Peppermint essential oil is commonly used by aromatherapists for a variety of purposes. The oil is distilled from the leaves and other parts of the peppermint plant. According to the Center for Complementary and Alternative Medicine, peppermint oil is traditionally used to calm nausea and indigestion, ease headaches and soothe irritable bowel syndrome. Although peppermint oil is safe in small doses, it can produce unwanted side effects, especially in sensitive or allergic individuals. Consult your doctor before using peppermint oil.
