It is a base note that is used in perfumery and is also an ingredient in certain brands of gin.
Orris Root is used in coughs, bronchitis, stomach pain, and in biliary and liver diseases. Orris root is a mild diuretic and anti-inflammatory that has been used to treat sore throats and sinus headaches.
The odorous constituent of oil of Orris is a liquid ketone named Irone, to which the violet-like odour is due (though it is not absolutely identical with oil of Violets obtained from the natural flower), and it is the presence of this principle in the rhizome that has long led to the employment of powdered Orris root in the preparation of Violet powders, which owe very little of their scent to the real Violet perfume.
The dried powder is said to act as a good snuff, useful to excite sneezing to relieve cases of congested headache.
