Annual herb, up to 50cm tall, native to eastern North America; aromatic peppermint-like smelling, much-branched; leaves small, thin, narrow; flowers pale blue.

"In the early 20th century, it was used in domestic medicine, in the form of a warm infusion, to promote perspiration and as an emmenagogue. Upon ingestion, one of its components, pulegone, metabolizes into hepatotoxic metabolites that depending on dosage can lead to organ failure, seizures, and death. In the 19th century it was recommended for flea control..." [[https://en.wikipedia.org/wiki/Hedeoma_pulegioides|wikipedia]]
