Haritaki for Cognitive Function

Research suggests that Haritaki (Terminalia chebula) may support cognitive function, though the current evidence base is limited to a single randomized, double-blind, placebo-controlled trial conducted in 2025. That study, which tested a standardized combination of Terminalia chebula and Boswellia serrata in adults aged 40 to 65 with self-reported memory complaints, found improvements in verbal learning, memory recall, visual learning, processing speed, and accuracy over 120 days, along with enhanced sleep quality and increased BDNF levels. However, because the supplement was tested as a blend rather than Terminalia chebula alone, it is not possible to isolate how much of the observed benefit can be attributed specifically to Haritaki. The authors themselves characterize the work as a proof-of-concept trial, meaning larger and more rigorous confirmatory studies testing Haritaki independently will be necessary before stronger conclusions can be drawn.
