Morinda citrifolia fruit juice augments insulin action in Sprague-Dawley rats with experimentally induced diabetes.
Horsfall AU, Olabiyi O, Aiyegbusi A, Noronha CC, Okanlawon AO.
Feeding of Morinda citrifolia (noni) fruit juice to diabetic rats for 4 weeks lowered fasting blood glucose. When noni juice ingestion was combined with insulin treatment, fasting blood glucose levels were lower even further than with either noni juice or insulin alone.
