Cupping therapy is an ancient form of alternative medicine in which a therapist puts special cups on your skin for a few minutes to create suction. People get it for many purposes, including to help with pain, inflammation, blood flow, relaxation and well-being, and as a type of deep-tissue massage.

Cupping therapy might be trendy now, but it’s not new. It dates back to ancient Egyptian, Chinese, and Middle Eastern cultures. One of the oldest medical textbooks in the world, the Ebers Papyrus, describes how the ancient Egyptians used cupping therapy in 1,550 B.C.
