Comptonia peregrina has been reported from Tennessee (Scott County), but I have not seen any specimens.
Many Native American tribes used different parts of Comptonia peregrina variously: as an incense for ritual ceremonies; for medicinal purposes; as a stimulant or tonic; as a food seasoning; and as a poison (D. A. Moerman 1986).
