According to Greek mythology, a rainbow ("iris" in Greek) would appear when Goddess Iris—the Olympian messenger—would open communications between heaven and earth. Iris grows in the wild, but is also cultivated for the cosmetics industry. Upon drying, its root gives off a very pleasant aroma similar to the scent of violets, and it is used as an ingredient in many perfumes. In olden times, doctors would recommend it to relieve children's coughing and teething pains.
In cosmetics, Iris Root extract is a natural astringent that helps balance oily skin.
