Is this system not the so-called alternative system of medicines such as homeopathy, ayuraveda, naturopathy, acupuncture, hypnosis, pranic healing etc.?

No really. Not the way these systems have changed over in modern times. The term "pathy" means some kind of treatment. The approach here is towards improving the health and not targeting towards treatment per say. You many find some principles of ancient ayuraveda, naturopathy, etc. though.  more
