It is a popular ornamental plant, kept for its large, showy flowers.
Mesembrine is an alkaloid present in Sceletium tortuosum (kanna). It has been shown to act as a serotonin reuptake inhibitor (Ki = 1.4 nM), and more recently, has also been found to behave as a weak inhibitor of the enzyme phosphodiesterase 4 (PDE4) (Ki = 7,800 nM). Still more recently, in an in vitro study published in 2015, scientist concluded that "a high-mesembrine Sceletium extract exerts its anti-depressant effect by acting primarily as monoamine releasing agent, rather than as selective serotonin-reuptake inhibitor." As such, mesembrine likely plays a dominant role in the antidepressant effects of kanna. The levorotatory isomer, (−)-mesembrine, is the natural form.
Veratrum album, the false helleborine, white hellebore, European white hellebore, or white veratrum is a poisonous plant in the family Melanthiaceae. It is native to Europe and parts of western Asia.

Tabernaemontana divaricata, commonly called pinwheel flower, crape jasmine, East India rosebay, and Nero's crown, is an evergreen shrub or small tree native to South Asia, Southeast Asia and China. In zones where it is not hardy it is grown as a house/glasshouse plant for its attractive flowers and foliage. The stem exudes a milky latex when broken, whence the name milk flower.
