Historically, Menthol was sourced from mint (Mentha) plants of the Lamiaceae family, including wild mint (Mentha arvensis), horsemint (Mentha longifolia) and peppermint (Mentha × piperita). Mint plants are native to the Middle Eastern region, but various species currently thrive in parts of North America, South America, Europe, Asia, Africa and Australia. They typically favor moist soil and sun or partial shade. Mint plants have a bushy appearance and, depending on the species, may grow up to two feet tall.
Known for its powerful fragrance, mint is most often harvested for its leaves, which can be used to make the oil from which Menthol is produced. However, nearly every part of the mint plant — the flower, leaves, stems, seeds and bark — has been used by practitioners of traditional folk medicine to treat maladies including gastrointestinal disorders, pain, inflammation, fevers, insect bites, reproductive issues, mental health concerns and respiratory disorders. Mint was also an ingredient in oral care products, including an Ancient Egyptian toothpaste recipe dating back to the fourth century.
Mint is still wildly popular today, appearing in teas, ointments, digestive aids, skin care products, fragrances and other consumer goods.
