Cupping is a method of treating disease that is caused by local congestion. A partial vacuum is created in a cupping jar, usually by means of heat, which is then applied directly to the skin. The underlying tissue is drawn up into the jar forming an area of blood stasis. This appears to bruise the area, or at least turn it a bright red. The amount of dark red or even purple blood drawn to the surface indicates the degree of stagnation. Dark blood is a sign of stagnation, which in many cases in modern terms is the amount of toxins in the blood.
Cupping is generally indicated in the treatment of Arthritic pain, abdominal pain, stomach ache, indigestion, headache, hypertension, common cold, cough, low back pain, painful menstruation, insect and poisonous snake bite.
