A safety study of TAHITIAN NONI Juice from Tahiti was conducted with ninety-six healthy volunteers. For 28 days, participants consumed one of four daily quantities of noni juice: 0 mL (placebo), 30 mL, 300 mL, or 750 mL. All daily dose formulations were standardized to 750 mL by making up any volume differences with the placebo. Hematology, biochem...

The antioxidant properties and toxicity profile of roasted noni (Morinda citrifolia L.) leaf infusion were evaluated. The 2,2-diphenylpicrylhydrazyl (DPPH) radical scavenging activity was greater than green tea infusion (81.6 ± 0.9% vs. 57.5 ± 1.8%, P < 0.001). The mean quercetin and kaempferol contents of roasted noni leaf infusion, as prepared by...
