Other Proposed Uses

  • Numerous Uses
Morinda citrifolia , also known as noni or Indian mulberry, is a small evergreen shrub or tree of the plant family Rubiaceae. Native to the Pacific islands, Polynesia, Asia, and Australia, it grows up to 10 feet high. The leaves are 8 or more inches long, dark green, oval shaped, and shiny, with deep veins. The flower heads are about an inch long and bear many small white flowers. These heads grow to become the mature fruit, 3 to 4 inches in diameter with a warty, pitted surface. Noni fruit starts out green, turns yellow with ripening, and has a foul odor, especially as it ripens to whiteness and falls to the ground.
Some cultures may eat noni fruit in times of scarcity (the unripened fruit is less noxious). Traditional Polynesian healers have apparently used the fruit for many purposes including bowel disorders (constipation and diarrhea), skin inflammation, infection, mouth sores, fever, contusions, and sprains—but it is said that only sick and desperate people will take it, due to its unpleasant odor and bitter taste. However, the primary indigenous use of this plant appears to be of the leaves, as a topical treatment for wound healing.
In Chinese medicine, the root of M. officinalis is also a standard medication (known as bai ji tian or pa chi tien) used for the digestive system, kidneys, heart, and liver.
Other traditional uses for the plant include making a red dye from the bark and a yellow dye from the root.

Safety Issues

Although use of noni is not commonly associated with side effects, comprehensive safety studies have not been performed. A small number of case reports hint that, in rare cases, use of noni might cause severe liver damage, potentially leading to a need for liver transplant. 8-9 The risk is believed to be very low, however, if it exists at all. 10 Nonetheless, people with liver disease, or who take medications that can harm the liver, or who consume alcohol to excess should not use noni. Maximum safe doses in young children or pregnant or nursing women remains unclear.
