In Treatment

Yin Wei connects all of the yin channels, holds and controls the yin of the body. It controls the inside of the body, the heart, jing and the blood. Useful for yin deficiency particularly when caused by lack of self nurture. It controls the blood and is used for blood deficiency.

Also controls the heart and is used for psychological disturbance. The Nan Jing difficulty 29 states that an imbalance in Yin Wei Mai produces pains in the heart. This may relate to an obstruction in the chest, possibly related to cold, obstruction in circulation – particularly for Ki and Sp channels, and counter-current for Lv and Ren Mai. It is often used to tonify the yin particularly when it is exhausted often due to emotional disturbance. Ki9 is useful to use in combination with the master and coupled points to tonify the yin.
