Query: thyroid balance review

If you are looking for a book that outlines traditional and alternative methods for treating thyroid disorders, this is NOT the one to buy. In fact, it covers this topic in the last quarter of the book and only in a couple of pages. Mostly covers the endocrine system, symptoms, signs, thyroid drugs, differences between hypo and hyperthyroidism. This information is ok for those who are newly diagnosed and need more information. Does not provide any insightful methods on alternative methods for treatment.
