What is cupping?
Cupping is a folk remedy that has been widely used for a long period of time. In the beginning, it was predominantly used to treat surgical diseases such as localized blood coagulation and suppurating pustule, but nowadays the application of cupping extends to internal diseases. In the past, ox horns and bowls were used in cupping, but as it developed, cup is made from various sources, such as bamboo, porcelain, and glass, to be used.
