Clinical notes

As the He-Sea and Earth point of the San Jiao channel, Tianjing is a major point for transforming phlegm and clearing heat anywhere along the channel's pathway. It is highly effective for local conditions like elbow pain and tennis elbow, but its influence extends to the neck, shoulder, chest, and even mental-emotional states involving phlegm-heat, such as mania or epilepsy. Its ability to treat both scrofula and chest conditions highlights its role in resolving phlegm accumulation in the upper body.
