He says some interesting things, many of which I agree with.
Boy, he sure is quick to start giving hormones! He sounds to me like he thinks many things can be repaired in the body with a little help--*except* the endocrine system...
As for the microdosing cortisol, I'm actually starting to work with the Helen Foundation http://www.microdose.com/
, who uses a combination of food allergy testing and tapered microdoses of cortisol to get people out of the inflammatory cycles that they are in. It makes sense to me, and it works with the lack of patience most people have towards "fixing" themselves (as in, not being able to be off nightshades for several months to truly see the benefit). Even with the microdoses of cortisol, the DIET is the most important thing--after the initial "shower" of cortisol, the patient is weaned off and the diet is the major player. That's why I liked it. I felt like it addressed the cause WITH a little help.
Hearsay from someone else who dealt with several of Dr. Serrano's ex-patients: his initial treatment is great, his follow-up and accessibility to patients not-so-great.
