Cereus Bonplandii is a plant belonging to the family of Cactaceae. It is a variety of Cactus grandiflorus (Cact). It is mostly erect, long stems of up to 3 m, 6 cm in diameter. The flowers are large and white, thornless, with brownish green outer petals, bloom at night and then are followed by an almost spherical red fruit, edible, containing black seeds. The remedy is prepared with the stem dye. It was proved by John H. Fitch from New Scotland, NY (Homeopathic Physician, 1892), in substantial doses. Cereus name seems coming from wax, a reference to candles, by its stem format.
