Noni is an evergreen plant found throughout Polynesia. The plant bears fleshy yellowish-white fruit and is used in traditional medicine for wound healing, infections, diarrhea, skin conditions, and as tonic. It is cultivated in Hawaii and other Polynesian islands and is marketed worldwide as Noni. Fresh or fermented juices are available as drinks while capsules, pills and powders are sold as dietary supplements. Over the last two decades, products containing Noni have been heavily promoted for immunostimulation, chronic fatigue syndrome, hypertension, and cancer treatment via network marketing schemes. The FDA issued a warning letter to an Internet distributor of noni juice for presenting misleading claims of health benefits (1).
Although many of the beneficial effects of noni are unsubstantiated, in vitro and animal studies suggest that the plant extracts have antifungal (14), antitumor and immunomodulatory (3) (7) (8) (17) (18) properties. Noni also inhibits low-density-lipoprotein oxidation and has been suggested for use in preventing arteriosclerosis (15). Glycosides and other constituents isolated from the fruits and leaves have demonstrated antioxidant effects (12) (13). In addition, high concentration (>5%) of noni juice was shown to have anti-angiogenic properties in an ex vivo assay (16).
Consumption of noni juice may reduce the risk of cancer in smokers (19). An NIH funded Phase I study of noni in cancer patients has been completed at the University of Hawaii’s Cancer Research Center, but the data are yet to be published (11).
The exact mechanism of action is unknown. The aqueous extract of noni root produced a central analgesic effect in Swiss mice that was antagonized by naloxone (6). When combined with sub-optimal doses of certain chemo agents, polysaccharides from noni improved survival time and curative effects in animal model (4). Glycosides isolated from noni juice inhibited AP-1 transactivation and cell transformation in the mouse epidermal JB6 cell line (2). In addition, oral administration of noni juice reduced 7, 12-dimethylbenz(a)anthrancine (DMBA)-DNA adduct formation in C57 BL-6 mice (5). It may also reduce cancer risk by blocking carcinogen-DNA binding or by excising DNA adducts from genomic DNA (19).
Bottom Line: Noni showed anticancer effects in laboratory studies. It is being studied in cancer patients.
The juice of the noni fruit has been traditionally used in Polynesian cultures as an anti-cancer agent. Scientists have isolated a fraction from noni juice that is rich in complex sugars. This fraction, alone and in conjunction with chemotherapy drugs, is able to increase the survival of laboratory mice that have been implanted with lung cancer. Scientists are unsure exactly how noni exerts this effect, but guess that it has an immune-stimulating effect, since it has enhanced certain aspects of the immune system in laboratory studies. Furthermore, noni juice acts as an antioxidant and slows the transformation of normal cells to cancer cells in certain animal laboratory studies.
An NIH funded phase I study of noni in cancer patients has been completed at the University of Hawaii. The results are yet to be published.
However, a company-sponsored study showed that dose-related adverse effects are minimal in a noni product.
