ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the influence of borneol on nasal absorption enhancement of ligustrazine.</p><p><b>METHOD</b>The rats were randomly divided into 3 groups: Xiongbing nasal spray group (group A), Chuanxiong nasal spray group (group B) and Xiongbing group by decoction intragastric administration (group C). All the rats were decapitated at several time points after administration. The whole brains of rats were taken to homogenate and detected the concentrations of ligustrazine.</p><p><b>RESULT</b>Compared with group B and C, group A has its characteristics: quick absorption, quick distribution and quick excretion of ligustrazine.</p><p><b>CONCLUSION</b>Nasal administration is a quick-acting way for ischemic cerebral vessel insufficientia. Borneol promoted nasal absorption of ligustrazine into brain.</p>
