The detoxification effect mentioned in traditional Chinese medicine refers to the syndrome that occurs when the body is unable to resist the poison due to its own dysfunction under pathological conditions, such as the "red silk boils" caused by the excessive poison fire, and the poison and evil infiltration, bloodletting can not only make the poison that invades the body be discharged with the blood, but more importantly, through the effect of "regulating blood and regulating qi", the human body functions can return to normal, so as to inhibit the expansion and regeneration of the disease.
Traditional Chinese medicine believes that fiery internal disturbance can cause a variety of symptoms, often manifested as irritability, limb pain and swelling, irritability, and even fever, dizziness, and other symptoms. Phlebotomy therapy can directly make the fiery evil expel with the blood, which is suitable for a variety of heat syndromes.
Swelling and pain are mostly caused by qi stagnation and blood astringency, which makes the meridians stagnate. Bloodletting can directly eliminate the stagnant qi and blood and disease in the local meridians, promote the unobstructed meridians, and achieve the purpose of reducing swelling.
Itching is the manifestation of the existence of wind evil in the blood, so there is a treatment principle of "treating the wind first and treating the blood, and the blood and wind will destroy itself". Bloodletting is to regulate blood and regulate qi, so that the blood flow smoothly and the wind evil has nothing left, so as to achieve the effect of dispelling wind and relieving itching.
Qi deficiency cannot reach the end of the four ends, or blood deficiency is lost in nourishment, and numbness often appears.
