How do you decide which system of medicine is better, if you are not objective?

I don't trust homeopathy myself, but I am a little wary of a bunch of allopaths making the case for homeopathy's inutility as a treatment method. That seems so self - serving. But then where is the middle ground? How does one decide which treatment is better in an objective manner?

That is the same question that homeopathy doctors are asking? And this study comes from the same organization that reported homeopathy drugs are 245% better than placebo. Talk about self - contradictory!
