These results and existing experiments indicated that active ingredients in SCL, including isorhamnetin (18), polydatin (4), oxyresveratrol (30), and piceatannol (21), could inhibit the activity of PTGS2 to decrease the synthesis of PGE2 [71], which contributes to the restoration of PID by inflammatory inhibition. The gene discussed is PTGS2; the disease is pelvic inflammatory disease.
