Abstract

Brahmi Rasayan, an Ayurvedic preparation, was studied in mice and rats for its effects on the central nervous system at oral doses ranging between 1 and 30 g/kg. Observational screening in mice was carried out following a multiparametric check list. The test material was studied for its effect on pentobarbitone hypnosis, motor co-ordination, tail-withdrawal reaction time, electroshock, chemoconvulsions, haloperidol-induced catalepsy and conditioned avoidance response. The test material exhibited a sedative effect and significantly prolonged the hypnotic action of pentobarbitone. It produced a variable blockade of conditioned avoidance response. The presence of a significant antinociceptive effect, coupled with the ability of the test substance to offer protection against electroshock seizures and chemoconvulsions plus the ability to antagonize the haloperidol-induced catalepsy, suggests an involvement of the GABA-ergic system in the mediation of the central nervous system effects of Brahmi Rasayan.
