Answer
The best way to judge the validity of medicine practices is to try them yourself. Try both the complementary and alternative medicine practices and see which one of them works best, and has the best results. It's important to keep in mind that not all that is said on a medicine commercial is true, which is why you often have to test things to see for yourself. It is also helpful to consult your doctor.
NOTE: This method should not be used when the practices are dangerous.
