The name of various oleoresins allied to elemi; balsam is exuded by different species of trees found in East India, Africa, Brazil and Siberia. Our Balsam poplar is found in northern parts of the United States and Canada.

This tree attains a height of 50–70 ft., with a trunk about 18 inches in diameter. The branches are smooth, round and deep brown. The leaves are ovate, gradually tapering and dentate, deep-green above and smooth on both sides. In America the leaf buds are in bloom in April, and this is the official part and time for collection. They have an agreeable, incense-like odour and an unpleasant, bitterish taste. The balsamic juice is collected in Canada in shells and sent to Europe under the name of Tacamahaea.

The Populus balsamifera is generally confused with the Populus canadensis, from whose buds we get the virtues known as the Balm of Gilead; but it is much the superior tree for medical purposes.
