Peppermint
Also known as: Menthol, Mentha piperita, Mentha balsamea
Overview
Peppermint (Mentha piperita) is a plant which is a hybrid from watermint and spearmint, used initially for culinary and food manufacturing purposes but has also been used for its supposed medicinal benefits. Peppermint has an oil component which appears to be its medicinal component, and this oil has a very large content of menthol which is seen as its bioactive ingredient. This menthol is nontoxic at the recommended dose, but is the same menthol also found in some cigarette products. The main medicinal role of peppermint is due to its muscle relaxing properties in the stomach and intestinal tract, and internal usage of peppermint appears to be able to speed up the early phase of digestion in the stomach while reducing colonic motility. It is known as a carminative agent (thought to relief flatulence), and it has a fair bit of evidence to supports its usage in reducing abdominal pain in persons with irritable bowel syndrome (IBS). It doesn't seem to influence other symptoms of IBS too much, but the reduction of abdominal pain is quite notable. Other possible benefits of peppermint oil include fast headache relief (which involves applying a topical solution of 10% peppermint oil to the scalp at the onset of a tension headache) and possibly a reduction in nausea when used as aromatherapy. It is safe with the recommended dosages, but overconsumption of peppermint oil supplements does have a toxic level which is feasible to reach intentionally.
Benefits
Peppermint oil works primarily through its active component, menthol, which has muscle relaxing properties. When ingested, peppermint oil can help relax the muscles of the gastrointestinal tract, which may aid in digestion and reduce symptoms of gastrointestinal discomfort. It is thought to speed up the early phase of digestion in the stomach while also reducing colonic motility, which can help alleviate symptoms associated with irritable bowel syndrome (IBS). Additionally, when applied topically, peppermint oil can provide relief from tension headaches by relaxing the muscles in the head and neck area.
How it works
Peppermint offers several benefits, including: 1. **Digestive Health**: It is known to relieve symptoms of irritable bowel syndrome (IBS), particularly abdominal pain. 2. **Headache Relief**: Topical application of peppermint oil can provide fast relief from tension headaches. 3. **Nausea Reduction**: Aromatherapy with peppermint oil may help reduce feelings of nausea. 4. **Carminative Effects**: It can help relieve flatulence and improve overall digestive comfort.
Side effects
Oral supplementation of peppermint oil for the purpose of gastrointestinal health and motility involves consuming anywhere between 450-750mg of the oil daily in 2-3 divided doses, and this is around 0.1-0.2mL of the oil itself per dosage. The exact optimal dosage of peppermint is not known, and the numbers reflect a menthol content somewhere between 33-50%. Usage of peppermint for the treatment of headaches involves having a solution of 10% peppermint oil and applying a relatively thin layer to the front of your head upon the start of a headache, with another application after 15 minutes and 30 minutes (for three applications in total). Usage of peppermint for aromatherapy does not follow any particular dosing, and similar to other forms of aromatherapy it should be used as either an oil or in a distiller until a pleasant aroma permeates the vicinity. Any form of peppermint oil should be effective although for persons who experience heartburn (acid reflux) and wish to supplement with peppermint oil for their intestines, then an enteric coated capsule would be useful (since the muscle relaxing effects may affect the esophagus if the capsule breaks prematurely).
Dosage
Peppermint oil is generally safe when used at recommended dosages. However, overconsumption can lead to toxicity. Some individuals may experience side effects such as heartburn, allergic reactions, or gastrointestinal discomfort. It is advised that individuals with gastroesophageal reflux disease (GERD) or those who are pregnant consult a healthcare provider before using peppermint oil.
