Description
Curator's Comment: Description was created based on several sources, including http://www.merckvetmanual.com/mvm/toxicology/strychnine_poisoning/overview_of_strychnine_poisoning.html https://www.ncbi.nlm.nih.gov/pubmed/440838

Strychnine is an indole alkaloid obtained from the seeds of the Indian tree Strychnos nux-vomica. It gets its scientific name “strychnos” from Carl Linnaeus, who classified it back in 1753, but it was known to the population of India way before then. Nux vomica originates in India. Strychnine-containing baits are currently labelled for below-ground use and are intended for the control of pocket gophers. Their use as indoor pesticides has been eliminated since 1989. In the past, strychnine has been used as a pesticide to control rats, moles, gophers, and coyotes. Strychnine is highly toxic to most domestic animals. Strychnine is a competitive antagonist at glycine receptors and thus a convulsant. It has been used as an analeptic, in the treatment of nonketotic hyperglycinemia and sleep apnea.
