摘要

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.
