Evidence that homeopathy doesn't work? Pretty simple, every single experiment under controlled conditions that was started in an attempt to show that it does work.
When something is indistinguishable from a placebo the only conclusion can be that it is exactly as effective as the placebo. Since the placebo is known not to provide a benefit, the conclusion is that homeopathy provides no benefit.
If I were to rely on personal testimony I would have to accept all kinds of things that have never happened. Further, if I have to provide evidence that things don't happen despite a complete lack of evidence that they do the default position on all postulates would be acceptance.
This flies straight in the face of reason, science, and any other empirical process for establishing the truth value of a given claim.
The null hypothesis for any postulate is negative. For an existence postulate (god) the null hypothesis is lack of existence. For a postulate such as the effectiveness of homeopathy the null hypothesis is that it doesn't work.
You cannot hope to make headway in this discussion until you recognise that science, and the scientific method, are nothing more than a means of establishing the validity of hypothesis. The default position is always the negative, the lack of effect.
