Bacopa plant shows promise for memory in research
Summary and headline written by AI from the source article. How we work
Researchers in Italy are re-examining Bacopa monnieri, a plant used for centuries in Ayurvedic medicine, to understand its effects on cognitive function.
Studies suggest the plant, containing compounds called bacosides, may improve the ability to recall information after weeks of consistent use. Several small clinical trials and reviews indicate positive effects on specific cognitive functions, particularly memory. One systematic review of six trials showed Bacopa improved free recall of information in healthy adults over a 12-week period.
A separate study with people 65 and older found that 300 milligrams of standardized extract daily for 12 weeks led to improvements in delayed memory and some cognitive measures. A meta-analysis of nine studies also pointed to possible benefits for attention speed. However, scientists note that Bacopa is not an immediate stimulant and its effects require time to become noticeable.
Research suggests bacosides may influence communication between neurons and protect nerve cells, but further study is needed to confirm these mechanisms in humans. A 2026 analysis confirmed the plant’s potential for improving memory, and researchers are now investigating whether it could play a role in slowing the progression of dementia, though current evidence is limited. While generally well-tolerated, Bacopa can cause gastrointestinal side effects like nausea and diarrhea.
