False Hellebore
One of the most violently poisonous plants of the coastal rainforest is false hellebore (also known as Indian hellebore). This tall but unassuming plant grows in wet areas and is lethal if consumed. Even drinking water from where it grows has been known to cause stomach cramps.
In Chinook jargon, the historical trade language of the west coast, this plant was referred to as ‘skookum’ root, with ‘skookum’ meaning powerful or brave. Despite its toxic nature, this plant has enormous medicinal value for First Nations cultures, though practitioners would have to be extremely careful about consumption — something we do NOT recommend.
