How much would you have to ingest for it to be a deadly amount?
-
It varies by plant and species.
The LD50 for a mouse is 0.27 mg/kg for the main toxin aconitine. That would be approximately 18 milligrams to kill 50 percent of humans that weigh about 150 lbs if the toxicity is similar to mice. The link said as little as 2 to 5 milligrams can kill an adult.
Their highest concentration is from 0.2 to 3% in the young tubers. That would require as little as 33*18 mg or roughly half a gram of plant to kill half the people. It would be much less to kill some people. It would probably take more leaves but that isn't very much.
This amount would likely kill you. It is a half a gram. It is about one small bite.
