Noni (Morinda citrifolia) is a tropical fruit that grows on a small evergreen tree or shrub. It's native to Southeast Asia and Australasia, but is also grown in other parts of the world, including the Caribbean and South America.
Noni fruit is typically green and lumpy, and can range in size from that of a small potato to that of a large grapefruit. It has a pungent, sour taste, and is often consumed as a juice or in dietary supplements.
Noni has been used for centuries in traditional medicine to treat a variety of ailments, including infections, inflammation, and pain. While scientific studies on noni are still limited, some research has suggested that it may have potential health benefits, such as anti-inflammatory and antioxidant effects.
