This perennial is grown in East Asia. Its plant height is over 40 to 60 cm and the flowering period in Japan is August to October. The subterranean stems have contraceptive efficacy. Mentha Oil is an essential oil made by steam distillation of the terrestrial parts of the plant, and cooling to remove solids.

Part used: terrestrial part
Medicinal use: antipyretic and diaphoretic

Aggregates of numerous labiate corollas form the inflorescence.
