Prickly Ash grows to height of 25 feet. In the spring the tree bears small, yellow-green flowers before the leaves appear. The plant has pinnate leaves and alternate branches which are covered with prickles. The plant bears red berries which grow in clusters and have an aromatic odour. Prickly Ash acts as a stimulant. It is used in chronic rheumatism, typhoid and skin diseases and to purify the blood. The berries have carminative and antispasmodic properties. They are used as an aperient and to cure dyspepsia and indigestion. The bark, when powdered acts as an excellent application to indolent ulcers and old wounds.
