The origins of naturopathy can be traced back thousands of years to ancient Shamanic, Indian and Chinese civilisations where the use of herbs and cleansing methods helped to treat disease and improve health. Around 400BC, the teachings of Greek physician Hippocrates were rooted in the idea that nature is the healer of all disease.

Naturopathy , principles and philosophies ,originated in Germany and Europe around 18 th Century . But the ancient traces of philosophical roots of naturopathy are linked to India ,Greece and many more . In Indian history, the naturopathy evidence is found in the Swastha Vritta which means ' Naturopathy' . In Europe , the original naturopaths – prior to 1900s – from around the world, were trained by European doctors using hydrotherapy, herbal medicine and other traditional forms of healing. Naturopathy term was first term coined in 1885 by Dr. John Scheel, a German homeopath practicing the methods of European Hydrotherapy . Dr. Benedict Lust was the founder of naturopathy in North America . In 1902, he founded the American School of Naturopathy. The years from 1900 to 1917 were formative ones for naturopathic medicine in America as the various forms of natural medicines were combined into one eclectic system. Here the American dietetic, hygienic, physical culture, hydrotherapy, spinal manipulation, mental and emotion healing, Thompsonian/eclectic (botanical/herbal medicine), and homeopathic systems of natural healing were all merged into naturopathy.

During the ancient era , the holistic system of medicine is used to treat patient by suing natural medicine but would also educate them about a healthy lifestyle.
According to Naturopathy, "A disease can be treated by regulating diet without taking any medicine"
The naturopathic principles taught in most countries include:
First, Do No Harm (primum non nocere)
Healing Power of Nature (vis medicatrixnaturae)
Treat the Cause (tollecausam)
