This work is a continuation of Dr. Grigorova's previous book Electro Acupuncture by Voll (EAV) and Homeopathy (2012), Milkana publishing, Santa Clara, CA, USA, which examines in detail the method of Dr. Reinhold Voll and how to use it to test for allergies and pathogens in humans and provides valuable tables with the best homeopathic remedies for curing of these allergies and pathogens. This new book is a practical application of Dr. Reinhold Voll's achievements in diagnostics and treatments based on balancing the energy state of human body organs. The book presents many clinical cases based on patients Dr. Grigorova has tested by the Voll method and successfully treated with classical homeopathic remedies, vibrationally prepared medications and herbal formulas selected by the Voll test. Of the total 239 clinical cases reported, there were 84 treatments for viral etiology, 76 cases of bacterial pathogens, 19 cases covering fungal infections, and 60 clinical cases describing parasitic infections. They demonstrated the following: 1. Diagnosis can be achieved in a radical new way, without human blood and secretion samples and without invasive tests and painful manipulations, by physically detecting the organism's and present pathogens' vibrational states. 2. Effective and gentle treatment based on the energy principle can be applied for any known microscopic or larger pathogenic organism. 3. It is possible to test and find treatment medication, resonant with a pathogen's vibrational frequency characteristics even when the pathogen is unknown or unclassified. The English language edition is divided into two volumes. The first presents the theory of the Voll method and 84 clinical cases with viral etiology including Human Papilloma, Hepatitis, Cytomegalovirus, Coxsackie, Epstein-Bar and other viral infections like Poliomyelitis, Rabies, Molluscum Contagiosum, Adenoviruses, Rotaviruses, Herpes and SARS-COV-2. The second volume covers bacterial, fungal and parasitic infections. The theoretical part shows that the Voll method is based on the contemporary knowledge of quantum physics applied on the interactions between the cells, the organs and the systems of the human body. At the heart of all reasoning in this book lies the philosophy and ideas of modern quantum physics-everything in our known world is vibration, energy and information. The physical objects, as well as the human body, exchange energy and information with the environment through vibrations. Any energy and information disorders can be efficiently corrected on a vibrational principal, with medications delivering frequencies resonant with the body according to its particular energy needs at the moment. The viral infections and their treatment are a very important problem, which has become evident with the latest viral illness invasion, COVID-19. The problem is the same for other viral infections known today: There are not enough antiviral medications. The Voll method, on the other hand, offers diagnostics of the type of the viruses (using testers) and an opportunity to find specific medicine and the best vitamins and supplements for each patient with viral infection. It can really be a potent tool in fighting infections such as COVID-19.
