Mentha piperita

Peppermint (Mentha piperita) is from the mint plant, which has over 25 different species, and is a natural hybrid cross between watermint (Mentha aquatica) and spearmint (Mentha spicata). Peppermint has been used in traditional folk medicines since ancient times, as a remedy for several conditions and illnesses. The chemical components of peppermint oil are menthol (40.7%), menthone (23.4%), as well as menthyl acetate, 1,8-cineole, limonene, beta-pinene and beta-caryophyllene.

Insect repellent
Peppermint is used against endoparasites in poultry in British Columbia. The oil has larvicidal activity against Aedes aegypti, Anopheles stephensi and Culex quinquegaasiatus mosquitoes.

Egg Quality
The addition of dry or fresh peppermint leaves to the diet of laying hens has been proven to significantly increase egg weight, egg production, egg mass, and feed intake.

Peppermint oil was found to be somewhat effective at reducing the number of Eimeria spp. which cause coccidiosis in chicken.

Vaccine enhancement
Peppermint oil is good for the protection of Newcastle disease-vaccinated chickens.

Mint has a fresh, slightly sweet and tangy fragrance with a strong menthol aroma.
