Medicine in the West

In pre-historic times people knew nothing about the causes of disease and had no concept of health care. Healing depended largely on begging for mercy from a supreme being. Organized religion appeared around 6th Century BCE, the religious believes prevented further medical progress until Ancient Greece (~ 4th Century BCE) when some people such as Hippocrates (the father of Western Medicine, Figure 01 shows him
Father of Western Medicine treating the wound of a Greek soldier) rebelled. He was the first to propose theory to explain the causes and cures of disease (in the Hippocratic Collection). The Hippocratic oath sets ethical standards for physicians. The Roman Empire became the dominant power of Eurasia in the 2nd century BCE, it initiated many medical practices to ensure that its army is fit to fight. Galen was a Greek doctor in Rome at this period of time, he stressed the importance of human anatomy in curing diseases. His mistake was to dissect the bodies of apes instead of human's. Medical progress became stagnant during Dark Age (500 - 1000 AD) after the collapse of the Roman Empire. Renaissance saw the correct human anatomy, the discovery of blood pumping heart, and the improvement in surgery. During the Industrial Revolution in the 18th and 19th Centuries there were many medical discoveries including the identification of the source for cholera (infected water), smallpox vaccination, the germ theory (illness caused by germs), and the use of anaesthetics and blood transusion in surgery. Synthetic drug started as distillation of isolates from plants in 16th Century. By the 20th Century, chemists learned to synthesize active plant components and modern laboratories are able to produce standardized and readily

available drugs. Now people are accustomed to taking a pill for everything and most doctors and their patients addressed individual symptoms instead of causes.

According to whether it can relieve pain and suffering from the patients, 11 of the branches are summarized in the following sub-sections with the name of the disease, the symptom(s), cause(s), and treatment(s) in form of a table. It is intended only as a very quick reference, the real patient should visit a doctor instead of browsing here.

See "Better Health Channel" for a complete list of all the diseases.

In June 2015, the Nature magazine commences a new on-line publication with review articles on all kinds of disease or disorder (across all medical specialties). For an up-to-date information in medical science, see "Nature Reviews Disease Primers".
