Alum Whey.
BOIL two drachms of powdered alum in a pint of milk till it is curdled; then strain out the whey.
This whey is beneficial in an immoderate flow of the menses, and in a diabetes, or excessive discharge of urine.
The dose is two, three, or four ounces, according as the stomach will bear it, three times a-day. If it should occasion vomiting, it may be diluted.
