Recently, the traditional knowledge of Chios mastiha production was recognized as an Intangible Cultural Heritage of Humanity by UNESCO. Chios gum mastic is also known as mastiha is the resinous material obtained from the Pistacia lentiscus tree, grown on the island of Chios in Greece, where it has traditionally been used as a healthy food for the gastrointestinal tract. The use of Chios mastiha as a digestive dates back to Hippocrates in the 5th century BCE and has been carried through the ages. The plant has a unique lemony balsam-like smell, which can permeate the air of the Mastichochoria, the villages on Chios that produce mastic gum. NutriCology Mastic Gum is formulated with authentic Chios mastiha that supports a healthy balance in the gastrointestinal tract, including the oral cavity and stomach. It also supports the healthy metabolism of cholesterol, and blood pressure within normal ranges. It is free of wheat and gluten, dairy, eggs, soy, fish, shellfish, peanuts, tree nuts, and corn. Since 1979, NutriCology has used only the purest raw materials available, and has implemented strict quality control procedures in every stage of production, including inspection of raw materials, manufacturing, packaging, and storing. NutriCology fully discloses all ingredients, both active and inactive, on every product label, so consumers can make fully informed choices for their nutritional support. We define hypoallergenic as free of all common allergens, specifically, wheat, corn, soy, gluten, dairy, eggs, fish, crustacean shellfish, tree nuts, and peanuts. Many very sensitive individuals who react to supplements, in general, are able to tolerate NutriCology products. Originating with the ground-breaking oxidant/antioxidant work of Stephen Levine, Ph.D., we were one of the first to introduce truly hypoallergenic products to the market.
