Ayurveda is the Science of Life.  It explains the nature of everything in the universe.  When it comes to learning, Ayurveda has a lot to say.  The ancient ayurvedic texts describe three aspects of mental ability.  The first is “dhi” which is the power of acquisition, or learning itself.  The second is “dhriti” which is the power of retention, how well we retain what we learn.  The third is “smriti” which is the ability to remember and recall what we have learned.  We need all three of these mental functions to be in balance and work with one another, or learning problems may arise.  Vatas tend to learn quickly, but then forget just as quickly.  Kaphas learn much more slowly, but they have an amazing memory for what they have learned.  Often AD/HD (Attention Deficit Hyperactivity Disorder) is an excess of Vata. Gotu kola (also known as the ayurvedic herb brahmi) is prized by students and yogis for its memory-enhancing properties.  Gotu Kola also promotes mental clarity and concentration.  It is an adaptogenic herb, which means that it helps to remove the negative effects of daily stress.
