Strychnine (
/ˈstrɪkniːn/; also US /ˈstrɪknaɪn/ or /ˈstrɪknɪn/) is a highly toxic (LD50 = c. 16 mg/kg in rats, 1–2 mg/kg orally in humans ), colorless crystalline alkaloid used as a pesticide, particularly for killing small vertebrates such as birds and rodents. In Australia it is also placed on steel jawed wild dog traps. This is done to ensure that the animal is not entrapped for overly long periods before death occurs. Strychnine causes muscular convulsions and eventually death through asphyxia or sheer exhaustion. The most common source is from the seeds of the Strychnos nux vomica tree. Strychnine is one of the most bitter substances known. Its taste is detectable in concentrations as low as 1 ppm.
