Infusion of Tamarinds and Senna.
Take of tamarinds, one ounce; senna, and crystals of tartar, each two drachms. Let these ingredients be infused four or five hours in a pint of boiling water; afterwards let the liquor be strained, and an ounce or two of the aromatic tincture added to it. Persons who are easily purged may leave out either the tamarinds or the crystals of tartar.
This is an agreeable cooling purge. A tea-cupful may be given every half hour till it operates.
This supplies the place of the decoction of tamarinds and senna.
