Just when you thought you’d seen the last of the unicorn beauty trend, here it is, creeping into 2018.

An ingredient called “true unicorn root,” otherwise known as Aletris farinosa, is showing up in beauty products. It’s an herb that grows in North America, and unfortunately, it’s neither sparkly nor particularly colorful. But like the mythical creature from which it takes its name, true unicorn root (not to be confused with false unicorn root) does seem pretty magical.

The herb ? specifically its underground stem, or rhizome ? is said to have been used by some Native Americans as a remedy for everything from stomach pain to colic and dysentery.
