Here is a very intresting video regarding how chiropractic can help lower your blood pressure.
While I feel this is a good report overall, I would disagree with one key point: I feel that the vast majority of chiropractors (including myself) analayze and correct the alignment of the atlas bone (C1), not "only a small number of chiropractors" as the video says. There are numerous research studies currently being conducted to further investigate this. This has far-reaching consequences, as roughly half of all American adults have high blood pressure. I've had numerous patients who, after beginning their chiropractic adjustments, I have had to refer back to their MD for reduction of blood pressure medications.
