Claims of homeopathy's efficacy beyond the placebo effect are unsupported by the collective weight of scientific and clinical evidence.[8][9][10][11][12] While some studies have positive results, systematic reviews of all the published trials fail to conclusively demonstrate efficacy.[13][14][15][16][17]
