It is also known as the Arm Yang Ming Large Intestine Meridian. This starts from the tip of the index finger then runs between the thumb and the index finger. It travels along the back of the forearm and the front side of the upper arm until the highest point at the shoulder. From this tip it branches off into two paths: an internal one travels to the lungs, diaphragm and large intestine, the other trails externally upwards to the neck, cheek, entering through the gums and lower teeth then curves around the upper lip and to the opposite side of the nose. Imbalance in the Large Intestine Meridian can cause
Diarrhea,
Constipation dysentery or oral problems such as toothache.
