Both Gotu kola (Centella asiatica and/or Hydrocotyle asiatica) and Bacopa monnieri are known as “brahmi.” Brahmi is a very important Ayurvedic herb, being particularly valued for its beneficial effect upon the nervous system. (1) In Ayurvedic medicine, bacopa is bitter and sweet and are especially good for pacifying pitta whilst also supporting vata and kapha. Bacopa monnieri is a nervine tonic used for enhancing cognitive function. It helps improve concentration, comprehension, recall and alertness.
Bacopa monnieri's main active constituents are steroidal saponins, including bacosides. (2) Several randomised, double-blind, placebo-controlled trials have substantiated Bacopa’s cognitive enhancing effects with Bacopa Minniera having the potential to improve cognition. (3) There is also evidence for potential attenuation of dementia, (4, 5) Parkinson's disease (6) and epilepsy. (7)
Current evidence suggests Bacopa acts via the following mechanisms—anti-oxidant neuroprotection (via redox and enzyme induction), acetylcholinesterase inhibition and/or choline acetyltransferase activation, β-amyloid reduction, increased cerebral blood flow, and neurotransmitter modulation (acetylcholine [ACh], 5-hydroxytryptamine [5-HT], dopamine [DA]).
