Question

toxin Humans eat rhubarb stems without ill effects, while cattle may die from eating the leaves, which seem to contain two different toxins. ˈtɑksən

Accepted Answer

A substance produced by a living organism (such as bacteria) that is highly poisonous to other organisms. Long before chemists started creating poisons from scratch, humans were employing natural toxins for killing weeds and insects. For centuries South American tribes have used the toxin curare, extracted from a native vine, to tip their arrows. The garden flower called wolfsbane or monkshood is the source of aconite, an extremely potent toxin. The common flower known as jimsonweed contains the deadly poison scopolamine. And the castor-oil plant yields the almost unbelievably poisonous toxin called ricin. Today we hear health advisers of all kinds talk about ridding the body of toxins; but they're usually pretty vague about which ones they mean, and most of these “toxins” wouldn't be called that by biologists.
