It is
used internally
to excite vomiting, in doses of from ten to twenty grains of the powder, or one to one and a half ounce of the infusion, every half hour until vomiting takes place. To make it act well and easily, the patient should drink half pints of warm water after each dose of the infusion. As a diaphoretic, it should be given in doses of three grains, mixed with some soft substance, such as crumbs of bread, and repeated every four hours.
Dose
of the
wine,
from twenty minims to one drachm as a diaphoretic, and from one drachm to one and a half ounces as an emetic.
Caution.
—Do not give more than the doses named above, because, although a safe emetic, yet it is an acrid narcotic poison.
