Objective: To explore the mechanism of anti-rheumatic effect of the active fraction of Siegesbeckia pubescens (AFSP). Methods: Adjuvant arthritis (AA) model of rat was produced to observe the effect of AFSP on lymphocyte proliferation, interleukin-1 and -2 (IL-1,-2) activity, pathologic section of ankle joint, and analgesic effect, in model rat. Results: AFSP could reduce the inflammatory pathologic response of ankle joint. It has good analgesic effect, the analgesic rate being 65%. AFSP could also strengthen T-lymphocyte proliferation, promote IL-2 activity and inhibit IL-1 activity. Compared with the control group, the difference was significant (P<0.01). Conclusion: By means of regulating the immune function of organism, AFSP could improve the local pathologic response to antagonize against rheumatism, therefore, it is an effective anti-rheumatism herbal medicine.
