Holism (from ὅλος holos, a Greek word meaning all, entire, total) is the idea that all the properties of a given system (physical, biological, chemical, social, economic, mental, linguistic, etc.) cannot be determined or explained by its component parts alone. Instead, the system as a whole determines in an important way how the parts behave.Holistic health is a philosophy of medical care that views physical and mental and spiritual aspects of life as closely interconnected and equally important approaches to treatment.The goal is a wellness that encompasses the entire person, rather than just the lack of physical pain or disease. This means that not feeling sick, does not necessarily mean you are well, just that you are between Well and Sick. When symptoms develop, it is often long after the cause of the symptoms occurred. It is often used in contrast to the medical model that focuses on treating symptoms and syndromes without attempting to address functioning beyond the absence of disease, the Holistic approach focuses on the cause.The holistic process offers individuals the opportunity to be the creators of their own reality of health, through an understanding of all levels of health and a balanced lifestyle
