Hijama (wet cupping therapy) involves the application of cups through vacuum to certain points on your body. Once cups are in position blood is drawn into the cups through small skin incisions made prior. The aim of Hijama is to extract stagnated or congested blood from certain points around your body. The theory is that such blood could slow down the delivery of much needed oxygen, mineral electrolytes, vitamins, enzymes, immune system cells & antibodies  to your cells, tissues and organs. With stagnated or congested blood present in your body; your cells, tissues and organs may not function at the best and so latter become progressively weak, inefficient or easily overcome by Bacteria, Infection etc.

It was researched that wet cupping therapy treated effectively diseases with different etiologies and pathogeneses e.g. rheumatoid arthritis, hypertension, migraine, carpal tunnel syndrome, fibromyalgia, cellulitis and others. Medical and scientific bases underlying cupping therapy and introduce Taibah theory as a novel evidence-based scientific mechanism to explain it. Briefly, in Taibah theory, wet cupping therapy is a minor surgical excretory procedure related scientifically to the principles of renal glomerular filtration and abscess evacuation, where a pressure-dependent excretion of causative pathological substances occurs. Causative pathological substances include disease-causing substances and disease-related substances (that result during disease pathogenesis). Negative pressure applied to skin surface causes local collection of filtered and interstitial fluids containing causative pathological substances at skin upliftings inside cups. Scarifying skin upliftings followed by cupping causes a pressure gradient and a traction force across the skin and capillaries to excrete collected fluids with causative pathological substances and cause bleeding at puncture sites. This increases filtration at both capillary ends and causes clearance of blood and interstitial spaces from causative pathological substances.

Wet cupping therapy benefits from the suction pressure, phenomenon of reactive hyperemia, nitric oxide production and skin scarifications (openings in skin barrier) in enhancing natural excretory skin functions, improving lymphatic and capillary circulations and restoring homeostasis. Reported causative pathological substances of rheumatoid arthritis include autoantibodies, immune complexes, soluble interleukin-2 receptors, inflammatory mediators, certain cytokines, prostaglandins, toxic cellular products and rheumatoid factor, while causative pathological substances of carpal tunnel syndrome include malondialdehyde, interleukin 6, prostaglandin PGE- 2 and progressive edema (causing pain). Wet cupping therapy-induced filtration pressure may excrete those causative pathological substances in cupped blood.
