“This is the eighth volume in the publisher's ongoing "Principles of Health" series. The volume adopts an ambitious scope, covering six general areas: the immune system, genetics, allergies, immune system diseases, general diseases, and medications. Organized under these categories are 119 concise summary articles covering the basic science concepts underlying allergies and immune disorders and providing clinical overviews for select allergies, immune and autoimmune diseases, applicable prescription drugs, and natural products. Each signed clinical entry provides key terms and definitions, a diagnostic profile, likely treatments, and references… The volume self-identifies as "easy-to-understand" and is geared for researchers and students in health care fields. The various contributing authors do well in presenting complex medical information at an accessible level appropriate for a lay audience… The book under review is most appropriate for undergraduate students and general audiences. Summing Up: Recommended. Lower- and upper-division undergraduates. Students in two-year technical programs. General readers.” -CHOICE
