It is often the case that an alternative therapy's roots are steeped in history as can be seen with acupuncture, which is a practice over 2500 years old. It however, does not have to be the case since some alternative therapies are based on more modern ideas such as osteopathy, which was founded in the late 1800's. Although still thought of as 'alternative' a lot of these methods of healing have made their way into the mainstream and are used by conventional practitioners.
