Bo He Tincture & Alcohol-Free Extract

Bo He (Mentha haplocalyx, classified by Kew as part of Mentha canadensis), the Chinese field mint, is a creeping perennial of the mint family, Lamiaceae, native to China, Korea, Japan, and eastern Siberia and grown as a crop in Jiangsu, Anhui, and Jiangxi. It spreads by runners into patches 30 to 60 centimeters tall, with square, often purplish stems, opposite oval toothed leaves, and dense whorls of tiny lilac to white flowers set in the leaf axils rather than in a terminal spike. The crushed leaves release a sharp, cooling menthol scent; the Chinese crop is a major source of natural menthol. We extract the dried herb.
