Homeopathy is a therapeutic system of symptom similarity based on the axiom of “Like Cures Like” (Nature’s Law of Cure). Homeopathy has gained a substantial popularity across the globe, owing to its clinical efficacy, affordability, easier applicability, and no reported side effects. Homeopathy is the second largest practiced complementary and alternative system of medicine worldwide (World Health Organization). Currently it is practiced in over eighty countries, is legally recognized in forty-two countries and is a part of the healthcare system in twenty-eight countries.

Since inception, Homeopathy is compared with the conventional (modern) system of medicine especially in terms of modern pharmacology which “knows” physical and chemical interactions between drugs and living cells.In conventional medicine too, it was difficult to define the exact ‘paths’ from medicine to biology, then to chemistry and physics, for decades, but research in this area took an edge over it. On the other hand, homeopathy has been neglected especially from research point of view. Fueled research, scientific interactions, and standardization work is needed in every system of medicine to keep it ahead, understandable, and acceptable.

The controversy and priority issues have always ignited intellectual minds to explore “whether homeopathy works, and if yes, how does it work?” A lot of research has been carried out till date to establish the presence, and action of UHDs from various aspects of homeopathy, agronomy, veterinary or dentistry etc. But despite such advances, research in homeopathy is still a challenge, attributed to a limited number of research studies (especially in comparison to conventional research), complex nature of UHDs, inadequate exposure, limited resources, inaccessibility to published literature, poor motivation, lack of experience, skepticism etc.

Research is a constant need to explore, establish, answer and support homeopathy!
