Mastic gum (Pistacia lentiscus) is a unique resin that comes from a tree grown in the Mediterranean island of Chios. For centuries, the resin has been used to improve digestion, oral health, and liver health. It contains antioxidants that are said to support its therapeutic properties. Depending on your individual need, mastic gum can be chewed as gum or used in powders, tinctures, and capsules. You can also apply mastic essential oil topically to help treat certain skin conditions. A 2005 report found that mastic gum can be used to relieve abdominal discomfort, pain, and inflammation. Mastic gum’s positive effect on digestion may be due to the antioxidants and anti-inflammatory compounds it contains. Further research is needed to learn more about the exact mechanisms in which mastic gum works. The iconic PDO Chios Mastic gum marries perfectly with the Extra Virgin Οlive Οil, creating an excellent salad dressing product. Use it in salads but also in more special recipes.
