All medical therapies are enlightened by the struggles between mankind and nature. Natural therapy，which is the agglutination of disease treatment experience of human ancestors，is the most primitive medical method. Currently，natural therapies in China mainly include nutrition therapy，homeopathic therapy，physical therapy，aromatherapy，hydrotherapy and psychotherapy，all of which treat diseases with natural substances. The seven philosophical views on natural health are as follows：having no toxic or side effects；exerting the self-healing ability of human body；identifying real disease causes；following the concept of holistic medicine；emphasizing prevention over treatment；doctors are also teachers；achieving both physical and mental health. The five causes of diseases include cell intoxication，cell hypoxia，uneven cell nutrition，cell water shortage and poor microcirculation. Natural therapy，which has a long history，is faced with many problems at present，including weak theoretical researches，shortage of policies，systems and models，inconsistent connotations and categories，lack of supervision，access and efficiency evaluation systems as well as talent training mechanisms，low barriers to entry and insufficient awareness of natural therapy.
