Mastic is a tree. People use the sap (resin) from the trunk to make medicine.
Mastic is used for conditions such as stomach and intestinal ulcers, long-term swelling (inflammation) in the digestive tract (inflammatory bowel disease or IBD), infections, and wound healing, but there is no good scientific evidence to support these uses.
In manufacturing, mastic resin is used in the food and drink industries and in the production of chewing gum.
Practitioners of alternative medicine have long touted mastic gum as a natural remedy for indigestion, acid reflux, peptic ulcers, inflammatory bowel disease (IBD), respiratory problems, gum disease, and various bacterial or fungal infections. The aromatic oils in mastic gum can also help fight bad breath.
Mastic gum contains a number of compounds thought to have medicinal effects, including linalool (also found in orange, rose, and jasmine oils) which alternative practitioners say can treat stress, inflammation, muscle pain, and insomnia.
Possible Side Effects
Although mastic gum is generally considered safe and well-tolerated, it is unknown at what point a dose may become excessive or what the consequences of long-term treatment may be. Despite centuries of use, there has been little research about mastic gum’s long-term safety.
Mastic gum may cause allergy in some. The mastic tree belongs to the Pistacia family of plants, which also includes the pistachio tree (Pistacia vera). People allergic to pistachio nuts (or its close cousin cashew nuts) may also be allergic to mastic gum.
