What are the active medicinal properties of noni?

noni fruit, leaves, flowers, stems, bark, and roots are still used to make medicine for a long list of ailments. However, the effectiveness of noni for these uses has not been proven. A study of noni freeze-dried fruit extract is underway at The National Center for Complementary and Alternative Medicine, but the results are not yet in. In the meantime, the FDA has issued multiple warnings to noni manufacturers about health claims that aren’t backed up by fact.

People take noni by mouth for colic, convulsions, cough, diabetes, painful urination, stimulating menstrual flow, fever, liver disease, constipation, vaginal discharge during pregnancy, malarial fever, and nausea. It is also used for smallpox, enlarged spleen, swelling, asthma, arthritis and other bone and joint problems, cancer, cataracts, colds, depression, digestive problems, and gastric ulcers. Other uses include high blood pressure, infections, kidney disorders, migraine headache, premenstrual syndrome, stroke, pain, and sedation.

The fruit juice is used for arthritis, diabetes, high blood pressure, muscle aches and pains, menstrual difficulties, headaches, heart disease, AIDS, cancers, gastric ulcers, sprains, depression, senility, poor digestion, atherosclerosis, circulation problems, and drug addiction.

The leaves have been used in medicines for rheumatic aches and swelling of the joints, stomachache, dysentery, and swelling caused by a parasitic infection called filariasis. The bark has been used in a preparation to aid childbirth.
