Dangers: Some people have reported throat issues and stomach upset after eating peppervine fruit. Limit yourself to small servings until you know how your body will react.
The berries are ripe when they are black. Most people consider these berries somewhat sweet and grape-tasting tasting but get a weird tickle in the back of their throat after eating one or more berries. This tickle is actually due to tiny needles of calcium oxalate which are denfensive measure of the Peppervine. Excessive consumption of calcium oxalate will result in chemical burns in your throat and possibly nasty kidney stones. Drying the berries or cooking them will help remove some of these oxalates. Making wine from them may also work.
