COMMON NAMES. Tickweed, Squawmint, etc.
    MEDICINAL PART. The herb.
    Description. -- This is an indigenous annual plant, with a fibrous, yellowish root, and an erect, branching stem, from six to twelve inches high. The leaves are half an inch or more long, opposite, oblong, and on short petioles; floral leaves similar. The flowers are quite small and light-blue in color.
    History. -- This plant should not be confounded with the Mentha pulegioides, or European Pennyroyal. It grows in barren woods and dry fields, and particularly in limestone countries, flowering from June to September and October, rendering the air fragrant to some distance around it. It is common to nearly all parts of the United States. It is said to be very obnoxious to fleas.
    Properties and Uses. -- It is stimulant, diaphoretic, emmenagogue, and carminative. The warm infusion, used freely, will promote perspiration, restore suppressed lochia or after-flow, and excite the menstrual discharge when recently checked. It is very much used by females for this last purpose -- a large draught being taken at bedtime, the feet being previously bathed in hot water.
