Last week I had the privilege of doing another interview on the subject of essential oils with Dr. Holly Lucille during her amazing Mindful Medicine show on RadioMD. I was really happy when Dr. Holly’s producer suggested peppermint oil to highlight because it has always been one of my favorite essential oils. As you can imagine, I totally geeked out researching peppermint’s various properties and uses.
BioChem Break (For Those Interested):
Peppermint oil contains mostly menthol menthone, menthyl acetate, menthofuran 1,8 cineol and pulegone. These compounds, in synergism with the essential oil, give peppermint a wide array of applications. These include use as a digestive aid, respiratory support, cognitive benefits, the creation of an unfriendly environment for viruses and bacteria, antioxidant activity, and more. Perhaps, though, it is most well-known for its efficacy in digestive complaints (1-13).
Peppermint Oil to the Digestive Rescue
Peppermint oil has been researched in vitro and in clinical trials for its efficacy in relieving digestive issues (1-13). In fact, a 2005 literature review of 16 different trials concluded that peppermint oil, may be a first choice option “in IBS patients with non-serious constipation or diarrhea to alleviate general symptoms and to improve quality of life.” (3)
Due to the fact that we can rub therapeutic and quality grade peppermint oil directly on our bellies, we don’t have to worry about messing with enteric-coated capsules of peppermint. As swallowing a pill at a time when digestion is acting up can be the last thing someone wishes to do. Furthermore, I’ve found with my clients that rubbing the oil on the belly prevents the side effect of heartburn from burping up the capsules.
Peppermint oil has also been also shown to calm spasms and to relieve functional disorders of digestion in the intestine and esophagus. (7-11) It also helps alleviate symptoms of colic in infants (12) and has been shown in some trials to assist with nausea. (13-14)
The MANY OTHER USES
1. Creating an unfriendly environment for viruses to thrive
Peppermint has demonstrated suppressive activity against the herpes virus in vitro and to may assist with dealing with postherpetic neuralgia pain. (15-17)
2. Respiratory support
Peppermint has expectorant properties (1,8 cineole which is an oxide) and may have antihistamine effects (18). Furthermore, one study showed, that when inhaled, it may help with exacerbations of symptoms associated with tuberculosis. (19)
3. Studied to prevent food born infections (20) and has anti-microbe properties (21)
1. I place 1 drop in 8 oz of water and sip it throughout the day. I alternate or combine it with my lemon to keep my belly happy and my mind clear, cheery, and focused.
2. I place 1 drop on my belly after eating out to prevent any digestive issues from unknown cross-contamination of food sensitivities.
3. I place 1 drop on my tongue (this is not for the weak) to freshen my breath and keep my mouth clean and my teeth strong!
Bonus: I’ve seen fevers drop with 1 drop peppermint mixed with a carrier oil on the bottom of little one’s feet.
