Bacopa monnieri is a medicinal herb used in Ayurveda, where it is also known as "Brahmi", after Brahma, the creator God of the Hindu pantheon. With the scientific name of Bacopa monnieri, this creeping, perennial herb has been praised in Ayurvedic and traditional medicines across the world for generations. It’s difficult to pinpoint an exact native for this wetland-growing herb and most experts agree that it has been growing in the wetlands of southern and Eastern India, Australia, Europe, Africa, Asia, and North and South America for hundreds of thousands of years. The best characterized compounds in Bacopa monnieri are dammarane-type triterpenoid saponins known as bacosides, with jujubogenin or pseudo-jujubogenin moieties as aglycone units. Other saponins called bacopasides I-XII have been identified more recently. The alkaloids brahmine, nicotine and herpestine have been catalogued, along with D-mannitol, apigenin, hersaponin, monniera sides I-III, cucurbitacin and plantainoside B. The constituent most studied has been bacoside A, which was found to be a blend of bacoside A3, bacopaside II, bacopasaponin C and a jujubogenin isomer of bacosaponin C. Brahmi contains bacopaside I (5.37%), bacoside A3 (5.59%), bacopaside II (6.9%), bacopasaponin C isomer (7.08%) and bacopasaponin C (4.18%). Previous research has shown that Brahmi exerts many pharmacological effects including memory boosting capacity in the treatment of Alzheimer’s disease and Schizophrenia, exhibiting antiparkinsonian, antistroke and anticonvulsant potentials. The present study discusses the chemical constituents of Brahmi along with in vitro and in vivo studies based on the pharmacological effects exerted by it. The efficacy of Brahmi in treating various disorders has evoked sufficient research in recent years and now it is a time to launch multiple clinical trials
