Edible Uses

All violets are edible. The leaves and flowers can be eaten raw in salads, used as potherbs or thickeners, or made into tea. Violets are high in vitamins A and C. The flowers can be used as a garnish (fresh or candied) or as a flavoring and coloring in vinegar, jelly and syrup. When added to soup the leaves of early blue violet thicken it in much the same way as okra. A tea can be made from the dried leaves.

Medicinal Uses

Early blue violet was used medicinally mostly by the Blackfoot and Bella Coola Indians. An infusion of the leaves and roots has been used to treat stomach problems and asthma in children, and also as a wash and poultice on sore and swollen joints. The roots and leaves have been chewed by women during childbirth. A poultice of the chewed leaves was applied to sore eyes. A poultice of the crushed flowers was applied to the side or chest in the treatment of pain.

Poisonous Properties

The rhizomes, fruits and seeds are poisonous, causing severe stomach and intestinal upset, as well as nervousness and respiratory and circulatory depression.
