SR Print(0) ID 1179992632 T1 STRYCHNINE T2 Poisoning & Drug Overdose, 7e YR 2018 FD 2018 PB McGraw-Hill Education PP New York, NY SN 9780071839792 LK accessmedicine.mhmedical.com/content.aspx?aid=1179992632 RD 2024/04/25 AB Strychnine is an alkaloid derived from the seeds of the tree Strychnos nux-vomica. Brucine, a similar but weaker alkaloid, comes from the same seeds. Strychnine can be found in other plants (eg, Saint Ignatius bean Strychnos ignatii, Snakewood Lignum colubrinum). It is odorless and colorless, with a bitter taste. At one time, strychnine was an ingredient in a variety of over-the-counter tonics and laxatives, and was used clinically in the treatment of cardiac arrest and snake envenomation, and as an analeptic. Although strychnine is no longer found in pharmaceuticals; it is still available as a pesticide and rodenticide. It is also sometimes found as an adulterant in illicit drugs (eg, cocaine, heroin).
