The Pycnanthemum Virginicum, or Prairie Hyssop, noticed under the class of stimulants, if taken freely in the form of warm infusion, acts promptly as a diaphoretic. It may be employed in sudden colds, checked perspiration, and in the early stages of febrile and inflammatory diseases with advantage as a diaphoretic. It is quite similar to hyssop, rosemary, and the mints, in its properties.
