The Florentine Codex, Book 11, folio 141v-142r, includes a plant called xonecuilpatli (which would also be spelled xonecuilpahtli with the glottal stop). This plant is the source of a remedy for gout in the form of a beverage. It can also be rubbed onto the body. The plant can sting like a scorpion bite. One who is paralyzed can be cured by taking a bath in the infusion. Incidentally, the image of the plant suggests nothing twisted or bent, so the origin of the name is unclear.
