Cupping is mainly through the meridians, acupuncture points and viscera are connected, so through the external suction will stimulate the acupuncture points on the surface of the body, which generally allows people to feel the smooth flow of qi and blood, and strengthen the body. Traditionally gossip, in general, is for physical therapy, but it should be reminded that because the skin pores are in a state of stretching after cupping, this can easily lead to cold in the external environment entering the body, thus inducing a stroke. So after large cupping, you must pay attention, do not expose the cupping area to the outside, and do a good job of keeping warm.
