Aromatic Fomentation.
Take of Jamaica pepper, half an ounce; red wine, a pint. Boil them for a little, and then strain the liquor.
This is intended, not only as a topical application for external complaints, but also for relieving the internal parts. Pains of the bowels, which accompany dysenteries and diarrhoeas, flatulent colics, uneasiness of the stomach, and reachings to vomit, are frequently abated by fomenting the abdomen and region of the stomach with the warm liquor.
