They include chokecherry, bitter cherry, black cherry and pin cherry. Cherry fruit is great to eat, but the leaves, bark, twigs and pits of wild cherries contain dangerous amounts of a cyanide-producing compound. Children are sometimes poisoned by swallowing lots of cherry pits. Eating a few cherries with their pits will give you a stomach ache. Big doses of cyanide can cause shortness of breath, spasms, coma and even death.
Potatoes are starchy tubers produced by plants that are members of the deadly nightshade family.
They supply vitamins, minerals and fiber, no fat and nearly no salt. You could stay healthy on a diet of just potatoes and whole milk. Potatoes are good for you, but all of the green parts of the potato plant contain poisons called alkaloids. Even the potato tuber can be poisonous when it is left in the light and begins to turn green. Avoid any potato with green skin.
