In the history of medicine, cupping has been used as an essential therapeutic technique since time immemorial. In China, cupping therapy has been practised for millennia, first using cows’ horns and then bamboo cups. These were later replaced by little metallic vases, then glass domes and finally pump suction cups. The cup is a little dome that is applied to oiled skin and works through suction. The size of the cup is chosen in relation to the area of the body being treated. A vacuum is created by pressing on the pump to eliminate oxygen. The cup is held in place by suction.
