Mastic gum is a natural substance extracted from the trunk of the mastic tree (Pistaccia lentiscus var. chia), an evergreen shrub found in the Mediterranean and in North Africa. In some systems of traditional medicine, mastic gum has long been chewed to achieve certain health benefits.

Uses

Mastic gum is touted as a natural remedy for the following health conditions:

In addition, an aromatic oil found in mastic gum is thought to help fight bad breath. Some people also use mastic gum to stimulate circulation.

Health Benefits of Mastic Gum

In laboratory research, scientists have demonstrated that mastic gum possesses antioxidant, anti-inflammatory, antibacterial, and liver-protecting properties. Mastic gum contains a number of compounds with health-enhancing effects, including linalool (a substance also found in lavender, orange, rose, and jasmine oils).

Here's a look at several findings from the available research on the health benefits of mastic gum:

1) Indigestion

Mastic gum may help treat indigestion, suggests a 2010 study published in the Journal of Ethnopharmacology. For the study, 148 people with functional dyspepsia (a type of indigestion with no obvious cause) were assigned to receive either a placebo or mastic gum three times daily. After three weeks, indigestion symptoms were significantly lower in the group assigned to mastic gum (compared to those in the placebo group). Those symptoms included stomach pain and heartburn.

2) Cavities

In a 2006 study published in Archives of Oral Biology, researchers found that mastic gum may help prevent cavities. The study included 25 people with healthy gums, each of whom chewed either mastic gum or a placebo gum for 15 minutes. After analyzing saliva samples taken from the participants both before and after gum-chewing, the study's authors found that mastic gum was significantly more effective in destroying Streptococcus mutans (a type of bacteria closely linked to the development of cavities).

3) Cancer

Preliminary research indicates that mastic gum may offer anti-cancer benefits, according to a 2011 report published in Nutrition and Cancer. Upon review of the available research on mastic gum and cancer, the report's authors found that certain compounds in mastic gum may help inhibit the growth of cancer cells and tumors. These compounds include triterpenoids, a type of substance also available in a number of herbs (such as boswellia).

It should be noted that there currently aren't many clinical trials testing the potentially cancer-fighting effects of mastic gum, so mastic gum cannot be recommended for the prevention or treatment of cancer at this time.

Is It Safe?

Although mastic gum is generally considered safe, some people may experience allergic reactions when using mastic gum. If you experience difficulty breathing, chest pain, hives, or a rash when using mastic gum, it's crucial to discontinue use immediately.

Where to Find It

Widely available for purchase online, mastic gum (and supplements containing mastic gum) can be found in many natural-foods stores and in stores specializing in dietary supplements.
