Notes for this study:
In otherwise healthy older adults given _centella asiatica_ extract (3% polyphenolics and 5% asiaticoside plus asiatic acid) at 250-750mg once daily for up to two months, there were differential effects on reaction time (choice and spatial memory reaction time improved, simple and digit vigilance did not) after two months.

Working memory increased after 2 months in all groups, but after a single dose in the 250mg and 750mg groups; processing accuracy was unaffected and all parameters of mood were improved after two months with 750mg.
