History. -- It is found in low grounds, dry hills, and plains, from Ohio and Illinois extending southward, and flowering in Juy and August. The whole plant is used, and has the taste and odor peculiar to the mint family.
Properties and Uses. -- It is diaphoretic, stimulant, antispasmodic, carminative, and tonic.
