Mastic
The Pistacia lentiscus tree, sometimes referred to as the mastic tree, produces mastic, which is a resin. Mastic is also known as tears of Chios, Arabic gum, and Yemen gum.
Mastic has a long history of usage in traditional medicine to treat a variety of gastrointestinal problems, such as Crohn's disease and stomach ulcers. It may act as an effective natural ulcer treatment, according to more recent animal research. In additionally, one study in 38 ulcer-affected participants shows that taking 1 gram of mastic daily reduced ulcer-related symptoms by 30% more than the placebo. By the end of the two-week research period, 70% of people in the mastic group had healed ulcers, compared to only 22% of those in the placebo group.
