Commentary

Neiguan is considered the single most important distal point for the treatment of any kind of chest pain. It is a primary point in Acupuncture Anaesthesia for chest surgery.

The Heart is considered to be the residence of Spirit and the Pericardium, as the muscule that wraps the Heart, is its protector. Neiguan is the point of choice for regulating the Heart, both at the physical level (pounding of the Heart, rhythm disorders) and at the metaphysical level (insomnia, epilepsy, mania, poor memory, loss of memory, fright, sadness and anxiety).

Finally, like other points on the Pericardium Channel, because this channel connects with the middle, Neiguan is indicated for various stomach and intestinal disorders. Specifically, Neiguan is chosen for vomiting due to pregnancy, and vomiting as a side effect of chemotherapy.
