Do Jews Believe in Alternative Medicine?

There are many medical treatments that are not part of conventional medicine. Many of these unconventional treatments are very popular. What does Judaism say about alternative medical treatments? Are we allowed or perhaps even encouraged to seek alternative medical treatments? May we use them instead of conventional medicine? May we use them to complement conventional medicine? 

Generally, we can violate most laws of the Torah to save a life. Could alternative medical treatment also be used in violation of Torah laws to save a life?

A fascinating discussion about the Jewish approach to alternative medicine.
