The present invention relates to use of herbal extracts for improved cognitive function, as well as food products having the extracts. A number of studies have, for example, identified positive correlations between childhood IQ, occupation, duration of education in early life, and cognitive function later in life. Various therapeutic agents have been prescribed for impaired cognitive function. We have determined that a combination of an extract of Terminalia chebula and Terminalia bellerica provides improved and synergistic expression of neuritis, with significantly lower toxicity.
