the Xi-cleft point of the Yang Wei Mai, Jinmen is a critical point for acute conditions involving external pathogens and the body's protective Qi, particularly sudden, severe disorders like seizures, syncope, and acute pain. Its ability to pacify internal wind makes it valuable for epilepsy, convulsions, and opisthotonus, especially in children. Clinically, it is often used in combination with Shenmai (BL62) to strongly open the lateral aspect of the body and treat headache, dizziness, and pain along the Bladder channel.
