Dose of the wine from twenty minims to one drachm (as a diaphoretic); and from one drachm to one and a half ounce (as an emetic).
Caution. - Do not give more than the doses named above, because, although a safe emetic, yet it is an acridnarcotic poison.
It Is used externally as a poultice, (which is made of the powder, bread-crumbs, and water; vinegar is not necessary).
When applied it should not be left on too long, as it is apt to cause ulceration of the part. From ten to thirty minutes is quite long enough.
When used internally as an emetic, a large tea-spoonful mixed with a tumbler of warm water generally operates quickly and safely, frequently when other emetics have failed.
In dropsy it is sometimes given in the form of whey, which is made by boiling half an ounce of the bruised seeds in a pint of milk, and straining off the curd. From three to four ounces of this is to be taken for a dose three times a day.
