This book gave me hope for the first time of overcoming all my allergies for good. The author describes her view of the key role of digestive problems in causing allergies in the first place, and describes the path to overcoming the digestive problems and eliminating the resultant allergies. The health benefits the author describes are not just relieving of asthma symptoms, but include curing infertility, chronic infections, high blood pressure, and many, many other health problems. I cannot recommend the book highly enough for anyone with any allergies, past or present, who is having health problems which trouble them. This book's importance is not to be underestimated.
