Peppermint properties


Peppermint is a very good digestive remedy

The beneficial properties of this plant for the digestive system have been praised since antiquity. Peppermint has been commonly used as other mints after meals to “settle” the stomach, avoiding flatulence, and helping digest food better. Specifically, the main properties are the following:

Carminative: Its content in carvacrol, thymol and menthol help expel excess gas from the intestine (Infusion of 1 tablespoon or twice of tender leaves in a litre of water. Take a couple of cups a day after hot meals.)

(Take capsules of peppermint oil specifically developed for the intestines available in pharmacies or stores. These capsules are designed to dissolve in the intestine instead of the stomach so that, when opened, in that part of the digestive tube they act directly in this area to help improve digestion and avoid the typical phenomena of flatulence or bloating related with malabsorption of fats)

Stomachic: Most antispasmodic properties are conferred by terpenes together with carvacrol, limonene and cineol. Menthol has soothing properties and has traditionally been seen as a good anti-emetic.

Besides avoiding vomiting after large meals, peppermint prevents spasms and increases the production of bile juices, so it generally facilitates digestion and dissolves or prevents cramping.

As is the case of chamomile, one should not exceed the recommended therapeutic doses or use this plant for too long because it can produce the opposite effect, leading to stomach irritation. (Infusion of a spoonful of dried plant per cup of water. Take a couple of cups a day.)

Choleretic: Peppermint, like other mints, has the ability to stimulate the liver by increasing the secretion of bile, so, it can be used to promote digestion. For regular use, it is best to choose this mint to pennyroyal (Mentha pulegium), which contains more pulegone and isopulegone than peppermint and may irritate the stomach if you prolong your treatment too much.

Relaxing for the intestines: The tannin content of this plant, the relaxing and antispasmodic properties of menthol as well as its soothing powers for the intestinal mucosa, can be profited to treat abnormalities associated with intestines.

Among the diseases that can be treated, we have the following: diarrhea, Crohn’s disease, irritable bowel syndrome, colitis, etc. (10 minutes infusion of a spoonful of dried plant. Drink two glasses a day)
