Objective To study the mechanism of anti-inflammation and bacteriostasis effect of Qinlian Liyan Heji. Methods To assess the anti-inflammatory effect, blood capillary permeability in mice was increased by acetic acid, the swelling of toe in rats was induced by albumen, and granuloma was induced by cotton ball in mice.The agar dilution method was used to check the minimal inhibitory concentration of Qinlian Liyan Heji on Staphylococcus aureus, Staphylococcus epidermidis, Moraxella catarrhalis, Klebsiella pneumoniae.The microdilution method was used to detect the minimal inhibitory concentration of Qinlian Liyan Heji on group A streptococci, Streptococcal pneumonia and Haemophilus influenzae. Results Contrast to the negative control group, Qinlian Liyan Heji significantly inhibited the increase of blood capillary permeability caused by acetic acid in the middle dose and the high dose groups.In the low dose and middle dose groups, Qinlian Liyan Heji obviously reduced the swelling of plantar in 2, 3, 4, 5 h.In the high dose group, Qinlian Liyan Heji markedly lowered the swelling of plantar in 1, 2, 3, 4, 5 h. Qinlian Liyan Heji significantly reduced the granuloma caused by cotton ball. On the other hand, Qinlian Liyan Heji exerted bacteriostatic effect on the above 7 types of bacteria. Conclusion Qinlian Liyan Heji has effects of anti-inflammation and bacteriostasis.
