Nonochton is the Classical Nahuatl name for a plant whose identity is uncertain. Suggested plants include Portulaca, Pereskiopsis,[1] and Lycianthes mociniana, a plant now called tlanochtle in the local variety of modern Nahuatl spoken by highland farmers that cultivate it for its fruit.[2]
In Aztec medicine, nonochton was used as an ingredient in a remedy for pain at the heart:
For him whose heart pains him or burns, take the plant nonochton that grows near an ants’ nest, gold, electrum, teo-xihuitl, chichiltic tapachtli and tetlahuitl, with the burned heart of a deer, and grind them up together in water; let him drink the liquor.
