Orris root (Rhizoma iridis; etymology possibly an alteration of iris) is the root of Iris germanica and Iris pallida. It had the common name of Queen Elizabeth Root.[1] It is commonly used as a fixative and base note in perfumery and as a botanical in gin.
Uses
Once important in western herbal medicine, it is now used mainly as a fixative and base note in perfumery; it is the most widely used fixative for potpourri.[3] Orris is also an ingredient in many brands of gin,[4] including Bombay Sapphire.[5]
Fabienne Pavia, in her book L'univers des Parfums (1995, ed. Solar), states that in the manufacturing of perfumes using orris, the scent of the iris root differs from that of the flower. After preparation the scent is reminiscent of the smell of violets.[3]
In Japan, the roots and leaves of the plant were hung in the eaves of a house to protect the house and occupants from attacks by evil spirits. Other magic uses include using it as a love potion, with the root powder in sachets, or sprinkled around the house or sheets of a bedroom.[1]
