There are several varieties of Peppermint. The two chief, the so-called ‘Black’ and ‘White’ mints are the ones extensively cultivated. Botanically there is little difference between them, but the stems and leaves of the ‘Black’ mint are tinged purplish-brown, while the stems of the ‘White’ variety are green, and the leaves are more coarsely serrated in the White. The oil furnished by the Black is of inferior quality, but more abundant than that obtained from the White, the yield of oil from which is generally only about four-fifths of that from an equal area of the Black, but it has a more delicate odor and obtains a higher price. The plant is also more delicate, being easily destroyed by frost or drought; it is principally grown for drying in bundles – technically termed ‘bunching,’ and is the kind chiefly dried for herbalists, the Black variety being more generally grown for the oil on account of its greater productivity and hardiness.
White Peppermint is a very important and commonly used remedy, being employed by allopathic doctors as well as herbalists. It is also widely used as a domestic remedy. A tea made from the leaves has traditionally been used in the treatment of fevers, headaches, digestive disorders (especially flatulence) and various minor ailments. An infusion is used in the treatment of irritable bowel syndrome, digestive problems, spastic colon etc. Externally a lotion is applied to the skin to relieve pain and reduce sensitivity.
The essential oil in the leaves is antiseptic and strongly antibacterial, though it is toxic in large doses. When diluted it can be used as an inhalant and chest rub for respiratory infections. The essential oil is used in aromatherapy. Its keyword is “Cooling”.
Peppermint is one of the best carminative agents available. It has a relaxing effect on the visceral muscles, anti-flatulent properties and stimulates bile and digestive juice secretion, and so can relieve intestinal colic, flatulent dyspepsia and other associated conditions.
The volatile oil acts as a mild anesthetic to the stomach wall, which helps to relieve the vomiting of pregnancy and travel sickness. Peppermint plays a role in the treatment of ulcerative colitis and Crohn’s disease. It is most valuable in the treatment of fevers and especially colds and flu.
As an inhalant it can be used as a temporary treatment for nasal catarrh. Where migraine headaches are associated with the digestion, this herb may be used. As a nervine it eases anxiety and tension. In painful periods it relieves the pain and eases tension. Externally it relieves itching and inflammation.
Peppermint oil is useful in combating flatulence and mild indigestion. Many over-the-counter stomach aids contain Peppermint to both enhance the taste as well as the effectiveness of the medicine. However, in a strange bit of irony, Peppermint is something of a trigger food for many suffering from acid reflux and may cause their symptoms to worsen.
How does it work? Peppermint oil seems to reduce spasms in the digestive tract. When applied to the skin, it can cause surface warmth, which relieves pain beneath the skin.
