Unfortunately much of the practice of so-called "healing" today does not have much to do
with healing at all. It is mostly emergency first aid such as setting broken bones, stitching
up cuts, removing tumors, etc. There is also the taking of drugs to kill germs, numb pain
or change the body's chemistry in one way or another.  In most cases this is not true
healing; it is dealing with symptoms.

It is not addressing the cause of the problem.
Does removing the tumor change the body that produced it in the first place?
Does taking antibiotics raise the resistance or immune system of the person who is sick?
Does taking blood pressure medicine change the malfunction that led to high blood
pressure?
How many people every day are taken to the hospital, get worse or even die because of
a bad reaction to a drug they have taken?

In answering your question - The chiropractors' job is to reduce the interference that is
caused by the subluxation. This is done by adjusting the spine to return normal function
to the nervous system. You cannot be truly healthy, reach your full potential or achieve
your greatest healing ability if you have pressure on your nervous system.
There are of course a number of other factors that influence your healing ability:
Diet
Exercise
Stress
Age, etc.

However, if you have a condition or symptom that has not responded to traditional or
other forms of treatment, remember

You haven't "tried everything to get better"
until you have tried chiropractic.
