It works according to what proof? Do you know of a scientific article that compared homeopathy against a control placebo that showed homeopathy outperforming the placebo?
That is the core problem, ie in how far is personal health is measurable. For example my parents go to a MD who uses quite a lot homepathic approaches. They are going there every other week and he uses in my opinion a mixture between psycho theraphy, wonder waters and if it is serious some real medicine. I think it is a great comnination as it gives them stability and the feeling of having someone really supporting them with their health. If I were older I would do the same - if you go to the doctor only if you have some urgent issue it might be already to late. This ongoing process makes you very aware of changes in your health/body.
