The Comanches held the plant in such high regard that they would make offerings to it during harvesting. They would take the latex and use it to remove warts, treat cold sores and other skin problems. A concoction could also be made from the flower to treat congestion from the cold or the flu. The seeds can also be used as an emetic to induce vomiting or as a laxative or even as a mild sedative. The entire plant can also be used to treat bladder infection, prostate pain, or to help the throbbing pain of a migraine. A wash made from the tea can also be used to help heal sunburns or scraped skin. The plant is also smoked during some important ceremonies to induce a euphoric and mild sedating effect. However, if not used properly, the plant can be very toxic.
