Cure for Felons
Boil up in any iron vessel of sufficient capacity, (say four or six quarts,) enough yellow dock root to make a strong liquor. When sufficiently boiled, and while the liquor is as hot as can be borne by the hand, cover the kettle with a flannel cloth to keep in the heat and steam, hold the hand or finger affected under the cloth, and in the steam, and in five minutes the pain will cease. If it should return, heat the liquor, and do as before.
