1. Irritable Bowel Syndrome (IBS)
Peppermint oil capsules have been described as “the drug of first choice” in IBS patients, as it safely helps alleviate symptoms and improve quality of life.

Peppermint oil is an effective alternative to drugs like Buscopan for reducing colonic spasms. It may also relax the muscles of your intestines, allowing gas to pass and easing abdominal pain. Try peppermint oil or leaves added to tea for gas relief.
3. Gastric Emptying Disorders
In people with functional gastrointestinal disorders, peppermint may be useful to enhance gastric emptying.
4. Functional Dyspepsia (Upset Stomach and Indigestion)
Supplementing with 90 milligrams (mg) of peppermint oil, along with caraway oil, “much or very much improved” symptoms of functional dyspepsia in 67 percent of patients. If you have an upset stomach, try drinking a small glass of water with a few drops of peppermint essential oil added.

Powdered peppermint leaves have also been used historically to freshen breath and whiten teeth; you can even add a drop or two directly to your toothpaste.
16. Respiratory Benefits
Peppermint oil acts as an expectorant and decongestant, and may help clear your respiratory tract. Use peppermint essential oil as a cold rub on your chest or inhale it through a vaporizer to help clear nasal congestion and relieve cough and cold symptoms.
Peppermint oil may help relieve tension headache pain. For headache pain, try dabbing a few drops on your wrist or sprinkling a few drops on a cloth, then inhaling the aroma. You can also massage the oil directly onto your temples and forehead.
Peppermint oil is cooling and energizing. Add a few drops to your bath, or dap a few drops directly on your body then get into the tub, for near-instant stress relief. You can also put the oil into a burner for a stress-relieving aroma.
19. Hair and Skin
Try blending peppermint oil into your massage oil, shampoo, bodywash or body lotion. It has antiseptic and antibacterial properties that can help cool your skin and remove dandruff (and lice) from your scalp.
Peppermint contains rosmarinic acid (also found in rosemary), which may help to reduce inflammation-causing chemicals in people with asthma.
