According to Dr. Joseph Pizzorno, seven core healing systems maintain our bodies' strength and vitality, with all illness being directly due to weaknesses in one or more of these systems. Recognizing the importance of these systems makes it easier to promote overall good health, improve underlying systemic imbalances, and prevent disease recurrence. Understanding what these systems are and how they work can also empower you to take practical responsibility for your own health through adoption of proper diet, nutritional supplementation, and a healthy lifestyle.
