Long History of Blood-letting for Healing

After 22 years as an RN, I now write about medical issues and new medical advances. Diet, exercise, treatment, and lifestyle are important.


Venipuncture by a Phlebotomist

Phlebotomy, as it is practiced today, is the art of drawing blood via a vein puncture to draw blood for various tests ordered by physicians. It is typically completed by a qualified phlebotomist, a registered nurse or other medical staff.

The blood lets a doctor evaluate a patient's health. Everything from how well various organs are functioning to evaluating an infection is the purpose of the blood test. Blood-letting has been almost totally abolished, although leeches are sometimes used in special circumstances.

History of the Egyptians

The ancient art of phlebotomy dates back three thousand years as the practice began with the Egyptians in 1000 B.C. Egyptian history records blood-letting as a treatment for variety of treatments, even though it was carried out in a rather barbaric way.

The only conceivable conditions where blood-letting might be useful is with the diseases of severe hemochromatosis which causes the body to retain too much iron, and it results in primary thrombocythemia. It is a disease that causes the body to produce too many red blood cells or platelets. Nevertheless, the practice was used by the Romans and Greeks throughout the Middle Ages.

Blood-letting was believed to drive out evil spirits; therefore, the procedure was performed by a priest, which was also a physician at that time. Men believed that disease was a curse.


During the lifetime of Hippocrates (460 A.D. to 377 B.C.) beliefs changed. Hippocrates utilized careful clinical observations to recognize the symptoms of particular diseases, and the concept of body humors was developed at this time.

Body humors included blood, phlegm, yellow bile and black bile. Hippocrates believed the humors must be in perfect balance for an individual to have good health. Thus, an imbalance was treated by blood-letting. This new concept eventually stopped people from believing that disease was caused by a curse.

Points in the Body for Blood-letting


Blood-letting in Greece by Galen

In Greece, Galen of Pergamon, a prominent Greek physician, surgeon and philosopher discovered that not only veins had blood, but also arteries, which they had previously thought to be filled with air. He also believed in the humoral balance, plus it was commonly believed that blood did not circulate through the body.

They thought it stagnated in the extremities. Treatment consisted of giving the patient an emetic to induce vomiting, or they would remove excess blood. Galen developed a rather complex system of how much blood should be removed and from what areas of the body, as shown on the adjoining picture. He believed that blood should be drained close to the diseased area of the body.

Other Beliefs in the Middle Ages

In the 1400’s, astrology also played a role in blood-letting, as signs of the zodiac denoted various body parts. The planets had to be in the correct alignment in order for the procedure to be completed.

Through the centuries various religions also played a role in phlebotomy. For instance, the Talmud specified blood-letting should be done on specific days of the week and month, while Christianity had some similar guidelines. Islamic leaders also believed blood-letting was very useful for fevers.

Blood-letting in England in the 19th Century

As late as the early 19th century, blood-letting was practiced in England, even though it was starting to become less popular. It was still actually considered preventive medicine by many people.

Physical signs that were thought to require blood-letting included redness, swelling, skin that was warm to the touch and any sign of pus.

The treatment consisted of a surgeon making multiple cuts on the body while the blood drained into a bowl. The treatment was stopped when the patient felt faint, as this was considered an indication to stop treatment.

There are no records as to the number of people that died from these procedures.

1938 Barber Pole



At this time, many barber-surgeons performed blood-letting, minor surgeries, amputation of limbs and dental work, all in addition to cutting hair. The red and white barber poles were designed during this time period, with the red stripe indicating blood and the white represented a tourniquet.

Blood-letting in the United States

The practice of blood-letting was also used in the United States and practiced by the Pilgrims. In fact, President George Washington’s death was probably due to blood-letting. Apparently, he had a throat infection, and the physician drained nine pints of blood to treat the infection. He died shortly thereafter, which is hardly surprising as the body typically holds ten pints of blood.

It is difficult to believe that such a practice was carried on until the 1900s. and in some cases is still practiced in a slightly different manner today by using leeches.

In 2004, the FDA approved the use of medicinal leeches, which are used to help heal certain types of wounds and to improve circulation in blocked blood veins. The leeches used in medicine are raised in fresh water.

Medieval Medicine: Everything You Need To Know


Blood-letting has a long, interesting history. Of course, it is now a sterile procedure performed by a phlebotomist using vacuum tubes to the collect the blood samples.

There are still some areas of medicine that still find blood-letting useful by the use of the medicinal leeches. The long history of phlebotomy is very interesting as medical science evolved through the centuries.

Hi Randy,

Your remarks are so true. Blood letting apparerently had no guidelines during George Washington's life. I appreciate your comments.

Randy Godwin from Southern Georgia on April 24, 2020:

Interesting article, Pam. I knew GW died from bloodletting, but not they drained almost all of his blood from his body.

If they'd only used leeches instead George may have been around a bit longer.

Pamela Oglesby (author) from Sunny Florida on April 24, 2020:

Hi Peggy,

I thought George Washington's experience was good for this article. I think it is interesting how blood letting was apparently helpful in history for some diseases but not poor old George.

I appreciate your comments as always, Peggy.

Peggy Woods from Houston, Texas on April 24, 2020:

It is amazing how some of these theories were used in the past, and probably did more harm than good. I had never heard that about George Washington.

Pamela Oglesby (author) from Sunny Florida on June 29, 2013:

Mary, I think that is an important as some people are surely more skilled than others. This hub was more about the history of blood letting and I discovered several things I had not known before. I appreciate your comments.

Mary Hyatt from Florida on June 28, 2013:

I was a Phlebotomist while waiting to take my Medical Technology exam to become certified. I enjoyed the work a lot. The pay was not great, but I liked to think my job was important.

Voted UP and shared.

Pamela Oglesby (author) from Sunny Florida on July 15, 2012:

teaches, i am grateful for those good phlebotomists that can take a blood sample where it isn't painful. Thanks for your comments.

Dianna Mendez on July 14, 2012:

I cringe at the sight of a needle when I go to the Dr.'s office, but it does have it's benefits in healing. I have learned something new today on this procedure. I am thankful for those who do this for a career and help us to endure the pain!

Pamela Oglesby (author) from Sunny Florida on July 11, 2012:

unknown spy, I'm glad you enjoyed the hub. Thanks for your comment.

whowas, I am also delighted about the current methods. I appreciate your comments.

whowas on July 11, 2012:

Thanks for that interesting hub. I hadn't realized quite how far back the practice went. I am delighted that phlebotomy is now a safe, sterile, clinical practice and not left to the barbershop to handle!

Life Under Construction from Neverland on July 11, 2012:

this is very interesting Pamela. I've been hooked to your hub reading the history of phlebtomy.

Pamela Oglesby (author) from Sunny Florida on July 11, 2012:

drbj, Cute rhyme. I don't like the idea of leeches either. Thanks for your comments.

Suzette, I'm glad you enjoyed the history of phlebtomy. I remember reading the Laura Wilder books when I was a child and the kids were in a creek where leeches latched onto their ankles. I was horrified! I appreciate your comments.

Suzette Walker from Taos, NM on July 10, 2012:

This is quite interesting. I had no idea bloodletting started with the Egyptians. I am so glad I live in modern times and doctors and nurses for the most part know what they are doing! And, I am not into leeches. I remember hiking through some water or swampy area one time and had to pull leeches off my legs. It was awful! Those things are little blood suckers! Thanks for the phlebotomy lesson!

drbj and sherry from south Florida on July 10, 2012:

It's good that the practice of phlebotomy has evolved, Pamela. Otherwise, to the doctor I would beseech,

Please, do use anything but don't use the leech!

Fascinating information, m'dear.

Pamela Oglesby (author) from Sunny Florida on July 10, 2012:

TToombs, I think we all wonder when we are going to get out of the doctor's office! I'm glad you enjoyed the hub and I appreciate your comments.

Terrye Toombs from Somewhere between Heaven and Hell without a road map. on July 10, 2012:

Very interesting, Pamela. I guess I never thought there would be a history behind getting poked with a needle. I'm too busy wondering when the heck I'm gonna get outta the doctor's office! :) Great information. VUM! :)
