General poisoning notes for Solanum dulcamara

Climbing nightshade (Solanum dulcamara) is a naturalized woody vine that is found along fencerows, among shrubbery, and at wood edges across most of southern Canada. The plant, 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 (Alexander et al. 1948, Cooper and Johnson 1984, Hornfeldt and Collins 1989).
