Role of Hijama (Cupping) in the Management of Various Diseases and Probable Mechanism of Action
Abstract: Hijama is derived from Arabic word ‘Hajm’ which literally means to suck. It involves the use of cup like vessels placed on the body surface by creating a vacuum to either let out blood from below the skin surface or just plain suction without bloodletting. Hijama evacuates blood from small vessels spread over the skin and muscles and relieves congestion from the body. It is a therapy with low cost …
