Brahmi (Bacopa monnieri) is a traditional herbal medicine that has been in use since the time of the Vedic civilization for cognitive problems. Today the prevalence of Alzheimer's disease among adults (almost 15% of adults of age 65 and above) and learning difficulties among children (between 5 to 15% among school going children) have grown exponentially high. As a result the usage of Ayush drugs related to adult and child psychological disabilities is getting more preference and among them Brahmi maintains its popularity as the most widely used brain tonic in the present era also.
