Naturopathy is based on the principle of using natural methods like water, air, light, heat and diet to treat disease without drugs. It views the body as inherently self-healing and aims to support this through lifestyle practices and eliminating toxins. The document outlines several foundational principles of naturopathy including the unity of disease and cure, the foreign matter theory of disease, and the toxemia theory. It also discusses the five elements - earth, water, fire, air and ether - that make up the human body according to naturopathic philosophy.
