Epstein-barr is also known as mono. He likely is using homeopathic remedies that are acidic because acids destroy things like viruses, microbes, yeast, etc. Examples include folic acid, citric acid, tartaric acid. Different acids destroy different bugs. Citric acid for instance is good for fighting microbes. He also is a doctor that believes that acidic pH allows for the body to break down and for disease to take hold (which is what my doctor believes). In my opinion you likely found one of the few good doctors in your area.
