3.3. Cognitive measures
Prior to the determination of Centella asiatica on cognitive
function, baseline data and mean pre-dose raw baseline scores
for all four conditions (placebo, 250, 500 and 750 mg Centella
asiatica) for each individual task scores were subjected to a
one-way ANOVA. There were no significant differences on any
measure.
Mean pre-dose baseline raw scores and change from baseline
scores for each condition at each post-dose time point on
the individual task outcome measures are represented in Table 3.
The results showed that the Centella asiatica extract appeared
to decrease the reaction time while increased the %accuracy
of working memory, which indicated that the plant extract
exerted its influence on both speed and quality of working memory.
However, the significant changes in reaction times were
