Open minded, but when you're talking about patients in many cases anything that can make them feel better is fine. The real danger is when these practitioners do not screen for real disease states and instead act in their own monetary interests.
The best alternative medicine there is, is simply to smile, eat well, have a positive outlook and try not to be so sedentary.

If someone is seeking alternative medicine, they should seek conventional medicine first. Most disease can be treated and cured with no long term ill effects if it's caught early enough. So learn to listen to your body.
