Records of physicians treating the sick stretch back more than 4,500 years.However for most of this time doctors had real little knowledge and relied mainly on superstition and herbal cures.Medical science as we know it began 300 years ago,when a flowering of knowledge helped doctors understand how the body works;later; innovations such as immunization,helped cure its ills.Today medical advances save more lives then ever before,but it can be expensive and many of the world's poorest people cannot offered it.Greek doctors learned surgery by treating war wounds,but blamed the gods for any failures.Ancient roman s improved public health with clean water supply and swear system.
Asclepius And Hygieia The greek god of medicine,Asculapius may have actually bean a re al physician 3,200 nyears ago.T he roman worshipped both him as(Asculapius),and his daughter ,Hygiea,whose name gives us the word "hygiene".
FOUR HUMOURS
A Greek surgeon named galen (129-199) believed incorrectly that huaman beings were in good health only when they had a erfect balance of thir bodily fluids-their "four humours(blood,phlegm cloler and
melancholy).correspnding to physical build and certain elements .This idea dominated medicine for 1,400 years.ISLAMIC MEDICINE
Religion was powerful force in the arab world.The holy book of islam contain rules about hygiene and diet.Galen's ideas about the four humours strongly influenced early islamic medicine,but in the 13th century,the arab advanced medical knowledge when the physician Ibn-an-Nafis (1210-880made important discoveries about the circulation of the blood.
HIPPOCRATES
Greek physician hippocrates (460-37 BC)separated medicine from magic.His treatment included diets ,purgative, baths and fresh air.He was one of the first to realize that a por invironment can cause bad health.Today,trainee doctors still pledgec their dedication to patients by repeating an oath once said to by written by Hippocrates.
PREHISTORIC MEDICINE
Buried skeletons provide hints about prehistoric medical treatment.In a procedure called treplanning,early surgeon drilled their patients skulls,perhaps thinking this would let disease escape.Archaeologists have found skulls that show partical healing,so not all patients died after the operation.
