You might have heard of pennyroyal, thanks to Kurt Cobain, but you might not have consumed it before. Pennyroyal belongs to the smallest family of mint, it is far more pungent than its popular relatives. Use creatively and wisely in tea brews, stews, soups and puddings for an unexpected menthol kick. Remember that a little goes a long way.
Pennyroyal has been used to cure digestive and menstrual derangements since ancient times, but it certainly has a dark side to it. Since it is a natural emenagogue and creates a risk of miscarriage it should be avoided during pregnancy. And it is a good idea to keep it away from small children.
