Decoction of Logwood.
Boil three ounces of the shavings, or chips, of logwood, in four pints of water, till one half of the liquor is wasted. Two or three ounces of simple cinnamon-water may be added to this decoction.
In fluxes of the belly, where the stronger astringents are improper, a tea-cupfull of this decoction may be taken with advantage three or four times a-day.
