Pennyroyal Uses
Used as a repellent for fleas in Ancient Rome, Pennyroyal was thought to purify air and water and was hung in the rooms of sick people because of its strong aroma. It’s an excellent insect repellent. Since it is not absorbed through the skin, rubbing the leaves on exposed areas of your body can be as effective at repelling mosquitoes, flies, gnats and ticks. It is also soothing as a skin wash to relieve itching and rash. Pet collars, woven from the freshly gathered stems and leaves, will deter fleas, and bunches of the herb, hanging to dry, will also keep pests at bay. Many commercial products contain the oil of pennyroyal in insect-repellent preparations.
