Chiropractic doesn't treat the common cold. However, patients of mine have noticed that their natural resistance to colds increases and chiropractors have often heard patients tell them that, "I haven't had a cold (or if I get a cold I get over it so much faster) since I've been under your care." Natural resistance is the only reason why your cold "goes away" rather than lasting weeks, months, or your entire lifetime!
Chiropractic care can help raise your natural resistance to disease by removing a serious interference to your proper body function: vertebral subluxations.
