Peppermint offers a healing touch for many ailments—sunburn, headache or muscle pain. To release mint’s medicinal properties, crush leaves first using a mortar and pestle or blender. For headaches and muscle cramps, make a paste of crushed leaves and water, place between pieces of cheesecloth (or other thin cloth), and apply to skin at the site of pain. For a tension headache, apply the poultice to the base of your neck. For sunburn, mix crushed leaves with cool water, strain, and spritz the water onto the burn. Menthol in peppermint feels cooling to the skin.
