1. Peppermint Oil Can Treat Irritable Bowel Syndrome

Suffering from irritable bowel syndrome?

Irritable bowel syndrome refers to a medical condition affecting the colon or the large intestine.

The exact cause of this problem is unclear but some say that it’s due to the strong and long contraction of the intestinal walls, or abnormalities in the gastrointestinal system.

Peppermint oil can be an excellent remedy for this condition that causes abdominal pain, diarrhea, constipation, bloating and gas [2, 3].

Researchers from the University of Missouri-Columbia conducted a clinical trial involving 42 children diagnosed with irritable bowel syndrome [4].

The children were given either peppermint capsule or a placebo for two weeks [4].

Results show that 75 percent of the participants who received peppermint oil experienced less abdominal pain [4].

Other studies confirm that peppermint oil can be a viable treatment method for irritable bowel syndrome, not only for children but for adults as well [5, 6, 7, 8].

Herpes is a serious viral condition triggered by the herpes simplex viruses type 1 and 2 [9].

HSV-1 affects the face, mouth and throat while HSV-2 causes infection in the genital area [9].

The most common symptom of these conditions are red and inflamed blisters that turn into crusted ulcers over time [9].

In many cases, these blisters are accompanied by stinging pain, fever, swollen lymph nodes and headache [9].

The good news is, both types can be remedied with peppermint oil, thanks to its virucidal properties [10].

A 2003 study published in the Phytomedicine Journal reported that peppermint oil can actually stop the plaque formation of both viruses by up to 99 percent [11].

With the oil’s lipophilic nature, it can penetrate easily into the skin, and cause immediate effect [11].

Various studies confirm that peppermint oil has strong larvicidal effects that repel different mosquito species including those that carry diseases [15, 16, 17].

Researchers from India state that peppermint oil demonstrated “strong repellent action” against adult mosquitoes after topical application [15].

They discovered that inhalation of both essential oils significantly reduced anxiety levels [23].

If peppermint oil worked just as well as lavender, then it means that it’s also very effective.
