The document discusses the importance of thoroughly documenting a patient's full set of symptoms in order to determine the most appropriate homeopathic treatment. It notes that no single patient exhibits all the symptoms of a disease, so physicians must examine multiple patients to develop a complete picture. This is especially important for chronic diseases like psora, where individual patients only show a portion of overall symptoms. Once a full symptom profile is established, physicians can select a similar medicinal substance from known remedies to target the whole disease state.
