Abstract
Various parts of the tropical plant Morinda citrifolia L. (noni) have been widely used in traditional medicine in South and Southeast Asia for several centuries. The therapeutic effects of noni are believed to be mediated through several groups of phytochemicals such as anthraquinones, iridoids, fatty acid glycosides, alcohols, flavonoids, triterpenes etc.
Though a large number of in vitro and in vivo animal studies demonstrated a range of pharmacological effects, clinical data are essentially lacking. Current evidence suggests that Morinda citrifolia beneficially affects also the nervous system-several studies have demonstrated anxiolytic, antidepressant, neuroprotective and memory-enhancing effect.
Some mechanisms of action were already explained and next research continues.
