This is a tree fruit, can be eaten as a snack, partial sweet some called sweet corner, partial sour some called sour corner, huh! As for whether there is a medicinal effect I do not know.

Anyways, I always eat sweet corner. It's very delicious.

By the way, there are sold in the market in bags of sugar pickled horn or something, is this thing, but is peeled and pickled with sugar! It's also very tasty!

But don't eat too much Doha, eat too much will fall teeth, teeth feel soft, because it is too acidic. Oh!
