Strychnine (pronounced (British) or (U.S.)) is a very toxic (LD50 = 1 mg/kg), colourless crystalline alkaloid used as a pesticide, particularly for killing small vertebrates such as rodents. Strychnine causes muscular convulsions and eventually 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 in the world. Its taste is detectable in concentrations as low as 1 ppm.
