Wikipedia, in a long and informative article about Osteopathy, states that: "(Osteopathy) emphasises the interrelationship between structure and function and recognizes the body's ability to heal itself; it is the role of the osteopathic practitioner to facilitate that process".
The principles about health and disease on which Osteopathy was developed and continues to flourish can be summarised as follows:
The job of the Osteopath is therefore to find the impediments to the self-regulatory, self-healing processes and help to alleviate them as much as possible, within the limits of what the body is capable of at any one time.
Any tissue or organ of the body, whether bone, skin, or muscle, depends for its health, and indeed its very existence, on having a good blood supply; good drainage; and an uninterrupted nerve supply. It is these considerations that will shape the osteopath's thinking to determine suitable treatment, while always being aware of the first principle of wholeness and unity.
But wholeness comes from aspects of the person beyond the purely physical. We need to understand a person's history, and something about their way of life, to be able to advise them about the most suitable regime of treatment and maintenance.
