Description:
Sweetgums are notable for their sharply pointed leaves and ornament-like, spiky fruit. While sweetgum balls are atmospheric when looking up at them dangling from leafless branches in the fall and winter, they are less romantic once they have hit the ground. When scattered across sidewalks or hidden in lawns, they are more likely to call to mind medieval flails.
The origin of sweetgum’s common name is quite literal; its sap was once collected, allowed to harden, and used as a chewing gum. Sweetgum is a tree of Special Concern in Connecticut.

-20 - 30 F

Ethnobotanical Uses:
The Cherokee, Choctaw, Koasati, Rappahannock, and other Native American tribes used the hardened sap of this tree as a chewing gum. Tea was made from the fruit and the bark.
Medicinal / Pharmaceutical:
Some Native Americans made a salve from this tree to apply to wounds, cuts, sores, bruises, and ulcers. Roots could be made into a strong tea to treat skin sores. Some of the sap could be taken before meals to reduce fevers, and the sap and inner bark were used to treat diarrhea and dysentery. Bark could be used in making a sedative for nervous. The tree was also used to treat colic and internal diseases.
