What is "schizonepeta"

Schizonepeta (Japanese catnip) is a genus of herbs. It should not be confused with the true catnips of the genus Nepeta (also Lamiaceae) known for their euphoria-inducing effect on domestic cats.

Used as a medicinal herb, Schizonepeta tenuifolia, (family Lamiaceae), is cultivated chiefly in the provinces of Jiangsu, Zhejiang and Jiangxi, China. The above-ground parts are collected in autumn, or early winter, and dried in the shade.

Its Chinese name is Jing Jie (荊芥) pronounced jīng jiè ( pinyin). Other names include Herba seu Flos Schizonepetae Tenuifoliae, keigai (Japanese), and hyonggae (Korean).
