Ratibida columnifera
Plains coneflower used by Lakota, Cheyenne, and Blackfoot for headache, fever, and skin conditions.
Ratibida columnifera (prairie coneflower) is a perennial herb traditionally used by Plains tribes for headache, fever, and wound healing. Its primary active compounds include sesquiterpene lactones (e.g., ratibidiol), flavonoids, and tannins, which contribute to anti-inflammatory, analgesic, and antipyretic effects. Modern evidence is limited to preliminary studies, supporting its traditional applications but warranting further clinical investigation.
Sesquiterpene lactones in Ratibida columnifera inhibit the NF-κB pathway, reducing pro-inflammatory cytokine production and COX-2 expression, thereby exerting anti-inflammatory and analgesic effects. Flavonoids provide antioxidant activity by scavenging free radicals and modulating Nrf2 signaling, while tannins contribute to astringent and wound-healing properties through protein precipitation and antimicrobial action. Antipyretic effects may involve central prostaglandin inhibition via COX-2 suppression in the hypothalamus.
