History of Bloodletting Essay

Hans von Gersdorff Feldbuch der Wundarzney (Field book of surgery) (Page 16V), 1517 The above diagram is from a medicament book published in 1517 by a German surgeon Hans von Gersdorff, showing the points of lineletting, we can see that there are nearly 50 points of bloodshed distributed in all move of the bole. The diagram besides shows a dissection of a male human eubstance with most of the organs shown, it seems that people at time or before that time already did a lot of experiments and dissections on human body trying to understand their own body and how to enshroud different illness by bloodletting. It can also be conclude that bloodletting is a very scientific way to treat illness at that time as it appears in a published medicine book, the diagram shows a quite accurate human dissection and there are so many points of bloodletting for treating illnesses.Bloodletting is a medical practice of withdrawing blood from our body by bleeding, the history of bloodletting starte d at the ancient times and found in many countries, its subject is to train the excessive or the baneful humours in our body in order to maintain health. This idea come from the time period of female as people at that time though that menstruation is a process of removing bad humours. The idea of bloodletting is reinforced by the humoral theory and research of Galen. Galen states that blood is produced in the live and is consumed in body parts, blood is not circulating and so will stagnate in different body parts. And the humoral theory of Galen state that the healthiness of our body is maintained by the humoral balance. So if there is excessive humours, we should remove them in order to maintain health. If blood is the excessive humour, bloodletting should be performed. These two idea combined together and contributed to the development of bloodletting.There are so many points of bloodletting shown in the diagram is possibly because of people at that time though that differen t diseases are caused by excessive blood stagnate in different body parts, so they perform bloodletting in different body parts in order to heal different illnesses by restoring the humoral balance.The idea of bloodletting lasts for almost 2,000 years and was disproved by William Harvey. From my point of view, Williams research disprove the theory of bloodletting in two ways. Firstly, William founds that blood is not produced in liver then used up in body parts as Galen said, but is circulating all around the body and so it will not stagnate in the body parts. Therefore bloodletting in different body part will get the same result and the theory of performing bloodletting in different body part to treat different illness is disproved.Secondly, as blood is not produced then used up, so the production rate of blood is not as fast as Galen thought. Actually, the production rate of blood in our body is quite slow and so the amount of blood is relatively constant. As the procedure of bloo dletting is to remove quite a large amount of blood, so this will weaken our body and sometimes maybe even fatal. This disprove the idea of using bloodletting to treat illness. Despite of this, the practice of bloodletting still quite common until the 1900s because of its own long history.Nowadays, bloodletting is seldom use as a flesh of scientific medical treatment already as most of the people knows about the side effects of it, but it still appears in some syndicate healing practice.Reference1.
