Nayak BS, Marshall JR, Isitor G, Adogwa A.

Diabetic rats were treated with noni juice or glibenclamide orally for 20 days. Both the groups had significantly lower blood glucose levels than those in an untreated group. Animals in the untreated group had significantly more fatty degeneration of the liver than those of the noni juice and glibenclamide groups. These results demonstrate the hypoglycemic and hepatoprotective activity of noni juice. (original abstract available at https://www.hindawi.com/journals/ecam/2011/875293/).
