How fast does Wolfsbane kill you?
Marked symptoms may appear almost immediately, usually not later than one hour, and "with large doses death is almost instantaneous". Death usually occurs within two to six hours in fatal poisoning (20 to 40 mL of tincture may prove fatal).
How much Wolfsbane is lethal?
According to several reports the lethal dose of aconitine ranges between 1−5 mg. Severe intoxication may already occur at doses as low as 0.2 mg [7,10,11]. The approximate fatal dose is 2 mg of pure aconitine, 5 mL of aconite tincture, and 1 g of the plant material [6].
