I am from India and I also am a regular user of homeopathy. In case it was all placebo and fools your brain in thinking that you are actually taking some real stuff in and not just sugar and water and you see the effect physically on your body then you would have found mention of this in Ayurveda and Yoga since both stress on meditation which is a way to control your own energy and mind state and by doing meditation you would have been able to cure your body of every disease.

And allopathy is a major money earner for a lot of corporations and they go to every effort to tell the people that any other medicine system be it unani, ayurveda, acupuncture, acupressure, homeopathy, etc are false and bad.

In case you have not tried homeopathy then give it a go for small illness like fever, diarrhea, body pains, etc and test it for yourself. Also go to a doctor who is recommended by someone. Doctor's knowledge is the most important part in homeopathy as it is in all other non-allopathic systems.
