This treatment takes place in a warm, heavily-blanketed bed. Make a hot tea made by infusing Pennyroyal (28 gm) and Wood Sage (28 gm) with boiling water (750 ml); cover closely and allow to stand ten minutes. Then take as warm as convenient in 125 ml doses every half hour until freely perspiring. Vomiting may occur but this will merely clear the stomach. Take the Foot_Water_Bag treatment concurrently. In the morning, sponge the body down with equal parts vinegar and warm water.
