"In March 2011 three systematic reviews were analyzed for the effectiveness of wet and dry cupping in which two out of three showed some evidence for effectiveness of cupping for pain. Favorable effects were shown when wet cupping was combined with adjuvant conventional treatments. However, one of the three reviews showed little effectivess for cupping for stroke rehabilitation. Few randomized control trials have been done to examine the effectiveness of cupping and many studies published are of low quality or have many limitations.[5]

A study by Ahmed and colleagues was carried out in order to evaluate the efficiency of cupping [hijama] therapy in management of rheumatoid arthritis. To sum up they concluded cupping [hijama] combined with conventional medical therapy has several advantages. It significantly reduces the laboratory markers of disease activity and it modulates the immune cellular conditions particularly of innate immune response NK cell % and adaptive cellular immune response SIL-20 (Ahmed, Madbouly, Maklad $ Abu-Shady, 2005)[6]

Using a pre-post research design, 70 patients with chronic tension or migraine headache were treated with wet-cupping. Three primary outcome measures were considered at the baseline and 3 months following treatment: headache severity, days of headache per month, and use of medication. Results suggest that, compared to the baseline, mean headache severity decreased by 66% following wet-cupping treatment. Treated patients also experienced the equivalent of 12.6 fewer days of headache per month. We conclude that wet-cupping leads to clinical relevant benefits for primary care patients with headache. Possible mechanisms of wet-cupping's efficacy, as well as directions for future research are discussed.[7]

There is some evidence that wet-cupping is effective in the treatment of nonspecific low back pain.[8] Studies have also shown some evidence that it may be effective in the treatment of post-herpetic neuralgia.[9] For the treatment of cancer, there is no scientific evidence to suggest that hijama confers any health benefits.[10]" According to Wiki it IS good for you....
