Brahmi supports the mind and nervous system, helping to improve memory and sustain intellectual effort. The leaves are considered to be very sattvic, i.e., pure as opposed to dull or stimulating. Gotu kola aids restful sleep and is a natural blood purifier. It was used by Machamuni Siddhar for his kalpa. In a way, brahmi is tridoshic because it reduces excess vata in the mind, is cooling to pitta, and decongesting to kapha.
