Noni juice, made from the fruit of the noni tree, is marketed as a supplement with healing abilities for diseases such as cancer and asthma. Although these claims are often exaggerates, scientific studies have shown noni juice to be effective for maintaining health and protecting the body from diseases. Noni can also be consumed in capsule form. Seek the advice of a medical professional before using noni juice to prevent, treat or cure any medical condition.


Morinda Citrifolia L., commonly known as noni, is a small evergreen tree that grows in many tropical areas. Tahitian noni has been used in Polynesian folk medicine for more than 2,000 years. Tahitians used every part of the plant for medicinal and non-medicinal purposes. The roots and bark were used as a dye for both everyday and ceremonial clothing. Hundreds of companies currently market noni juice brands. The juice itself tastes bitter, but is available in a sweet, unfermented form. Although manufacturing methods vary by brand, it generally involves cutting pieces of the noni fruit, washing them and storing them in sanitized tanks for two months to allow fermentation to occur. It is then filtered and pasteurized before it is bottled and brought to the market.

Protective Antioxidants

Evidence supports the use of Tahitian noni juice in cancer prevention. A study published in 2001 in the “Annals of the New York Academy of Sciences” concluded that thea popular brand of noni juice contains protective antioxidants that fight the cancer-initiation process. The researchers state that noni juice may prevent disease in general and contribute to overall health.

Immune System Benefits

Noni juice may support the immune system, according to authors of a study published in February 2008 in the “Journal of Ethnopharmacology.” When inflammation, an immune response, occurs, the body is more susceptible to infections like the cold and flu. Cannaboid receptors in the brain send signals that protect the body from inflammation and pain. Noni juice may support the ability of the cannaboid receptors to counteract inflammation in the body, according to the study.


Noni juice appears to be safe even at high doses, according to an authors of a review paper published in 2006 in the "Journal of Food Science.” The analysts looked at factors such as weight gain, changes in blood composition and similar biological markers of disease formation in tissues of the body, and concluded that noni juice is non-toxic and safe for consumption.
