This is not a book on how to utilize medications, diagnose disease, or treat patients. Codex Alternus is a book with a plethora of non-drug treatments for schizophrenia, bipolar disorder, and medication-induced side effects. The book covers therapies that include natural antipsychotics, herbs, vitamins, minerals, essential fatty acids, antioxidants, mind-body therapies, prayer and spiritual healing, biofeedback, transcranial stimulation, light therapy, and many, many, more. Many therapies in Codex Alternus have been used in the field of mental health for decades and many other evidence-based therapies have been buried in psychiatric literature on medical databases and not been exposed to the mainstream public before. The book has nearly 900 scholarly citations and summaries--covers over 500 different complementary and alternative therapies which are cited in medical literature--many which are from peer-reviewed journals. The book is designed to spark ideas and be used as a reference tool for clinicians and researchers. It is also an ideal book for those in mental health product development. The book can also be used by care givers and psychiatric patients when proper research is conducted before choosing therapies and utilizing them. The book highlights the conclusions to these scientific medical articles and allows the reader insight into new and traditional therapies, novel, and experimental therapies, and older early 20th century treatments. The reader will truly be amazed at how many evidence-based choices they have for clinical use and product development. Codex Alternus is an easy-to-reference book, with complete citations: PubMed identification numbers, digital object identifier numbers, and publisher names. This book will help many clinicians, researchers, and inventors, as well as care givers and patients.
