What Is Peppermint Leaf Powder? Applications, Dosage, Alternatives & Specifications

Peppermint Oil, also known as Mentha Piperita Oil or Peppermint Essential Oil, is a natural volatile essential oil obtained by steam distillation from the aerial parts (mainly leaves and stems at flowering stage) of the perennial aromatic herb Mentha×piperita L., which belongs to the Lamiaceae family. It is an important category of natural flavors and plant extracts, with wide application value in the global food industry, pharmaceutical and healthcare sector, daily chemical products, and aromatherapy field. Its CAS number is 8006–90–4, FEMA number is 2848, and EINECS number is 616–900–7. In terms of chemical structure, peppermint oil is a highly complex multi-component natural mixture. Its main characteristic components are terpenoids, with key active ingredients including menthol (L-menthol), menthone, menthyl acetate, 1,8-cineole, limonene, and β-caryophyllene. Among these, menthol (L-menthol) is the primary component, responsible for its characteristic cooling sensation and refreshing aroma. Research indicates that peppermint oil obtained by hydro-distillation contains approximately 52.85% menthol, 25.93% menthone, and 8.59% 1,8-cineole; oil extracted by supercritical CO2 contains approximately 45.51% menthol, 27.3% menthone, and 8.92% 1,8-cineole. The extraction raw material for peppermint oil is Mentha×piperita L., a tetraploid hybrid species naturally derived from the crossbreeding of water mint (Mentha aquatica) and spearmint (Mentha spicata). It is widely distributed in Europe, the United States, India, and China. Commercial peppermint oil appears as a colorless to pale yellow or yellowish-green clear mobile liquid at room temperature, possessing a strong, refreshing, diffusive, and pleasant characteristic mint aroma. The initial taste sensation is warm, followed by a cooling feeling. Upon prolonged storage or exposure to light, the color gradually darkens and the viscosity increases. Peppermint oil exhibits multiple significant biological activities: first, menthol acts on the TRPM8 cold receptor on the skin and oral mucosa, producing a physiological cooling sensation; second, menthol has mild local anesthetic and analgesic effects; third, the terpenoid components in the oil possess good antibacterial, antifungal, and antiviral activities. By virtue of these unique physical and physiological properties, peppermint oil has become one of the most widely used and versatile essential oils in the global flavor and fragrance and plant extract market, and is often hailed as the “king of essential oils.”

Peppermint oil is recognized as the “king of essential oils,” holding an irreplaceable foundational position in the global daily chemical, food, pharmaceutical, and aromatherapy industries. Its most outstanding core advantages lie in its unique cooling physiological effect, excellent broad-spectrum biological activity, and extremely wide application adaptability.

Unique Cooling Physiological Effect: The core component menthol (L-Menthol) is one of the most representative cooling agents in nature. When peppermint oil acts on the oral cavity, skin, or mucous membranes, menthol selectively activates the TRPM8 cold receptor, producing a long-lasting, intense physiological cooling sensation without actually lowering the body temperature. This “pseudo-cooling” effect has unique application value in oral care products, analgesic topical preparations, and functional foods.
