How was hemlock used to poison in ancient times?

In ancient times, small doses of the plant were used to relieve pain, with a great risk of poisoning. One species, Conium maculatum, was used to carry out the death sentence in ancient times. The Greek philosopher Socrates was condemned to death in 329 B.C.E. by drinking a potion made from hemlock.
