Green Ointment
Take two or three large handfuls of the fresh-gathered leaves of the Jamestown weed, (called Apple Peru in New England,) and pound it in a mortar till you have extracted the juice. Then put the juice into a tin sauce-pan, mixed with sufficient lard to make a thick salve. Stew them together ten or fifteen minutes, and then pour the mixture into gallipots and cover it closely. It is excellent to rub on chilblains, and other inflammatory external swellings, applying it several times a day.

Green Ointment
Boil the leaves of Jamestown weed in water until a very strong tea is obtained; add good hog’s lard in the proportion of three pounds of lard to one gallon of the water. Stew until the water is evaporated. Strain, and to each pound add an ounce of turpentine; add it when the lard is nearly cold.
