Most of the modern chronic diseases are not contagious diseases. They are not caused by bacteria or viruses. Based on my clinical experience with holistic herbal medicine, I strongly believe that the root causes of most of the modern chronic diseases are in nutritionally imbalanced diet, unhealthy lifestyle factors, lack of physical and breathing exercises, mental stress, and stressful physical and social environments in which one is living, working, and travelling. Correction of these factors and customized herbal medications can cure most of the modern chronic diseases including coronary artery disease. If they cannot be completely cured in case of some diseases, they can be managed to be within acceptable limits to permit normal life with pure herbal medications and without any side effects.
