     The American Pennyroyal differs largely from the European  Mentha pulegium  in its botanical characters, but its action, as a medicine, is very like it. Our species is extensively used, in domestic practice, as an aromatic stimulant and carminative in colic of children; a diaphoretic in the beginning of colds (Pennyroyal Tea); and in large doses of a hot infusion, together with the pediluvium, in amenorrhoea. In the latter trouble, if of recent occurrence, it will often bring on the menses, nicely; and, combined with a gill of brewer's yeast, it frequently acts well as an abortivant, should the intender be not too late with her prescription. The oil is anti - emetic, anti - spasmodic, and rubefacient in rheumatism; with raw linseed oil, it makes an excellent dressing for recent burns. The oil has been recommended as an ointment to keep off gnats, ticks, fleas, and mosquitoes; many who have camped in the northern woods, have anointed their hands, neck, and face with this body, to guard against the pests of that region, but with only partial success.
     The herb and  Oleum Hedeomae  are officinal in the U. S. Ph.; in the Eclectic Dispensatory, the oil and  Decoctum Hedeomae  are recommended. (Millspaugh’s Medicinal Plants).

Habitat: This species is indigenous to North America, where it ranges from Canada to Iowa, and southward. It grows upon the most arid spots of open woods and fields, and blossoms from July to September. (Millspaugh’s Medicinal Plants).
