STRYCHNINE

Strychnine is a white, odourless, crystalline powder, almost insoluble in water, with an intensely bitter taste. It is a poisonous alkaloid obtained from the dried seeds of nux vomica and other species of Strychnos. In small does it is administered as a heart stimulant. In toxic doses strychnine causes convulsions which are interspersed with periods of relaxation, which gradually reduce until the convulsions are almost continuous, and contraction of the chest muscles prevents breathing and causes death.
