Peppermint has a fresh, minty, sweet, herbaceous aroma. Its healing application extends to nervous disorders, the respiratory tract, muscle aches and pains, and skin problems. It is not only very refreshing but stimulating as well. Aromatherapists use Peppermint in treating asthma, nausea, colic, cramps, colds, fevers, fainting, headaches, mental fatigue, flatulence, and nausea. Peppermint may also help certain emotional conditions, such as depression, shock, migraines, nervous stress, vertigo, and faintness. It is useful in general respiratory disorders as well, whether they are caused by microbes or allergies. Peppermint is known to relieve pain from toothaches, rheumatism, neuralgia, muscular pains, and painful menstrual cycles, due to its effects on the circulatory system.
