Daim ntawv thov: salicylic acid(CAS: 69-72-7)yog ib yam khoom ntuj extract los ntawm Willow bark, paub zoo tias yog ib tug antiinflammatory thiab antinociceptive tus neeg saib xyuas thiab ib tug nyob ze yam ntxwv txheeb ze rau acetylsalicylic acid (aspirin). Salicylic acid yog ib qho chaw cog qoob loo uas muaj ntau yam kev tswj hwm kev koom tes hauv cov kab mob hauv zos thiab cov kab mob kis tau zoo. Cov tshuaj tiv thaiv kab mob thiab tshuaj tiv thaiv kab mob uas tsim los ntawm Salicylic acid thiab nws cov derivatives hauv cov tsiaj yog vim inhibition ntawm COX-1 thiab COX-2 (cyclooxygenase) enzyme kev ua thiab kev tawm tsam ntawm prostaglandin biosynthesis. Salicylic acid kuj yog qhov txaus siab los ua cov khoom pib rau cov organic synthesis ntawm ntau dua COX suppressors thiab lwm cov qauv tshuaj.
