In the case of the disease of the body surface, pricking and releasing the blood can directly reach the disease, directly attacking the evil and going straight to its ligaments, which is far more effective than drug treatment. For example, drug treatment of varicose veins in the lower extremities is like scratching an itch, but we have received good results with the use of fire acupuncture. For the deeper ligament disease in the body, drug treatment is better than acupuncture. However, since the meridians are connected and the internal organs of the body are related, bloodletting by pricking the meridians on the body surface is also helpful in treating the internal meridian diseases. If the blood is not properly used, it can consume the qi and hurt the yin and move the blood. If it is supplemented by acupuncture, the amount of medicine can be reduced to achieve the purpose of reducing the toxic side effects of drugs. For those who are weak and intolerant to medicine, acupuncture is also a good way. Blood pricking is not simply to remove blood stasis in the body’s surface veins, but also has many other therapeutic effects. 1, reduce fever and fire: fever, Chinese medicine believes that there are two main conditions, one is Yang Sheng fever, one is Yin deficiency fever. In addition, there is also Qi deficiency fever. The effect of stabbing blood to reduce fever is mainly applicable to Yang Sheng fever, because Yang Sheng is bound to lead to blood Sheng. Yang Sheng fever is mostly caused by external evil, and bloodletting therapy is good for reducing fever due to external wind-heat, heat and toxin congestion, and heat entering the blood. Bloodletting can reduce the blood prevalence to alleviate the heat in the body, thus playing a role in reducing fever. According to Chinese medicine, “excess qi is fire”. Excessive emotion can turn fire, and spicy and stimulating, fatty and oily food can turn fire. If the stomach fire is too much, gum swelling and pain can occur; heart fire can appear on the inflammation of the mouth and tongue sores, restlessness, and even fever delirium; liver fire may appear on the inflammation of irritability, fire eyes, dizziness and other symptoms. The Qi of the human body is based on blood, and at the same time goes in and out with the blood. Forcing the blood out by pricking the ligaments can release the excessive Yang Qi, thus improving the Yang state and bringing the Qi and blood of the body into balance, thus pricking the blood has a diarrhea effect. As for Yin deficiency and Qi deficiency fever, this method is generally not suitable. 2, pain-relieving effect: Chinese medicine believes that “if it passes, it doesn’t hurt, if it hurts, it doesn’t pass”, which means that any disease with painful symptoms must have a blockage in the relevant meridians. Stabbing the blood can directly force the blood out, drain the blood stasis and clear the meridians, so the pain can stop immediately. Many acute clinical conditions, such as sore throat and migraine, can be treated satisfactorily with bloodletting therapy. 3, detoxification effect: blood pricking is very effective in treating diseases that are caused by the internal movement of poisonous evil when the body is deficient in positive energy and dysfunction, such as “red silk boils” and sores caused by the infiltration of poisonous evil. Bloodletting not only makes the invading or endogenous poisonous evil discharged with the blood, but more importantly, it restores the body’s function to normal by regulating the blood and regulating the qi, so as to inhibit the regeneration and spread of poisonous evil. 4.Anti-itching effect: “itch” is a symptom that the ancients believed to be a manifestation of wind and qi existing in the blood vessels, thus the treatment principle of “treating the wind first by treating the blood, and the wind will be extinguished when the blood is flowing”. Pricking the blood is to “regulate the blood and regulate the qi”, and the blood flow will have nothing to keep the “wind” qi, thus achieving the effect of wind and stopping itching. 5.Anti-swelling effect: “swelling” is mostly caused by Qi stagnation and blood astringency, and stagnation of meridians. Bloodletting can directly exclude the local meridians “Ivana Chen” of qi and blood and disease, so as to promote the smooth flow of meridians without obstruction, and naturally achieve the purpose of swelling. 6, the treatment of numbness: Chinese medicine believes that some numbness symptoms are due to a deficiency of qi can not be handsome blood to the extremities. Bloodletting treatment of numbness, is guided by the theory of “blood flowing through the qi”, with a three-pronged needle or milli-needle into the acupuncture point of the affected limb, releasing a small amount of blood, can encourage the qi to make blood flow to the extremity, and the numbness will stop. 7, anti-vomiting effect: nausea, vomiting mostly belong to the stomach heat or liver qi transverse offense stomach or food stagnation. Blood pricking therapy can diarrhea heat and calm the liver rebellion, and help dredge the stomach and internal organs to help digestion. 8.Stopping diarrhea: Blood pricking therapy can treat the heat diarrhea caused by the accumulation of food and heat in the intestines and stomach, or the diarrhea caused by the epidemic of the time, which is caused by the indistinguishability of the clear and turbid, etc. The mechanism is to lower the heat in the small intestine by diarrhea, and play a role in raising the clear and lowering the turbid. 9, wake up and save the soul: clinical application of blood pricking therapy to treat coma, convulsions, epilepsy and heat stroke and other critical illnesses, simple and effective. The “Qiankun Sheng interval” has recorded: “Where the middle school wind fall, fainting, phlegm and saliva congestion, unconsciousness, teeth closed, medicine water not down, urgent prick the finger twelve well points with a three-pronged needle, when to remove the bad blood. Also treats all the violent death of evil, unconsciousness, and colic cholera, is the secret of reviving the dead.” It can be seen that the ancients mostly used blood pricking therapy for first aid treatment. These therapeutic effects of blood pricking are based on the theory of meridians and qi and blood in Chinese medicine, which are inseparable. Professor He Puren, a master of Chinese medicine, proposed the doctrine of “moving qi with blood” and “bringing qi with blood”, and elevated the bloodletting method to an important method of the three methods of acupuncture and moxibustion – the “strong method”. The “strong-passage method” is to achieve multi-faceted therapeutic effects through dexterous techniques, appropriate bleeding volume, forcing the blood out, strong pricking, and fast, so that the evil will come out with the blood, eliminating stasis and opening up the closed channels, unblocking the veins and collaterals, making the meridians and blood flow smoothly, and thus achieving multi-faceted therapeutic effects. Stabbing blood not only releases blood stasis, but also stimulates the blood vessel walls, which are rich in nerves and some have endocrine cells, so stimulating blood vessels also has a neuroendocrine regulating effect, and its specific mechanism deserves further study.
