Great information to share!A good time to share this post again... “There is no scientific evidence that homeopathy works”
This is probably the most frequently quoted, completely inaccurate statement about homeopathy. Homeopathy research is a relatively new field, so it’s true to say that there are not a huge number of studies, but some evidence is very different from no evidence.
By the end of 2014, 189 randomised controlled trials of homeopathy on 100 different medical conditions had been published in peer-reviewed journals. Of these, 104 papers were placebo-controlled and were eligible for detailed review:
41% were positive (43 trials) – finding that homeopathy was effective 5% were negative (5 trials) – finding that homeopathy was ineffective 54% were inconclusive (56 trials)
How does this compare with evidence for conventional medicine?
An analysis of 1016 systematic reviews of RCTs of conventional medicine had strikingly similar findings:
44% were positive – the treatments were likely to be beneficial 7% were negative – the treatments were likely to be harmful 49% were inconclusive – the evidence did not support either benefit or harm.
Although the percentages of positive, negative and inconclusive results are similar in homeopathy and conventional medicine, it is important to recognise a vast difference in the quantity of research carried out; chart A represents 189 individual trials on homeopathy, whereas chart B represents 1016 reviews on conventional medicine, each analysing multiple trials.
This highlights the need for more research in homeopathy, particularly large-scale high quality repetitions of the most promising positive studies.
The difference in quantity is also not surprising when one considers the tiny amounts of funding made available for research into ‘complementary and alternative medicine’ (CAM). For example, in the UK only 0.0085% of the total medical research budget is spent on CAM, of which homeopathy is only one example.
