ABSTRACT

<p><b>OBJECTIVE</b>To do some comparative study on anti-inflammatory and antipyretic effects between the Dao-di herb and non Dao-di herb of Huangqin (the roots of Scutellaria baicalensis) and provide thinking and evidence for study on geoherbalism and clinical usage of Huangqin.</p><p><b>METHOD</b>The anti-inflammatory action was assessed by auricular swelling induced by dimethylbenzene in mice and the antipyretic action was monitored by dried yeast-induced mice fever.</p><p><b>RESULT</b>All samples of both Dao-di and non Dao-di herbs of Huangqin showed antipyretic effect. The Dao-di Huangqin samples showed antipyretic effect between 61% to 53% , whereas the non Dao-di Huangqin samples between 53% to 43%. Six Dao-di Huangqin samples showed better antipyretic effect than four non Dao-di Huangqin samples. All samples of both Dao-di and non Dao-di Huangqin showed anti-inflammatory effect. Dao-di Huangqin showed anti-inflammatory effect between 73% to 54%, whereas non dao-di Huangqin between 53% to 34%. Six Dao-di Huangqin showed better anti-inflammatory effect than four non Dao-di Huangqin. In totality, results from analysis of geoherbalism showed that geoherbal production areas of Huangqin had better effect than that of the non geoherbal production areas in anti-inflammatory and antipyretic effects.</p><p><b>CONCLUSION</b>Both the Dao-di and non Dao-di Huangqin have effects of anti-inflammatory and antipyretic to a certain extent, but the efficacy of the Dao-di Huangqin surpass the non Dao-di Huangqin.</p>
