If the face is bright and rosy, there is strong hard activity. If there is a deficiency, the complexion is pale. The heart condition is also reflected on the tongue. If red moist, there is abundant blood flow. If it is pale, a deficiency exists.. The heart is also the center of consciousness and mental functioning.
The heart meridian starts at the armpit and goes between the biceps along the forearm and hand, and ends at the little finger
