Common questions

Ranunculus asiaticus carries the same protoanemonin and often in higher concentration. Treat florist ranunculus as the bigger risk, especially the tubers.

Can a dog get poisoning from lying in a buttercup field?

Skin contact can cause mild redness and itching on hairless areas, but serious illness needs actual chewing or eating. Rinse the coat if you notice irritation.
