Excellent assertation on the possible link to the CNS. I have also considered this theory for quite some time now. However, I am not very familiar with any natural elements to repair certain abnormalities in the CNS as of yet. This still doesn't account for all the others who can attest to SD being related to some form of internal problem in rleation to their symptoms. The CNS is most definately a key element of the master control center and its involvement is most likely implicated. Please don't forget that the adrenal glands are responsible for regulating stress responses. If these were to malfunction, stressful events ie. jobs, love, money would exascerbate the disorder. Got any ideas on how to better manage the CNS?
I know homeopathy does engage the CNS in its treatment of the hypothalamus pituitary and adrenal axis. Check out DR. Shah's online program for Seborheic dermatitis. I tried it years ago. Just didn't sustain the patience to continue beyond 4 months.
