Steve's notes:
If it tastes like a blueberry, it is one. I've never seen or heard of anything that tastes like a blueberry and isn't. Some, like the grouse-whortleberry we used to eat in Montana, are small, red, and don't look much
English pilots in World War Two used to eat jam made of bilberries (a type of blueberry) just before flying at night, to improve their vision. It has since been proven that bilberry (and presumably the closely related other blueberries) have antho-cyanosides, which increase blood flow to the eyes.
Blueberry roots (at least the vaccinium species) can be boiled to make a tea for treating diarrhea.
Blueberry leaves can be used for a tea that will treat urinary tract infections, and stabilize or reduce blood sugar levels in diabetics.
