📱 eBook en inglés MEDICAL HISTORY: HOW MEDICINE EVOLVED

disease mechanisms and evidence-based treatment. This history examines how practitioners developed anatomical knowledge, identified pathogens, created surgical techniques, and discovered pharmaceuticals through observation, experimentation, and institutional development that revolutionized human health.
Drawing on medical texts, hospital records, anatomical illustrations, and clinical case studies, the narrative traces medicines evolution through distinct phases. Ancient civilizations developed pharmacopeias from botanical knowledge while attributing illness to spiritual or humoral imbalances. Hippocratic physicians emphasized natural causation and systematic observation. Galens anatomical theories dominated European medicine for over a millennium despite reliance on animal dissection rather than human cadavers.
The book explores Renaissance transformations. Vesalius corrected Galenic errors through systematic human dissection, establishing anatomy as observational science. Circulation of blood, microscopic examination of tissues, and identification of specific organs functions replaced speculative theories with empirical evidence. Yet therapeutic interventions remained limited—bloodletting, purging, and ineffective compounds persisted into the nineteenth century.
Modern medicine emerged through multiple breakthroughs. Anesthesia enabled complex surgery previously impossible due to pain. Antiseptic techniques and sterilization dramatically reduced surgical mortality. Germ theory identified microorganisms causing infectious diseases, transforming public health through sanitation and vaccination. X-rays revealed internal structures without surgery. Antibiotics conquered bacterial infections that had killed millions. Immunology, virology, and molecular biology revealed disease mechanisms at cellular and genetic levels, enabling targeted therapies.
