Scientists now agree that most pathological conditions are due to a lack of oxygen at the cellular level. Air pollution, depleted foods, and poor breathing habits can lead to chronic oxygen deficiency, creating an environment in the body where toxins thrive while the overall immune response weakens. Through oxidative therapies—the medical use of ozone (O3) or hydrogen peroxide (H2O2)—we can help the body produce the oxygen needed to oxidize viruses and bacteria as well as weak and sick cells, so that stronger and healthier cells can take their place. The author also explores the extended use of oxidative therapies in veterinary and dental medicine, including their success in treating cavities and preventing infections. Providing a detailed resource section, he explains how to combine oxidative therapies with holistic methods, such as fasting, detox regimens, herbal medicine, and nutritional therapy, for a stronger start on the path to optimum health.
