The seeds contain hypoglycin A, a protoxin that can cause seasonal pasture myopathy (SPM) in horses. The pollen is highly allergenic.
The wood has been used for various decorative applications, such as turned items (bowls, stem-ware, pens). It has also been used by Native Americans for making tubes for bellows, bowls, drums, and pipe stems. The sap has been used to make syrup by various Native American tribes.
