Answer:
Homeopathy is non-toxic system of medical science originated in Germany by Dr. Friedrich Samuel Hahnemann (1755-1843) (the founder and father of homeopathy). He was M.D. in conventional medicine. He realised his own school of medicine (conventional) was not helping the patients and spent years researching on homeopathy. The term "homoeopathy" was coined in 1807.
Homeopathy is the treatment of disease by substance that cause similar symptoms (Like treats like), but in such high dilutions that little or no substance actually remains left. In other words, treatment is with water. There is no scientific basis for homeopathy, and it is thought to work largely by placebo effect.
