In the islands, Noni is part of the art of traditional medicine. Many of us remember seeing the yellow fruits melting in glass jars in the window sills of our grandmother's house, turning translucent before transforming into a clear brown liquid. If curiosity got the best of you, you opened that jar to experience a burst of smell you weren't expecting and you just couldn't un-smell. Surprise! Its fermented!
Those traditional methods are still at the heart of what we do today as fermenting noni juice is unique to the Hawaiian tradition. Although, today we have the benefit of high quality controls and... yes... science.
Here's an interesting research paper about the pain and inflammation properties of Noni when subjected to the scientific method. Yes Tutu (grandma) was right when she told you this funky smelling liquid would keep you well.
