You know, in researching about Crohn's and the protocol, I came across Probiotic treatment, along with others. I noticed that there is a link with Autism and OCD treatments there, as well. The probiotics started helping my son with his acne, as well. Only in running out of the probiotics and having to reorder them, did he notice they really did seem to make a difference for his regularity/pain/inflammation. I put my daughter on it as well, and the acne is already better only three days later!
It's so strange how all these things are interrelated (neuro & physical). Just thought I'd share this observation.
