An herb that is related to mint, shiso has a slight lemony taste yet a unique flavor of its own. Its red, heart-shaped leaves are reminiscent of red meat, hence comes one of its English names, "beefsteak plant." Besides adding color and flavor to umeboshi, shiso has strong antibacterial and preservative qualities both in the pickling process and on the person who eats them.

Mitoku Shiso Powder is made from freshly ground shiso leaves and is a tangy seasoning and colorful garnish for sushi or atop rice or noodles as a sprinkle. Shiso condiment helps the body to maintain an alkaline condition.
