Description

Extracted from the stem, leaves, and flowers of Mentha piperita L. plant, peppermint oil (Mentha piperita) is a popular essential oil used in aromatherapy for both external and internal use. Mentha piperita is a hybrid of spearmint (Mentha spicata) and water mint (Mentha aquatica) ⁶. Medicinal use of herbal ingredients such as peppermint oil has a long history of treating digestive disorders and upper respiratory symptoms and cough ². There are various over-the-counter and commercial uses of peppermint oil due to its carminative, cholagogue, antibacterial, secretolytic, and choleretic actions ³. Peppermint oil contains pulegone, which is a naturally-occurring pesticide ⁷. Other active constituents of peppermint oil include Menthol, menthone, cineol, and several other volatile oils ^2,3.

Peppermint oil is used as a flavouring agent in foods and fragrance in hygienic or cosmetic products, and as an anti-itch and cooling agent in topical pharmaceutical products. It is also an active ingredient in topical analgesics for the relief of joint and muscle pain. Peppermint oil can be applied topically to temporarily relieve tension-type headache. The use of peppermint oil in the management of irritable bowel syndrome (IBS) has been investigated in many clinical studies due to its relaxing effects on smooth muscle; however the evidence supporting this use is unclear. Due to its effectiveness in relaxing GI smooth muscle but ability to induce gastroesophageal reflux, enteric-coated formulations of peppermint oil has been established which bypass the upper GI tract unmetabolized, thereby facilitating its effect in the lower GI tract without effects in the upper tract ². Peppermint oil is safe and well-tolerated at commonly recommended dosage ².

-the temporary relief of itching associated with insect bites, eczema, minor burn, sunburn, minor skin irritations, minor cuts, scrapes, atopic dermatitis and other skin disorders.

-the temporary symptomatic relief of mild joint and muscle pain as a local topical analgesic.

Pharmacodynamics

Peppermint oil induces a dose-related antispasmodic effects on the gastrointestinal smooth muscles ³. A meta-analysis study and additional clinical studies of patients with IBS demonstrated that the treatment with peppermint oil improves abdominal symptoms compared to the placebo group, resulting in reduced severity of abdominal pain, decreased abdominal distension, reduced stool frequency, and reduced flatulence ^2,4. The use of enteric-coated peppermint oil was shown to be effective in reducing gastrointestinal symptoms of non-ulcer dyspepsia ². In rats, peppermint oil promoted a time-dependent choleretic effect in increasing bile production and biliary output ³. In randomized controlled trials, topical application of peppermint oil was associated with a significant analgesic effect and a reduction in headache intensity compared to placebo ². In a study of C57BL/6 mice, topical application of peppermint oil for 4 weeks was associated with a prominent hair growth effects; a significant increase in dermal thickness, follicle number, and follicle depth ¹.

Mechanism of action

Dose-dependent antispasmodic effect of peppermint oil is largely mediated by its menthol constituent ³. It is proposed that peppermint oil relaxes gastrointestinal smooth muscle and attenuates contractile responses by reducing the influx of extracellular calcium ions. In rabbit jejunum smooth muscle cells investigated via whole cell clamp configuration technique, peppermint oil was shown to inhibit the potential-dependent calcium currents in a concentration-dependent manner ³. Both a reduction in peak current amplitude and an increase in the rate of current decay were observed, indicating that the pharmacological activity peppermint oil resembles that of dihydropyridine calcium antagonists ³. In a rat small intestine study, peppermint oil in the intestinal lumen inhibited enterocyte glucose uptake via a direct action on the brush border membrane and inhibited intestinal secretion ³. There is also evidence that menthol is an antagonist of L-type Ca2+ channels via interacting with dihydropyridine binding sites and blocks the currents of low-voltage-activated calcium channels ³. Peppermint oil may facilitate hair growth by promoting the conservation of vascularization of hair dermal papilla, which may contribute to the induction of early anagen stage of active growth phase of hair follicles ¹.

Absorption

After oral administration, peppermint is rapidly absorbed ³. Menthol is highly fat-soluble therefore rapidly absorbed from the proximal gut ⁵.

Volume of distribution

No pharmacokinetic data available.

Protein binding

No pharmacokinetic data available.

Metabolism

The predominant biliary metabolite of peppermint oil is menthol glucuronide, which undergoes enterohepatic circulation ³. The urinary metabolites are products of hydroxylation at the C-7 methyl group at C-8 and C-9 of the isopropyl moiety, forming a series of mono- and dihydroxymenthols and carboxylic acids, some of which are excreted in part as glucuronic acid conjugates ³.

Route of elimination

Peppermint oil is eliminated mainly via the bile following oral administration, with glucuronide and sulphate metabolites predominant ³. The metabolites, mainly menthol glucuronide and mono- or di-hydroxylated menthol derivatives, may also undergo approximately equal renal and fecal excretion ³. Renal recovery of total menthol within 24 hours was dose-dependent whereas the recovery in bile was substantially higher over 8 hours ³.

Toxicity

Oral LD50 value in rat is 2426 mg/kg ^MSDS. In fasted mice, the LD50 following oral administration was 2410 mg/kg ⁷. Higher doses of peppermint oil has the potential to induce menstruation, bronchospasm, tongue spasms, and, possibly, respiratory arrest ² in addition to potential hepatotoxicity and nephrotoxicity ⁶.

Overdose may cause severe gastrointestinal symptoms, diarrhoea, rectal ulceration, epileptic convulsions, loss of consciousness, apnoea, nausea, disturbances in cardiac rhythms, ataxia and other CNS problems, probably due to the presence of menthol ⁸. In the event of overdose, the stomach should be emptied by gastric lavage. Observation should be carried out with symptomatic treatment if necessary ⁸. A near fatal case of high dose peppermint oil ingestion was reported, the overdose was characterized by comatose and reduced heart rate ⁶.
