Pennyroyal is often found in cottage gardens, as an infusion of the leaves, known as Pennyroyal Tea, is an old-fashioned remedy for colds and menstrual derangements.
Perennial, 1 foot. Like all the Mints, this is a rampant
grower. Propagate in the same way as Mints.
Like most of its near relatives, Pennyroyal is highly aromatic, perhaps even more so than any other Mint, containing an essential oil resembling in properties that of other mints, though less powerful. The flavour is more pungent and acrid and less agreeable than that of Spearmint or Peppermint.
Pennyroyal was in high repute among the Ancients. Both Pliny and Dioscorides described its numerous virtues. In Northern Europe it was also much esteemed, as may be inferred from the frequent references to it in the Anglo-Saxon and Welsh works on medicine.
