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.

Analgesic;  Antiasthmatic;  Birthing aid;  Ophthalmic;  Poultice;  Salve.

An infusion of the leaves and roots has been used to treat stomach problems and asthma in children[257]. An infusion of the roots and leaves has been used as a wash and poultice on sore and swollen joints[257]. The roots and leaves have been chewed by women during childbirth[257]. A poultice of the chewed leaves has been applied to sore eyes[257]. A poultice of the crushed flowers has been applied to the side or chest in the treatment of pain[257].
Other Uses
Dye.

A blue dye can be obtained from the flowers[257].
Cultivation details
Prefers a cool moist well-drained humus-rich soil in partial or dappled shade and protection from scorching winds. Tolerates sandstone and limestone soils but becomes chlorotic if the pH is too high. Prefers a pH between 6 and 6.5[200]. All members of this genus have more or less edible leaves and flower buds, though those species with yellow flowers can cause diarrhoea if eaten in large quantities[62, 85, 159]. There is at least one named form selected for its ornamental value[200]. 'Alba' has white flowers[200]. Flowers formed late in the season are cleistogamous (lacking petals, the flowers do not open but are self-pollinated)[212].
Propagation
Seed - best sown in the autumn in a cold frame. Sow stored seed in early spring in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and plant them out in the summer. Division in the autumn or just after flowering. Larger divisions can be planted out direct into their permanent positions, though we have found that it is best to pot up smaller divisions and grow them on in light shade in a greenhouse or cold frame until they are growing away well. Plant them out in the summer or the following spring.

This is a very important larval host plant for the threatened Oregon Silverspot Butterfly (Speyeria zerene hippolyta). If you live on the coast of Oregon or Washington, please help protect areas where this plant grows, and plant some in your yard! I have been growing some in my yard and also have been looking for it in the wild areas around here (near 98607). I have found several that fit the description (blue, hooked spur) but have very different looking leaves and flower colors from each other so I'm a little confused as to the "real" viola adunca.
