Menthol’s Cool Sensation Comes Straight from Mint Leaves
Menthol is a natural compound found in the oils of mint plants like peppermint and corn mint. It’s well-known for creating a lasting cooling sensation on the skin or in the mouth, which is why it’s a popular choice in both refreshing supplements and topical products. This cooling effect happens because menthol interacts with cold-sensitive nerve receptors.
