Question
Is syphilis caused by nervous system interference? Is that what you where taught or do you believe this. If so, what is your evidence. I don't want to come across as combative, I just want to ensure dogmatic beliefs are kept to ones self and science is being answered ethically and evidence based.

Again, don't take this personally, everyone has a right to practice what they believe as long as they are licensed, I just want to know how you arrived at that conclusion.

Sincerely with respect,
T.D.

Answer
Syphilis, Gonorrhea, Herpes, whatever you want to call it, are all the bodies physical expression of a medulla insult.  The medulla insult directly causes abnormal function and a lowered internal resistance.  When one suffers from a lowered internal resistance, they are more susceptible to external forces overcoming and showing up as a disease or sickness.  
By assuring that you are functioning without pressure on the brainstem, with a normal mental quantity flow, you raise your internal resistance or immune response to be able to combat these foreign invaders from overtaking your body.  Did I just say that this was the cure for these STD's?  No, I did not.  Did I just say that if your nervous system was functioning normally that you would not get these STD's?  Not necessarily, but you will have the greatest chance to defeat them or not even allow them to exist in your body if your nervous system was functioning properly, with pressure on the brainstem corrected, and normal function restored.
You must have an accurate means of detecting nervous system interference and also a way to prove that it indeed has been corrected.  This is very different from your basic chiropractic premise of treating pain and some symptoms.  This is correcting the underlying cause and allowing the innate wisdom of the body to do it's job.  When that is allowed to happen, people do quite well, I am proud to say that I witness it nearly every day in my clinic.  I do not take any credit for the amazing power that is the greatest doctor within each and every person.  Thanks for asking.
