Does have a clinic but it is only in operation two days of the week.
The procedure is safe and approved by the government of Qatar, and the lady therapist is fully qualified and a very professional.
The amount of cups used will vary according to your specific ailment from what I know, and of course depending on whether you are going in for wet or dry cupping. That again will be upto the therapist to decide.
Personally I know first hand people who were cured of certain chronic ailments following proper and regular therapy, including my husband(he got cupped at the souq waqif place by the male therapist. Mariam center is a strictly ladies only zone!)
