Do not understand why so many Muslims believe that cupping (hijama) is of any benefit It is no different than
acupuncture, bloodletting, phrenology, or any other medical pseudoscience. The treatment is based in pre-scientific superstitions going back 5,000 years and has simply been rebranded to more effectively market the treatment
to modern customers.
It is now just another alternative treatment, lacking plausibility, lacking any compelling evidence for efficacy, and promoted for the usual array of subjective symptoms with the usual array of handwaving justifications.
