Medicinal Uses
Plants For A Future can not take any responsibility for any adverse effects from the use of plants. Always seek advice from a professional before using a plant medicinally.
The root is diuretic, emetic, expectorant and mildly purgative[7, 9, 61]. Another report says that the juice of the fresh root is a strong purge of great efficiency in the treatment of dropsy[4]. In the past, sections of the dried root have been given to teething babies to chew on, though this has been discontinued for hygienic reasons[9]. Roots of plants 2 - 3 years old are dug up after flowering and are then dried for later use[7].

Other Uses
The root is a source of Orris powder which has the scent of violets[238]. It is obtained by grinding up the dried root[4, 7, 46]. It is much used as a fixative in perfumery and pot-pourri, as an ingredient of toothpastes, breath fresheners etc and as a food flavouring. The root can take several years of drying to fully develop its fragrance, when fresh it has an acrid flavour and almost no smell[4, 168]. An essential oil is obtained from the fresh root, this has the same uses as the root[57, 61]. The juice of the root is sometimes used as a cosmetic and also for the removal of freckles from the skin[4]. A black dye is obtained from the root[168]. A blue dye is obtained from the flowers[168].
