western science is extremely limited, and mainly because of arrogance and superiority complex.
yes we DO heal a lot of stuff on our own, and what things like homeopathy and ayurveda do is exactly to help your body do the healing by itself, with just a gentle help.
You give proper treatment to some people, and you give a placebo to others. Then you check if there's any difference.
I don't see how that would work with western medicine and not with homeopathy and ayurvedic medicine. Please explain.
While I am not an authority on whether such double blind tests have been performed or not, I do know that the Eastern medicine systems have been in use for a few thousand years. There are proper University courses, regular practitioners, and thousands of success stories.
Do look up Ayurveda.
Fooling themselves is perfectly possible with controls and blind tests too..
