I remember hiking into Tiger Creek Preserve, near Lake Wales, during a scorchingly hot late September day. I forgot my water, and was parched. But my heart was filled with happiness when I saw a few hundred of these native pink-flowered beauties in full bloom. There were nectaring butterflies in abundance, and I walked slowly through them all. There were Gulf Fritillaries, Eastern Tiger Swallowtails, various Skippers, and more... what a sight. According to Daniel Austin, in his encyclopedic book Florida Ethnobotany, this species is a urinary antiseptic that was sold under the proprietary name Rasapen.
MEDICINAL USES: Roger Hammer writes, “Leaf extracts werecombined with horseradish as a urinary antiseptic drug called Rasapen.” Rasapen is a "urinary antiseptic drug." According to Daniel Austin in his encyclopedic book Florida Ethnobotany, it was this very this species that is a urinary antiseptic and was sold under the proprietary name Rasapen. Also, ActaChemaScandinavica published an article entitled “Volatile constituents of Carphephoruscorymbosus and Carphephoruspaniculatus.” by Karlsson K, Wahlberg I, EnzellCR. 
WILDLIFE: Craig Huegel writes, “few wildflowers in Florida attract butterflies as well as Florida Paintbrush.” “Attracts many butterflies and other pollinators.”
