Mastic is a unique and very beneficial plant for health, mainly for the stomach. 1/4 of a teaspoon in a glass of water every morning on an empty stomach for 1 - 2 months can greatly reduce stomach bacteria, as well as microorganisms (bacteria and fungi) in the small intestine (dermatitis). Mastic, which has the nickname "natural antibiotic," removes microorganisms from the body (as they stick to it) and are eliminated in the feces. The only downside is that it also takes away the good bacteria in the intestine, so it should not be used for more than 1-2 months.
