Ingredient:
Menthol
What it is:
Menthol can be synthetically made or derived from some form of mint oil. Ours is naturally derived from Mentha arvensis (wild mint) and Mentha x piperita (peppermint) leaves. Essential oil is extracted from the leaves using steam distillation, then it’s frozen to convert it to ice crystals, and then dried to produce menthol crystals.
What it does:
Menthol has been used by people since ancient times, but only recently did scientists uncover how it works (1). It naturally triggers cold-sensitive receptors in the skin to create a cooling, refreshing sensation whether it’s applied to the skin, eaten, or inhaled (1-5).
Why we use it:
We love to source ingredients directly from nature that take relatively little processing to create a raw material for commercial purposes. Menthol’s natural cooling and refreshing properties make it a perfect addition to our Mouthwash and Organic Shave Oil.
