Hemorrhage in traditional Chinese medicine refers to letting a certain amount of blood flow out from some parts of the human body in a specific way. This method originated from ancient medicine, and people think that it can reduce the blood concentration in the body, help eliminate viruses and toxins in the body, and thus improve human immunity.

Although bloodletting has a certain therapeutic effect, such as regulating blood vessels, dredging meridians and expelling toxins, Chinese medicine experts point out that bloodletting is not a panacea for all diseases and needs to be carried out under the guidance of a doctor. At the same time, attention should be paid to maintaining hygiene and disinfection during bloodletting treatment to avoid infectious diseases.

Although bloodletting has a history of thousands of years in Chinese medicine, it is no longer a common treatment in modern medicine. Modern medicine pays more attention to the treatment of diseases through drugs, surgery, physical therapy and other means, while bloodletting is generally only used under very special circumstances and must be carried out under strict medical conditions.
