To observe the effect of Guci Powder on foot swelling induced by egg white in rats. 50 male rats were randomly divided into normal saline group (n=10), white vinegar group (n=10) and Guning lotion group (n=10). There were 10 rats in the high-dose group and 10 in the low-dose group. The rats in each group were treated with the drug on the left and right feet of the rats. 0.5 hours after the last administration, the rats in each group were inflamed. The left hindsole plantar volume was measured respectively, so that the difference of the posterior toe volume before inflammation was taken as the swelling degree, and the swelling degree of each group was calculated. Compared with physiological saline group, the rats’ egg white toe swelling (P<0.01) was significantly inhibited at 0.5∼6h after administration. The swelling of egg white toe in rats was inhibited at 0.5∼2h (P<0.05). Bone spur powder has a good intervention effect on the model of toe swelling induced by egg white in rats, and the external application of bone spur powder has anti-inflammatory and swelling effect.
