Is Ranunculus ternatus toxic to humans?
There have been no toxic effects found yet for ranunculus ternatus, with a specific emphasis on the word "yet". If it follows suit with most (if not all) of the other species in the Buttercup genus, it will cause harm if ingested. Plants of this genus are poisonous when eaten raw, and if ingested can cause blistering of the mouth and gastrointestinal tract, extreme salivation, bloody diarrhoea, and colic. It's not even safe to touch these plants without protective gear, as the ranunculin it contains is broken down into protoanemonin when handled, which results in skin irritation, also known as contact dermatitis.
