Peppermint Essential Oil 08-31-2016
Peppermint (Mentha × piperita, Lamiaceae) essential oil is steam distilled
from the partially dried herb or newly-harvested flower sprigs; the yellow to
olive green oil has a pungent, minty-green odor with a sweet, balsamic
undertone and a sweet, clean dryout note.1-3 Menthol, which produces
a cooling effect on the skin, is the main constituent, as well as menthone, a
ketone effecting wound healing and mucosal secretions.1
Considered one of the
most important essential oils, peppermint oil affects both mind and body with
its refreshing, cooling, stimulating, and uplifting characteristics.2
While peppermint oil has been used for a variety of conditions, it is most
often used as an expectorant, as well as for pain relief (migraine, sciatica)
and digestive issues (nausea, irritable bowel syndrome).1 However,
it has also been used to treat skin conditions such as acne, scabies, and
dermatititis.2 Therapeutic actions include analgesic, antiseptic,
antispasmodic, astringent, carminative, decongestant, hepatic, nervine,
sudorific, and vermifuge.3
One open-label study
that evaluated the efficacy of inhaled peppermint essential oil in patients who
experienced nausea after cardiac surgery found that a one-time use of the
inhaler resulted in 55.8% of the patients having no nausea and 23.5% having
only mild nausea.4 Five patients needed to use the inhaler a second
time, and four of them were nausea free after the second use. One randomized,
controlled trial measured the effects of Colpermin® (Tillotts Pharma
AG; Rheinfelden, Switzerland), containing 187 mg pH-dependent peppermint oil,
or Lactol® (BioPlus Life Sciences; Bangalore, India) capsules,
containing 150 million spores of Bacillus coagulans, on functional gastrointestinal
disorder symptoms in adolescent patients.5 Results showed that
Copermin reduced the patients' duration and severity of pain more than Lactol
or placebo. Essential oils are often used in concert together to enhance their
effects. A small, randomized, double-blind, controlled pilot trial tested the
effects of inhalation of peppermint, basil (Ocimum basilicum, Lamiaceae),
and helichrysum (Helichrysum italicum, Asteraceae) essential oils on symptoms of exhaustion and
burnout. Results demonstrated that, inhaled several times a day, this
combination of essential oils may help with the symptoms caused by exhaustion
and burnout.
