The book can be read in English but very good. What I find particularly great is the detailed description of possible causes. Also very well explained is the fact that such and related autoimmune diseases. In short, it is spoken not only about Hashimoto or the thyroid but the entire Man considered. A great link between conventional medicine and alternative medicine. The author is a pharmacist and incidentally affected themselves. Who, for example, suffers from Crohn's disease or diabetes, will also find in this book. Very comprehensive written and knowledgeable. The first issue is probably appeared self-published and has small flaws - I personally find to be negligible.
