Mastic gum is obtained from a multi-branched shrub rarely growing higher than 12 feet, found scattered over the Mediterranean region in Spain, Portugal, France, Greece, Turkey, Northern Africa, and the Canary Islands. This gum has traditionally been used in the perfume industry, as chewing gum in many cultures, along with being a traditional medicinal agent.(3)

H. pylori Infection

Mastic gum has been reported to inhibit H. pylori, a bacterial invader that lives in the mucous of the stomach lining, which can lead to stomach ulcers and other complications.(4) In a human clinical study, 5 male subjects and 1 female subject were treated with mastic extract in powder form at a dose of 1 g, twice daily. At the end of seven days of treatment, all six patients experienced complete relief. After 4 weeks of treatment, endoscopic healing was found in 5 patients. No side effects or abnormalities were reported.(5) A randomized pilot study in 52 patients suffering from H. pylori infection found that mastic gum (350mg tid x 14d or 1.5gm tid x 14d) eradicated the infection in approximately 38% of the patients vs. 77% using pharmacotherapy.(11)

Mastic gum is thought to exerted a mild antisecretory and cytoprotective effect on gastric and duodenal mucosa, protecting the body from ulceration.(6) A double-blind clinical trial was carried out on 38 patients with symptomatic and endoscopically proven duodenal ulcer to compare the therapeutic responses to mastic gum (1 gm daily, 20 patients) and placebo (lactose, 1 gm daily, 18 patients) given orally over a period of two weeks.(7) Symptomatic relief was obtained in sixteen (80 percent) patients on mastic and in nine (50 percent) patients on placebo, while endoscopically proven healing occurred in fourteen (70 percent) patients on mastic gum and four (22 percent) patients on placebo. Mastic has also been reported to inhibit neutrophil activation in the presence of H. pylori neutrophil activating protein.(12)

Other Uses

Mastic gum has been reported to have in vitro antifungal activity.(8) Mastic gum has also been reported to have antibacterial activity, being active in vitro against E. coli and S. aureus.(9)  The antibacterial activity of mastic gum has been reported effective in reducing dental caries in a small human study.(13) A laboratory study found mastic gum effective against Porphyromonas gingivalis, a pathogen linked to gingivitis.(14)

Laboratory studies also report anti-cancer activity against various human tumor cell lines.(15),(16),(17) Mastic gum was found in an in vitro study to enhance maspin promoter activity by suppressing ARE binding activity and enhancing Sp1 binding activity in prostate cancer cell lines.(18) Gum mastic has also been reported to inhibit the proliferation and cell cycle progression in prostate cancer cells by suppressing NF-kappaB activity and the NF-kappaB signal pathway.(19)

Mastic gum has also been reported to have anti-inflammatory effects in laboratory studies, including inhibition of the production of both nitric oxide (NO) and PGE2 by activated macrophages mostly via a cytotoxic action.(20)  The anti-inflammatory activity of mastic gum was also reported in a small human trial to significantly decrease the activity index and the plasma levels of inflammatory markers IL-6 and CRP in patients with mildly to moderately active Crohn’s disease.(21)
