Spearmint Essential Oil

Spearmint (Mentha spicata) is a species of mint that is originally native to Europe, and named after the pointed shape of its leaves.

Compared to its counterpart peppermint, spearmint has a much lower menthol content, giving spearmint a milder, sweeter flavor and scent—great for food, beverages, and candy. Spearmint is also used in personal hygiene products like toothpaste, soap and shampoo.

Spearmint essential oil is made by steaming the spearmint plant and distilling the extracted oil, a process known as steam distillation. This oil has a pleasant minty scent, similar to, but less harsh than, peppermint essential oil.

Spearmint essential oil has traditionally been used for aromatherapy, creating homemade massage oils and oral hygiene products. In recent years, researchers have noted its antimicrobial and antioxidant properties, indicating its therapeutic benefits.

Benefits of Spearmint Essential Oil

Preliminary evidence has observed that spearmint essential oil can inhibit the growth of microbes, help relieve nausea, and may defend cells against potential harmful free radicals.  The benefits of spearmint essential oil are:

  1. Antimicrobial Properties
  2. Antioxidant Properties
  3. Nausea Relief Benefits
  4. Respiratory Problems & Treatment Benefits

Antimicrobial Benefits of Spearmint Essential Oil

Spearmint essential oil inhibits the growth of at least five types of pathogenic fungi and four strains of pathogenic bacteria, including Staphylococcus aureus, which causes skin infections.This means that applying diluted spearmint oil to your skin may ward off or clear up skin infections caused by bacteria or fungi.

Antioxidant Properties of Spearmint Essential Oil

An antioxidant is a compound that stops free radicals from doing damage to the body. In a 2006 clinical study, researchers noted that one of the main components of spearmint essential oil, S-Carvone, is a powerful antioxidant.4

The data from laboratory test noted that S-carvone demonstrated higher antioxidant levels than α‐tocopherol (a form of vitamin E). This means that spearmint essential oil may help to prevent free radical damage. Further research is required to confirm these findings and establish how if these benefits could translate to inhalation or topical applications.

Nausea Relief Benefits of Spearmint Essential Oil

A 2013 study investigated spearmint essential oil as a therapeutic tool for nausea in patients undergoing chemotherapy. Patients who took two drops of spearmint essential oil in a specially designed capsule reported less severe nausea, and vomited fewer times, on average, than patients who took a placebo capsule.5

While this data is promising, further research is still required to establish the efficacy and safety of using spearmint essential oil to reduce symptoms of nausea. Spearmint essential oils should not be used to replace conventional cancer treatments or anti-nausea medications.  It is not recommended to consume spearmint essential oil orally, unless under the direct supervision of a health care professional.
