Brahmi has been used since ages for the treatment of the following diseases.

Brahmi is renowned in Ayurvedic medicine for the proper growth of hair. Its antioxidant properties allow the proper nourishment to reach the hair roots and thus promote their growth.

Perhaps the most major use of brahmi is in the treatment of several mental problems in humans. Taken on a regular basis, brahmi helps to increase the concentration of humans and improves their memory and retention capacity. It is believed that consecrating children with brahmi oils gives makes them into intelligent individuals. Regular use of the brahmi oil is effective in treating mental imbalances, emotional disturbances and also in the prevention and cure of geriatric mental problems such as amnesia and Alzheimer's. Brahmi vati, an important Ayurvedic preparation containing brahmi along with jatamansi (muskroot) and serpagandha (rauwolfia) is used as a brain tonic.
