Dragonfly Organic peppermint infusion is just that – 100% peppermint leaf & nothing else. It is specially dried in hot air chambers, a process which takes only 4 hours compared to the usual drying time of several days & ensures that its volatile oils remain potent. Peppermint is a perennial herb that has been popular for centuries for its deliciously fresh taste & reviving properties. It is said that Greeks & Romans crowned themselves with peppermint leaves at their feasts & adorned their tables with its sprays.A hybrid of watermint & spearmint, it is occasionally found wild with its parent species, but it was only recognised as a distinct species by an English botanist in the 17th Century. It soon became cultivated widely & such was its popularity that, by 1750, it was grown commercially around the London area.
