Take of China Root, and of Sarsaparilla of each one Ounce and a half, of Sassafras Root, and of the Shavings of Guiacum, otherwise called Lignum vitæ, of each one Ounce. Let the whole be cut very fine. Then put them into a glazed earthen Vessel; pouring upon them about five pints of boiling Water. Let them boil gently for an Hour; then take it from the Fire, and strain it off through Linen. This is called the Decoction of the Woods, and is often of different Proportions of these Ingredients, or with the Addition of a few others. More Water may, after the first boiling, be poured on the same Ingredients, and be boiled up into a small Decoction for common Drink.
