Antimicrobial: All types of mastic gum have anti-bacterial and anti-fungal properties, and it has long been used in the treatment of skin disorders and other infections. Historically mastic gum was even used to treat bronchial infections.
Ulcers and H. pylori: Mastic gum has been shown to help eliminate H. pylori in the digestive tract, a bacterium that can cause gastritis and peptic ulcers. Interestingly, supplementation for only 2 weeks has been shown to benefit peptic ulcers, by reducing symptoms and helping to promote healing.
Dental Health: Chewing mastic gum can reduce bacterial plaque in the mouth by up to 41%. It has been shown to help prevent tooth decay and gingivitis as well. This is likely why mastic gum was used for thousands of years to freshen the breath. Of note for current health, good oral health is tightly linked with digestive and cardiovascular health.
Cholesterol Regulation: Regular consumption of mastic gum has been clinically shown to reduce cholesterol levels, which can reduce the risk of cardiovascular disease.
