The repetitive administration of Centella asiatica further to
2 months showed the significant increase in %accuracy of both
numeric working memory and word recognition. In addition,
Centella asiatica also showed significant increase in reaction
time of both numeric working memory and spatial memory.
Thus, the present findings suggest that Centella asiatica can
improve both speed and accuracy of working memory. Since the
results showed the dissociation of temporal profiles in %accuracy
of numeric working memory and spatial memory reaction
time, thus, it was reasonable to suggest that the relationship
between the Centella asiatica treatment and working memory
following repetitive administration of this substance might not
be a simple relationship
