Mentha piperita herb and plant, extract and oil of peppermint health benefits

Mentha piperita is one of the most widely consumed single ingredient herbal teas, or tisanes. Mentha piperita tea, brewed from the plant leaves, and the essential oil of peppermint are used in traditional medicines. Evidence-based research regarding the bioactivity of this herb is reviewed. Few human studies of Mentha piperita leaf supplements have been done.

Composition
The phenolic constituents of the Mentha piperita leaves include rosmarinic acid and several flavonoids, including eriocitrin, luteolin and hesperidin. The main volatile components of the Mentha piperita essential oil are menthol and menthone.

The antioxidant activities and the determined major components of six popular and commercially available herb essential oils, including lavender (Lavendular angustifolia), peppermint (Mentha piperita), rosemary (Rosmarius officinalis), lemon (Citrus limon), grapefruit (Citrus paradise), and frankincense (Boswellia carteri), were compared. The essential oils were analysed by GC-MS and their antioxidant activities were determined by testing free radical-scavenging capacity and lipid peroxidation in the linoleic acid system. The major components of the essential oils of lavender, peppermint, rosemary, lemon, grapefruit, and frankincense were linalyl acetate (28.2%), menthol (33.4%), 1,8-cineole (46.1%), limonene (64.5 and 94.2%), and p-menth-2-en-ol (34.5%), respectively. The highest DPPH radical-scavenging activity was obtained by the lavender essential oil and limonene, with RC50 values of 2.1 +/- 0.23% and 2.1 +/- 0.04%, respectively. Radical-scavenging activity against the ABTS radical was highest in peppermint essential oil. Lavender oil was most effective for inhibiting linoleic acid peroxidation after 10 days.
