Cupping is a form of treatment that involves lighting a small flame and placing it inside a rounded cup. The cup is then placed onto a patient’s back, creating a vacuum and suctioning to the patient’s skin. This process is repeated several times across the back in different locations. An alternative form of cupping involves using a suction device to draw the air out of the cup, removing the need for a flame. Cupping increases the circulation of blood and reduces the build up of lactic acid.
