The Scientific Homeopathy - Theory and Practice of Homeopathic Healing by Georgos Vithoulkas is a foundational work of classical homeopathy. It provides both aspiring and experienced homeopaths with an invaluable and timeless treasure of knowledge about classical homeopathy and the function of the human organism. Georgos Vithoulkas' "Scientific Homeopathy" consists of two volumes: "Theory and Practice of Homeopathic Healing" and "The Levels of Health." Both volumes are essential for Vithoulkas' students. Alongside "Materia Medica Viva," they are among his most important works and are considered the essence of his contributions. The book outlines, among other things, fundamental laws and principles of healing, a definition of health from a homeopathic perspective, as well as theoretical and practical foundations necessary for practicing homeopathy.
