IS THE 'NATURAL REMEDIES' INDUSTRY UNFAIRLY DIAGNOSED BY WESTERN MEDICINE PROFESSIONALS?

HERE IS MY QUESTION. WESTERN MEDICINE REQUIRES DOUBLE-BLIND CONTROLLED STUDIES. THEY SAY, "THE ONLY THING NATURAL REMEDIES INDUSTRY HAS ARE ANECDOTAL TESTIMONIES." BUT WAIT !! WESTERN MEDICINE HAS ANECDOTAL TESTIMONIES, TOO!! WHY ARE THEY SOMEHOW VALID FOR WESTERN BUT NOT VALID FOR NATURAL REMEDIES? WHY DO "ALLOPATHS" ACCEPT ANECDOTAL INCIDENTS TO PROVE WESTERN MEDICINE, BUT DON'T ALLOW ANECDOTAL INCIDENTS AS VALID FOR NATURAL REMEDY INDUSTRY?? THANK YOU FOR YOUR REPSPONSES.
