This species of Mint is a native of most parts of Europe, one of its popular names is 'Pudding Grass,' formerly used in stuffings using pepper and honey. It is the smallest of the Mints with the flowers held in whorled clusters. Like most of its near relatives, Pennyroyal is highly aromatic, perhaps even more so than any other Mint. An infusion of the leaves, known as Pennyroyal Tea, is an old-fashioned remedy for colds and menstrual derangements.
