(Dorstenia Contrajerva, Radix.) _Contrajerva Root._
The qualities of this plant are alike extracted by spirit and water; the
watery decoction, however, is very mucilaginous; as it contains no
astringent matter, the salts of iron do not affect it. DOSE of the
powdered root, gr. v. to ʒss, but it is rarely used. It is considered
cordial, and diaphoretic. Has it any virtues? The Spanish Indians have
long used it as an antidote to poisons; the Spanish word _contrahiérba_
signifies antidote. OFFICINAL PREP. _Pulv._ _Contrajerv. co._ L.
