Iris × germanica is the accepted name for a species of flowering plants in the family Iridaceae commonly known as the bearded iris.

Historically, orris root was highly prized in the perfume industry. The root develops a pleasant violet-like scent when it dries. This scent continues to improve in storage, reaching its peak in about three years. Orris root was widely used in face powders and other cosmetics until people noticed it was causing allergic reactions. Orris root powder is still used extensively in potpourris, sachets, and pomanders.

Orris root is used for “blood-purifying,” “gland-stimulating,” increasing kidney activity, stimulating appetite and digestion, and increasing bile flow. It is also used for headache, toothache, muscle and joint pain, migraine, constipation, bloating, diabetes, and skin diseases.

Some people use orris root to treat bronchitis, colds, cancer, back pain caused by the sciatic nerve (sciatica), and swelling (inflammation) of the spleen. It is also used to cause vomiting, empty the bowels, and promote calmness.

Orris root is sometimes applied directly to the affected area for bad breath, nasal polyps, teething, tumors, scars, muscle and joint pain, burns, and cuts.
