ETHNOPHARMACOLOGICAL RELEVANCE
The roots of Rubia tibetica are chewed as an antidote to anaphylaxis caused by bites of the tick Ornithodoros lahorensis by the Wakhi people in Afghanistan.
AIMS OF THE STUDY
To test whether Rubia tibetica possess anti-histamine effect.
MATERIALS AND METHODS
Water and ethanol extracts of roots of Rubia tibetica were tested for anti-histamine effect on the H1-receptor in the guinea pig ileum assay. Fixed concentrations of plant extract with increasing concentrations of histamine were examined. Mepyramine was used as control.
RESULTS AND CONCLUSION
The ethanol extract of Rubia tibetica showed dose-dependent anti-histamine effect, whereas the water extract had little activity. The chewing of Rubia tibetica roots may alleviate the fatal swelling of the tongue during anaphylaxis.
民族药理学相关性
阿富汗瓦克人咀嚼西藏茜草根作为抗蜱 Ornithodoros lahorensis 叮咬引起过敏反应的解毒剂。
研究目的
测试西藏茜草是否具有抗组胺作用。
材料和方法
用水和乙醇提取西藏茜草根，在豚鼠回肠试验中测试其对 H1 受体的抗组胺作用。用固定浓度的植物提取物与逐渐增加浓度的组胺进行检查。甲哌啶作为对照。
结果与结论
西藏茜草的乙醇提取物显示出剂量依赖性的抗组胺作用，而水提取物活性较小。咀嚼西藏茜草根可能会减轻过敏反应时舌部致命肿胀的程度。
