Information about  Cynoglossum officinale from other sources

[Wikipedia] Found in most parts of Europe: Found in most parts of Europe, and also North America, where it was accidentally introduced[4] including in British Columbia, where it is designated a noxious weed under the British Columbia Weed Control Act.[5] It lives in wet places, sand dunes, waste land and hedges.The plant owes its common and scientific name to the long greyish leaves that are reminiscent of a dog's tongue and were once given as a remedy for dog bites. Cynoglossum officinale contains tumorigenic pyrrolizidine alkaloids.[11] It is toxic to cows and is especially dangerous to pasture owners. (link added by Steve Conger)
