Long-leaved phlox was used medicinally by several native tribes, the Havasupai, Okanagan-Colville, the Paiute, the Shoshoni and Washo Indians among others. A decoction of pounded roots was rubbed all over the body for colds or aches, it was also given to babies with stomachaches. An infusion of the whole plant was given to "anemic" children. An infusion of mashed roots was taken for diarrhea. A decoction of the entire plant was taken for stomach disorders, and an infusion of roots was given to children for stomachaches. Externally, a decoction of leaves was put on boils, and an infusion or decoction of roots was used as an eyewash.
