Abstract
To elucidate the effects of Onkyungtang. after oral administration of Onkyungtang water extract in mice and rats, acute toxicity. analgesic. sedative, estrogenic actions. action on isolated uterine muscle were measured. The results obtained were as follows: 1. The yield of water extract of Onkyungtang was 24.5%, minimum lethal dose was 4,000mg/kg, which rarely had the acute toxicity in mice and rats. 2. The analgesic effects of Onkyungtang by acetic acid induced writhing syndrome in mice were not remarkably observed. 3. The relaxant action of Onkyungtang on oxytocin induced contracted uterine muscle in estrogenized rats were not remarkably observed. 4. The sedative effects of Onkyungtang by hexobarbital sodium induced sleeping time in mice were remarked. 5. Administration of Onkyungtang caused remarkable increase in weight of rat's uterus.
