Seems to help brain cells re-grow and repair themselves and it doubles as an antioxidant.

Bacopa has been revered for centuries in the Ayurvedic herbal tradition of India to enhance clear thinking and support memory function. Studies have shown that Bacopa supports learning and memory in humans. In animal models, Bacopa provides antioxidant protection for critical memory centers and helps to reduce the effects of stress on the brain. Traditional application suggests that Bacopa has a direct effect on improving brain functions, increasing concentration, and in promoting memory functions. Bacosides play a protective role in the synaptic functions of the nerves in the hippocampus, the seat of memory. Nerve impulses are transmitted across the synapses and their degeneration is believed to contribute to impaired memory and cognition.
