Noni Fruit on a Tree Phone Case

I took this picture of the Noni in the Cook Islands after someone native told me that it is the "headache fruit", which means it can cure headaches. But not only that, it seems to be able to reduce all kinds of pains, swellings, stings etc and now is sold in bottles as a juice. I personally liked the shape/texture of the fruit, that's why it interested me in the first place.
