In the late 1920's, Dr. Edward Bach, a renowned British scientist and physician, observed that his patients' healing and well-being were directly influenced by their state of mind and emotional health. He noticed that the personality, attitude and present outlook of a patient had a great deal to do with their being cured or remaining sick. He understood that "the personality of the individual is of even more importance than the body in the treatment of disease". He realized that, instead of treating the patient as a body with an illness, the patient needed to be treated like an individual. "Treat the patient, not the disease."
