The effects of Hypericum perforatum (St John's wort) on morphine withdrawal syndrome and comparison with clonidine have been investigated in morphine-dependent rats. Adult male Wistar rats were subjects. The frequencies of withdrawal behavioral signs (rearing, teeth chattering and jumping) induced by naloxone challenge were demonstrated in morphine dependent rats receiving Hypericum perforatum ...

The overall purpose of this study was to investigate Neurostan Saint John’s Wort (SJW) on the disposition of fexofinadine in the isolated perfused rat liver. SpragueDawley (SD) rats (n = 16) randomized into 3 groups, including: control, low dose (Hypericum, one type of neutostan) and high dose group. Each animal among these groups was pre-treated with either vehicle (ethanol in Milli Q water at...
