Climbing Nightshade

Poisonous Properties:
Climbing nightshade, especially in its green immature fruits, contains steroidal alkaloids, which have caused poisoning in cattle and sheep. Humans may have been poisoned after ingesting immature berries. Recent experiments show that the mature red berries contain only a small amount of toxin and have little chance of harming children. The immature green berries of climbing nightshade have been shown to be toxic to hamsters and mice. Mature red berries did not cause symptoms in mice. The leaves are mildly poisonous as well.
