"There’s only a few books a year that I think really deserve to be in everyone’s library. This is one of them. . . . It’s loaded with great information, and it can save your life or the life of someone you love.”—Dr. Joseph Mercola, founder and director, mercola.com

"Heart disease is a national crisis, and the most common treatments don’t lower the risk of death in most cases. Rather than despair, Thomas Cowan meets these devastating realities with the firm belief that there must be another solution. Through many years of research and medical practice, he challenges the common notion of what the heart is for—to pump blood. Through observation, geometry, and scientific insight, he proposes that the heart is a hydraulic ram rather than pump because it uses suction rather than force to build the momentum of the blood. And he makes it clear that this change of perspective makes all the difference by exploring heart attacks, what they aren’t and what they are. The treatment Cowan advises in Human Heart, Cosmic Heart is personal and holistic (whole-body remedies), driven by the patient’s own life story in order to show the whole of the nervous system. The result is a refreshingly balanced approach focused on responding to the needs of the body rather than reacting to the problem experienced in the heart. Throughout the book, Cowan shares his personal journey of learning, making the book approachable and warm as well as logical and authoritative. By sharing his learning process, he conveys a deep understanding of the cardiovascular system and its needs. Cowan, a self-proclaimed doubter and nonconformist, brings a voice of skepticism and hope into a genre packed with dry, black-and-white thinking. His insights are relentlessly rooted in research, and he explains medical science in an accessible way, including clear diagrams and step-by-step explanations that move at just the right pace for educated adults without moving too slowly for medical professionals. This book is life-changing for those trying to understand their own bodies, or those of loved ones, and it’s truly transformative in the hands of medical professionals, especially young doctors.”—Foreword Reviews

“This book blew my mind. I will admit . . . I thought I was simply going to be reading an interesting memoir of a good physician. Instead, I discovered the most groundbreaking, unorthodox, outside-the-box treatise on the heart I have ever stumbled upon. If you have a heart and you want to live a long time, you must, must read this book.”—Ben Greenfield, author of the New York Times bestseller, Beyond Training; founder and owner, Greenfield Fitness Systems; www.bengreenfieldfitness.com

“What happens when the medical profession views the heart as a mechanical pump? We get ghoulish surgeries, medications with horrible side effects, and soulless low-fat diets. Tom Cowan asks us to look anew at the heart; first step is the demonstration that the blood pumps the heart, not vice versa. From this observation comes a way of treating heart disease that is more effective, more gentle, more felicitate than conventional protocol. Part biography, part wisdom, part practical advice, Human Heart, Cosmic Heart will change the way you look at the process of healing and the miraculous world of the human body.”—Sally Fallon Morell, President, The Weston A.
