Shiso, otherwise known as perilla, beefsteak plant, Chinese basil, or purple mint, is a member of the Lamiaceae or mint family. For centuries, growing perilla mint has been cultivated in China, India, Japan, Korea, Thailand, and other Asian countries but is more often classified as a weed in North America. Perilla mint plants are often found growing along fences, roadsides, in hay fields or pastures and are, hence, more often termed a weed in other countries. These mint plants are also quite toxic to cattle and other livestock, so it’s no wonder why shiso is considered more of a noxious, undesirable weed in some area of the world
