> Sometimes this leads to a situations that non-fully proven alternative treatments can offer better results with less side effects than current medicine practice. And since risk for many alternative medicines is low it makes sense to try them.
This is a strange sentence. So this hypothetical alternative treatment has been shown to work better and with less side effects and also that it's risk is low, but is only "non-fully proven".
If you showed low risk and better efficacy and less side effects then that's pretty much fully proven. What's left?
