  1. A total of 152 participants will be randomized into the control group or the experimental group. Assessors blinded to the randomization will collect data during the intervention period at baseline and at study months 1, 2, and 3. The peripheral blood levels of matrix metalloproteinase 3 (MMP3), matrix metalloprotease 1 (TIMP1), and soluble cluster of differentiation 14 (sCD14) will be detected before and after treatment to explore the biochemical mechanisms of Guizhi-Shaoyao-Zhimu decoction for the treatment of active RA
