Abstract
Abstract An acupuncture needle is equipped with a shank portion of a first metal and a head portion of a second metal. After the shank portion is inserted through the skin, a heating element of molded charcoal having a recess therein to accommodate the head portion is slid over the head portion and rests thereon. Prior to mounting the heating element on the head portion, the end of the heating element which will face the skin in spaced relation thereto is ignited so that after the heating element is mounted, it will heat the acupuncture needle by conduction and will heat juxtaposed skin area by radiation.
