Edible Uses:
The fruit of choke cherry is edible, raw or cooked. Very harsh, it is normally used in pies, jellies etc. Dark and juicy, it is sometimes edible raw when fully mature. The seed can contain high concentrations of hydrogen cyanide, a poison that gives almonds their characteristic flavor. This toxin is readily detected by its bitter taste. It is usually present in too small a quantity to do any harm, any bitter seed or fruit should not be eaten. In moderate to larger quantities hydrogen cyanide can cause respiratory failure and even death. The bark and twigs can be used as a tea substitute.

Medicinal Uses:
The roots and the bark of chokecherry are a blood tonic, astringent, sedative, tonic and appetite stimulant, and has agents that relieve disorders of the chest and lungs, as an expectorant. Chokecherry has been used medicinally by many native peoples. The inner bark bark of the limbs, trunk and root are all very useful and contain the same medicinal properties, although the root is always better. Wild cherry is an herb which has been used for a very long time in herbalism and is mostly noted for its use in respiratory problems. It has a soothing and sedative effect on the nervous system. It is in this way that it has its influence on the heart. In digestive disorders its use is very noticeable. It helps the flow of gastric juices. This is very helpful in conditions of dyspepsia. In respiratory affections wild cherry soothes the cough and at the same time gives tone and strength to the system. Externally, the bark can be placed in water for a few days in part sun and then used with advantage for pink eye and other infections of the eye.

Toxic Properties:
New growth, wilted leaves, or plant parts that are injured by frost or drought are poisonous to cattle and humans. The toxin, hydrocyanic acid, is formed in the animals stomach. Hydrocyanic acid quickly affects animals and causes difficulty in breathing, slow pulse, dilated pupils, staggering and loss of consciousness before death. Chokecherry toxicity is highest during the spring and summer; however, leaves are non-toxic by the time fruits mature. Children have been poisoned and have died after ingesting large quantities of berries, which contain the seeds.

Other Uses:
The plant forms thickets by means of suckers from its extensive root system and can be planted for erosion control. It is a pioneer species of abandoned fields and cut-over lands. A green dye can be obtained from the leaves.
