Ipecacuanha, in the materia medica, a West-indian root, of which there are two kinds, distinguished by their colour, and brought from different places, but both possessing the same virtues, though in a different degree. The one is grey, and brought from Peru; the other is brown, and is brought from the Brazils: and these are indifferently sent into Europe under the general name of ipecacuanha.

These two sorts have been by some supposed to be the roots of two different plants: but this is a mistake; the only difference is, that one grows in a different place, and in a richer and moister soil, and is better supplied with juices than the other.

Ipecacuanha is an excellent, mild, and safe emetic; it is also a noble refrigerant; and, given in doses too small to vomit, is the greatest of all remedies for a dysentery. Small doses of ipecacuanha, are an excellent remedy in diarrhoeas of a more simple kind; and in the flour albus we hardly know a better medicine.

Ipomaea, in botany, a genus of the pentandria monogymina clas. The corolla is funnel shaped; the stylos is globular; and the capsule has three cells. There are eighteen species, none of them natives of Britain.
