It really is that simple:

Chiropractic is based on four ideas:

1. The body is a self-healing mechanism.  If you cut your finger, it heals.  If you cut the finger of a corpse, it does not heal.  The difference is life - it is life that heals.
2. The nervous system is the master system of the body - EVERY aspect of the human experience is processed through the nervous system.
3. When there is interference with the function of the nervous system, not only can that compromise your physical well-being, but because it distorts your perception of the world and compromises your ability to respond to the world, it can have psycho-emotional consequences too.  
4. What I do as a Doctor of Chiropractic is analyze, locate, and correct the cause of that interference.  YOUR body does the rest.  Healing from the inside out.
