Naturopathy is way of life and treatment. The five great elements of Nature Viz Air, Sun, Earth, Water and ether are used scientifically for curing the diseases.
Naturopathy is an art and science of healthy living and a drugless system of healing based on well founded philosophy. It has its own concept of health and disease and also principle of treatment. 
Naturopathy is a very old science. We can find a number of references in our Vedas and other ancient texts. The morbid matter theory, concept of vital force and other concepts upon which Naturopathy is based are already available in old texts. The revival of Naturopathy started in India by translation of Germany’s Louis Kuhne’s book “New Science of Healing”. Shri D. Venkat Chelapati Sharma translated this book in Telgu language in 1894. Shri Shroti Kishan Swaroop of Bijnor translated this book into Hindi and Urdu languages in 1904. All this gave a wide propagation to this system.
Here, it may also be mentioned that modern Naturopathy movement was started in Germany and other western countries with Water Cure (Hydrotherapy) therapy. Water Cure was synonymous with Nature Cure in those early days. The credit of making Water Cure world famous goes to Vincent Priessnitz (1799-1851), who was a farmer. Later on, other personalities also made their contribution in this work. The name of Louis Kuhne needs special mention, who propounded the Principle of Unity of Disease and Treatment and provided a theoretical base to this method. The book New Science of Healing written by him has been translated into several languages of the world.
