POLEO-MENTA tea contains pennyroyal (known in Spain as "poleo", and is a species of mint), and in Spain it is combined with peppermint to make one of the most popular herbal teas: poleo-menta, or translated into English, Pennyroyal-Mint tea. Pennyroyal has been recorded in history as far back as the first century AD when it was mentioned by Roman naturalist Pliny and Greek physician Dioscorides. In the 17th century, English herbalist Nicholas Culpeper wrote about some uses for the plant including its role in women's ailments, venomous bites, and digestion. The infusions of the leaves have been used in the treatment of weakness and stomach pains. Today in Spain this herbal tea is used in the same way that peppermint tea is used in the UK, and many people believe they are the same. However, while the natural properties of Pennyroyal and Peppermint tea are basically the same, their flavour is different. If you enjoy your cup of peppermint tea, you may want to give a try to Pennyroyal-Mint tea too!
