Class 12th Biology Chapter-08: Human Health and Disease

For a long time, health was considered a state of body and mind where there was a balance of certain ‘humour’. This is what early Greeks like Hippocrates as well as the Indian Ayurveda system of medicine asserted. It was thought that persons with ‘black bile belonged to hot personalities and would have fevers. This idea was arrived at by pure reflective thought. The discovery of blood circulation by William Harvey using the experimental method and the demonstration of normal body temperature in persons with black bile using a thermometer disproved the ‘good humour’ hypothesis of health.
