Mastic gum is a resin obtained from the mastic tree (Pistacia lentiscus) ). It is also known as tears of Chios, being traditionally produced on the island Chios, and, like other natural resins, is produced in "tears" or droplets). When chewed, the resin softens and becomes a bright white and opaque gum. The flavor is bitter at first, but after some chewing, it releases a refreshing flavor similar to pine and cedar). People have used mastic gum for its medicinal properties for centuries. It can be chewed like normal chewing gum, or ingested in capsule or powder form. Essential oil from mastic gum is also available.

Mastic gum has been used for a variety of health reasons, including improving digestion, oral health, and liver health. It contains antioxidants that are said to support its therapeutic properties. Some possible uses and health benefits of mastic gum include:

• Digestive health: Mastic gum has been used to relieve abdominal discomfort, pain, and inflammation. Its positive effect on digestion may be due to the antioxidants and anti-inflammatory compounds it contains. Some evidence suggests that mastic gum could also help with inflammatory bowel diseases (IBD) such as Crohn’s disease.

• Oral health: Mastic gum may help prevent dental cavities and treat stomach upset. It has also been shown to eliminate bacteria known to cause digestive ulcers. A small study had participants chew mastic gum three times a day for three weeks, and researchers observed that the participants had lower levels of bacteria that can increase the risk of cavity development in the teeth.

• Heart health: Mastic gum may help control cholesterol and blood sugar levels, which can increase the risk of heart disease and type 2 diabetes. A study in 156 healthy volunteers found that those using mastic gum had lower total cholesterol and blood sugar after 8 weeks.

Studies of mastic gum have not noted any significant or dangerous side effects. However, due to the limited research, children, pregnant women, and breastfeeding women should avoid using mastic gum. It is always recommended to check with a doctor before using mastic gum as an alternative remedy.
