Waterhyssop (Bacopa monnieri), also known as Brahmi, has a long history of use in traditional Ayurvedic medicine for enhancing cognitive function and alleviating anxiety and stress. Recent scientific studies have begun to investigate these traditional claims. Several randomized, placebo-controlled trials and meta-analyses have suggested that Bacopa monnieri may exert anxiolytic (anxiety-reducing) effects. Its mechanisms are believed to involve modulation of neurotransmitter levels, particularly serotonin and dopamine, as well as antioxidant and adaptogenic properties that help the body manage stress.

For example, a 2014 systematic review (Calabrese et al., 2008; Kongkeaw et al., 2014) found moderate evidence that Bacopa supplementation could reduce anxiety and improve cognitive performance in adults. Animal studies also support these findings, showing reductions in anxiety-like behavior with Bacopa extracts. However, while the evidence is promising, most human studies to date have been small and of variable quality, and the effect sizes are generally modest. More rigorous, large-scale clinical trials are needed to fully validate Bacopa’s efficacy for anxiety disorders specifically.

In summary, there is scientific evidence—albeit preliminary and limited in strength—supporting the use of waterhyssop for anxiety. Its use is justified both by tradition and by a growing, though not yet definitive, body of scientific research.
