Because recent molecular studies, based on multiple data sets from all three plant genomes, have indicated mutually congruent, well-resolved, and well-supported relationships within Convolvulaceae (the morning-glory family), a formal reclassification of this family is presented here. Convolvulaceae, a large family of worldwide distribution, exhibiting a rich diversity of morphological character...

BR-16A is a herbal (non-allopathic) medication used in India to enhance cognition in this study. Wistar rats (n=24) received either BR-16A (200 mg/kg/day) or vehicle alone for 3 weeks. Over 4 consecutive days during the third week, the rats were tested for learning in the Hebb Williams complex maze. BR-16A treated rats showed significant learning while controls did not. It is concluded that BR-...

The effectiveness of BR-16A, a herbal psychotropic preparation, was investigated in shortterm memory paradigms in mice. The passive avoidance task consisted of an electric grid with a centrally located shock-free zone (SFZ). BR-16A (50-500 mg/kg) improved passive avoidance acquisition as well as retrieval in mice. BR-16A reversed scopolamine (0.3 mg/kg)-induced disruption of learning and memory...

Subchronic administration of BR-16A (Mentat), a compound herbal formulation, and the nootropic agent, piracetam, augmented learning acquisition and retention of learning in normal rats, as well as in states of cognitive deficits induced by prenatal undernutrition, postnatal environment impoverishment and sodium nitrite hypoxia. The test paradigms used were step-down latency in a passive avoidan...

The anxiolytic, antidepressant and anti-aggression activities of Mentat were investigated in rats and mice, using standard behavioural paradigms. Single acute administration of Mentat, up to a dose of 200 mg/kg, ip, induced insignificant behavioural effects on the test parameters. However, when Mentat was administered subchronically for 7 days at two dose levels (50 and 100 mg/kg, intragastrica...
