Many natural therapies also take a holistic and non-invasive approach to health and healing. The holistic approach takes account of the physical and emotional aspects of an individual’s health, with a view to preventing negative impacts, such as disease and illness taking hold. the most widely used natural therapy is Traditional Chinese Medicine (TCM), a healing tradition that goes back many centuries and is still in widespread use today. Naturopathic medicine recognizes the body's inherent ability to heal itself. This approaches health and healing from a perspective largely based on the yin and yang concept, which is informed and inspired by nature. This philosophy attempts to maintain harmony and balance in the mind and body, while trying to understand the complex relationships that exist in human biology.
