Ipecac
A naturally occurring substance with multiple properties including the ability to cause vomiting (emesis).
Ipecac is derived from dried roots of a bush called Uragoga ipecacuanha that is native to Brazil.
In the past, a sizable proportion of poison exposures in the U.S.
Were treated with ipecac.
This practice has dropped off and some experts recommend that it should be abandoned, except in rare instances.
