Neurosedative and muscle relaxant activities of aqueous extract of Bryophyllum pinnatum.
- PubMed: 15752629
The saline leaf extract of Bryophyllum pinnatum was investigated on neuropharmacological activities to ascertain claims of local use. When tested in mice, it produced a dose-dependent prolongation of onset and duration of pentobarbitone-induced hypnosis, reduction of exploratory activities in the head-dip and evasion tests. Moreover, a dose-dependent muscle in-coordination was observed in the inclined screen, traction and climbing tests. It delayed onset to convulsion in both strychnine- and picrotoxin-induced seizures in addition to minimal protection against picrotoxin seizures.
