According to The World Health Organisation, homeopathy is the second largest medical system in the world, with 300,000 doctors treating 200 million patients annually.
People who are anti homeopathy claim that there is no scientific evidence that homeopathy works, but of the 189 randomised control trials up to 2014, 41% were positive, finding that homeopathy was effective. The figures for conventional medicine are just about the same, at 44%. There is no difference.
There is good statistical evidence that both homeopathy and conventional medicine work.
