Therapeutic phlebotomy is a safe and simple procedure of drawing blood from a patientâs arm (similar to a regular blood donation) for the purpose of treating a disease. It involves controlled removal of blood from a vein in large volumes.
Blood-letting allowed for the control of humors in a particular part of the body. Phlebotomy was administered in two ways, via derivation or revulsion. Derivation meant letting of blood at a point close to the affected area, and revulsion meant that blood was let at the most remote point to the affected area.henever medieval medicine is mentioned in a conversation among persons of our modern age, the first uttered words usually pertain to the practice of blood-letting in the Middle Ages. It is probably due to the shocking value of such treatment as well as its eventual failure and ineffectiveness in most cases.
