第一章双针一罐
第一节三棱针刺血
二、刺法
针刺前，针具煮沸消毒，针刺部位，常规用75%酒精消毒。右手拇、食、中指持针，左手拿位患者针刺部位，在某些穴位，需以左手作捏、按、提拿动作配合，便于找准放血点。根据病情需要，可选用下列各种刺法：
1．缓刺：用针缓慢地刺入静脉0．5一1分深，随即缓慢放血。适从于肘窝、腘窝部等处放血。
2．速刺：用针迅速刺进0．5一1分深，挤出少量血液。适用于四肢末端十二井穴和十宣穴等。
3．挑刺：用三棱针挑破细小静脉，挤出少量血液。适用于胸背部和耳后等处。儿童挑疳积，也常用挑刺。
4．围刺：围绕病痛区，肿处四周点刺，一般常配合拔火罐。
5．丛刺：用三棱针在某一较小局部，多次点刺，使之出血。丛刺多结合拔火罐。
6．散刺：又叫豹纹刺，用于点刺较宽的面积或循经点利，结合拔火罐、运走罐等方法，也可以用手拿提点刺部位出血。
7．顺利：由下向上作斜刺，在放血前可由上到下推至放血点，以除恶血为主。
8．逆刺：由上向下作斜刺，在针刺前可由针刺点向上下推揉，分推血液，然后针刺，以放邪气为主．
六、注意事项
三棱针疗法针刺时不可过深，出血也不可过多，一般出血后，要用酒精棉球擦揉按压止血。凡治疗部位都要严密消毒，防止感染。针刺出血者，可1日或隔日针1次，出血较多时，一周针2次。针刺出气者，可1日3次，以肤红为度。并常结合火罐拔吸，以肤湿为度。

第二章辨血论
第一节辨血
五、气血与经络
手太阴肺经多气少血；手阳明大肠经气血俱多
足阳明胃经多血多气；足太阴脾经少血多气
手少阴心经多气少血；手太阳小肠经多血少气
足太阳膀胱经多血少气；足少阴肾经多气少血
手厥阴心包经多血少气；手少阳三焦经多气少血
足少阳胆经多气少血；足厥阴肝经多血少气。
第二节辨血色
一、血呈深红色
针刺部位出血后，血的色泽为深红色时，从中可以判断，疾病多属于热症。
二、血呈黑红色
凡在体表刺出血后，血的色泽为深红色，可分为外伤、内伤辩证。1、外伤一般是在阿是部。多由于气血结聚所致，青紫斑痕是由于局部络脉血溢所致。2、内伤：四肢深部内伤，多因瘀血阻滞经络，头、身躯部内伤，多因恶血聚集脏腑，一般是在属该脏腑部位疼痛。
三、血呈淡红黄色
一般是在肘部、膝部关节处针刺出血，血的色泽为淡红黄色，多为风湿痹症。
四、血呈青紫色
在背部、腹部、十指等部位针刺出血，色泽为青紫色，多因寒邪入里，窜入机体，伤于脏腑机能，
第三节辨刺血时血的动态
一、出血清淡难凝
当针刺出血时，血液清淡而稀疏不易沉凝，是血虚的表现。凡刺出血为清淡者，临床上多以放气为主，在对症刺血时，血不止应禁刺。
二、出血沉凝易结
针刺出血时，血液容易沉淀并凝结，多因气虚所致，而多实证。凡此类情况，可以泻血为主，兼调气补虚。
三、出血缓慢
针刺肌肤后，出血缓慢，多需几次刺血，仍断断续续出血者，多因气血亏虚，瘀血阻于脏腑，脏腑气机衰弱，气血循环而不归经。在对症施治中，应充分掌握补泻关系，以放气活血为主。
四、出血急促
针刺肌肤后，出血急促，多为热盛。施治中，应以放气为主，兼刺血泻热。但凡有习惯性皮肤紫斑者，应禁针或慎针。
第四节辨其它
一、血挟脓汁
凡在针刺部位出现脓血，多因外伤后恶毒犯内或长久内伤化脓所致。施治中多以刺脓排毒为主，在深部脓血可采用放气活血化脓之法。
二、粘性白液
凡在四缝穴、背心、胸部、鱼际等处挑刺出白色粘性液体，多因小儿疳积、水谷运化失调，气血机能不畅，局部络脉供血不足所致。针刺四缝穴等处，可以起到调脾胃补虚损的功效。
三、白色粉质物
……此多因络脉长久瘀气、瘀血阻结，失去血脉正常循行，而在肌肤内转化成肿结。……在民间中往往用挑刺挤压除去肿结，消除后，就用一枚硬币贴于患处，然后用布包扎7天后取下，肿结自然消失。如果不用硬币贴于患处，不几日肿结会重新长起来。
四、透明性水液
……此病多为浮肿。……此证不应多泻，可配合药物治疗。
五、水珠悬罐
……这种现象多属体内寒湿过重。……凡以上现象，临床上多采用走罐法驱寒邪，留罐法泻风湿。
六、罐中气暖
…..则此种情况，是多因体内湿热过重。湿热入里，行之经络血脉，则多发于手心、脚心、背心皮肤湿润。因湿热过重常出现头痛、发热、身重而痛，腹泻食少，腰酸背痛等。……临床上泻湿热，多在手心、脚心、大椎、命门、委中、承山、脐中等处。

Selected Excerpts from Folk Bloodletting Techniques in China
By Liu Shaolin and Liu Guangrui
--------------------------------------------------------------------------------
Chapter 1: Double Needles and One Cup
Section 1: Pricking-Blood Therapy with a Three-Edged Needle
II. Needling Methods
Before needling, the needles must be sterilized by boiling, and the needling site should be disinfected routinely with 75% alcohol. The needle is held in the right hand using the thumb, index finger, and middle finger, while the left hand stabilizes the patient's needling site. At certain acupoints, the left hand performs pinching, pressing, or lifting actions to assist in accurately locating the bloodletting point. Depending on the condition, the following needling methods may be selected:
1. Slow Pricking (Huan Ci): The needle is slowly inserted into the vein to a depth of 0.5 to 1 fen, followed by slow bloodletting. This is suitable for bloodletting at the cubital fossa and popliteal fossa.
2. Rapid Pricking (Su Ci): The needle is quickly inserted to a depth of 0.5 to 1 fen, squeezing out a small amount of blood. This is applicable to the Twelve Jingwell Acupoints (Shi'er Jingxue) and Ten Xu Acupoints (Shixuan) at the extremities.
3. Lifting Pricking (Tiao Ci): A three-edged needle is used to pierce small veins, squeezing out a small amount of blood. This is suitable for the chest, back, and behind the ears. It is also commonly used for treating infantile malnutrition (Ganji) in children.
4. Surrounding Pricking (Wei Ci): Point pricking is performed around the painful area and the periphery of swelling, generally combined with cupping therapy (Ba Guan).
5. Cluster Pricking (Cong Ci): Using a three-edged needle, multiple point pricks are made in a small local area to induce bleeding. Cluster pricking is often combined with cupping.
6. Scattered Pricking (San Ci): Also known as Leopard-Skin Pricking (Bao Wen Ci), this method is used for point pricking over a wider area or along meridians, combined with cupping or moving cupping techniques. Alternatively, the skin at the needling site can be lifted and pinched to induce bleeding.
7. Smooth Pricking (Shun Ci): Oblique pricking from bottom to top. Before bloodletting, pressure can be applied from top to bottom towards the bloodletting point to expel evil blood primarily.
8. Reverse Pricking (Ni Ci): Oblique pricking from top to bottom. Before needling, massage can be applied up and down from the needling point to distribute the blood flow, then needling is performed to expel pathogenic factors primarily.
VI. Precautions
During three-edged needle therapy, needling should not be too deep, and blood loss should not be excessive. After bleeding, the site should be wiped, rubbed, and pressed with an alcohol cotton ball to stop bleeding. All treatment sites must be strictly disinfected to prevent infection. For patients undergoing bloodletting, needling can be performed daily or every other day; if blood loss is significant, twice a week is appropriate. For qi-releasing needling, it can be performed three times a day until the skin turns red. It is often combined with cupping suction until the skin becomes moist.

Section 3: Cupping Therapy
Chapter 2: Theory of Differentiating Blood
Section 1: Differentiating Blood
The Hand-Taiyin Lung Meridian has abundant Qi and little Blood; the Hand-Yangming Large Intestine Meridian has abundant Qi and Blood.
The Foot-Yangming Stomach Meridian has abundant Blood and Qi; the Foot-Taiyin Spleen Meridian has little Blood and abundant Qi.
The Hand-Shaoyin Heart Meridian has abundant Qi and little Blood; the Hand-Taiyang Small Intestine Meridian has abundant Blood and little Qi.
The Foot-Taiyang Bladder Meridian has abundant Blood and little Qi; the Foot-Shaoyin Kidney Meridian has abundant Qi and little Blood.
The Hand-Jueyin Pericardium Meridian has abundant Blood and little Qi; the Hand-Shaoyang Sanjiao Meridian has abundant Qi and little Blood.
The Foot-Shaoyang Gallbladder Meridian has abundant Qi and little Blood; the Foot-Jueyin Liver Meridian has abundant Blood and little Qi.
Section 2: Differentiating Blood Color
I. Blood Appears Dark Red
After bloodletting at the needling site, if the blood color is dark red, it indicates that the disease mostly belongs to Heat Syndromes (Re Zheng).
II. Blood Appears Black-Red
If the blood color is black-red after surface bloodletting, it can be differentiated into External Injury (Wai Shang) and Internal Injury (Nei Shang). 1. External injuries usually occur at Ashi points (Ah Shi). They are mostly caused by the accumulation of Qi and Blood stagnation; blue-purple spots are due to blood extravasation from local collateral vessels. 2. Internal injuries: Deep internal injuries in the limbs are mostly due to blood stasis blocking the meridians; internal injuries in the head and trunk are mostly due to evil blood accumulating in the Zang-Fu organs, causing pain in the areas corresponding to those organs.
III. Blood Appears Pale Red-Yellow
When bloodletting is performed at the elbow or knee joints, if the blood color is pale red-yellow, it mostly indicates Wind-Damp Bi Syndrome (Feng Shi Bi Zheng).
IV. Blood Appears Blue-Purple
If the blood color is blue-purple after bloodletting at the back, abdomen, or ten fingers, it is mostly due to Cold Pathogens entering the interior, invading the body, and damaging Zang-Fu organ functions.
Section 3: Differentiating Blood Dynamics During Bloodletting
I. Dilute Blood That Is Difficult to Coagulate
When blood is dilute, sparse, and difficult to settle or coagulate upon needling, it indicates Blood Deficiency (Xue Xu). In clinical practice, when blood is dilute, releasing Qi is prioritized. If bleeding does not stop during symptomatic bloodletting, needling should be prohibited.
II. Dense Blood That Easily Clots
When blood easily settles and clots upon needling, it is mostly due to Qi Deficiency (Qi Xu) presenting as Excess Syndromes. In such cases, draining blood is prioritized, accompanied by regulating Qi and tonifying deficiency.
III. Slow Bleeding
If bleeding is slow after needling the skin, requiring multiple sessions with intermittent bleeding, it is mostly due to Qi and Blood deficiency, blood stasis blocking the Zang-Fu organs, weak Zang-Fu Qi mechanism, and abnormal Qi and Blood circulation failing to return to the meridians. In symptomatic treatment, the relationship between tonification and purgation must be fully grasped, prioritizing releasing Qi and activating Blood.
IV. Rapid Bleeding
If bleeding is rapid after needling the skin, it mostly indicates Excessive Heat (Re Sheng). Treatment should prioritize releasing Qi, supplemented by bloodletting to drain heat. However, needling should be prohibited or used with caution in patients with habitual purpura.
Section 4: Differentiating Other Substances
I. Blood Mixed with Pus
If pus and blood appear at the needling site, it is mostly due to toxic pathogens invading internally after external injury or chronic internal injuries turning into suppuration. Treatment prioritizes puncturing pus to detoxify. For deep pus and blood, methods to release Qi, activate Blood, and promote suppuration may be used.
II. Viscous White Fluid
If viscous white fluid is extracted by lifting pricking at the Si Feng Acupoint (Sifeng), back center, chest, or Yu Ji, it is mostly due to infantile malnutrition, impaired digestion of food and fluids, poor Qi and Blood function, and insufficient blood supply to local collaterals. Needling Si Feng can regulate the Spleen and Stomach and tonify deficiencies.
III. White Powdery Substance
...This is mostly due to long-term Qi stagnation and Blood stasis blocking collaterals, disrupting normal blood circulation, and transforming into nodules within the skin... In folk practice, these nodules are often removed by lifting pricking and squeezing. After removal, a coin is placed on the lesion, wrapped with cloth for 7 days, and then removed, causing the nodule to disappear naturally. If a coin is not used, the nodule will reappear in a few days.
IV. Transparent Fluid
...This condition is mostly edema... This syndrome should not be drained excessively; it can be treated with herbal medicine.
V. Water Droplets Hanging on the Cup
...This phenomenon mostly indicates excessive Cold-Dampness in the body... Clinically, moving cupping is used to dispel Cold Pathogens, and stationary cupping is used to drain Wind-Damp.
VI. Warm Air in the Cup
...This situation is mostly due to excessive Damp-Heat in the body. When Damp-Heat enters the interior and travels through the meridians and blood vessels, it often manifests as moisture on the palms, soles, and back. Excessive Damp-Heat often causes headache, fever, heavy and painful body, diarrhea, poor appetite, sore waist and back, etc.... Clinically, to drain Damp-Heat, needling or cupping is often performed at the palms, soles, Dazhui (GV14), Mingmen (GV4), Weizhong (BL40), Chengshan (BL57), and Shenque (CV8).

Chapter 4: Common Extra-Meridian Acupoints for Bloodletting
Chapter 5: Effective Prescriptions for Common Diseases Using Bloodletting
Section 1: Emergency Bloodletting
There are many causes of coma, such as brain diseases or poisoning. In severe cases, there is no response to strong stimuli, and consciousness is completely lost. There are also many causes of shock, clinically manifesting as pale complexion, cold sweat, cold limbs, cyanotic lips, decreased blood pressure, fine and forceless pulse, and consciousness disorders.

VII. Snake and Insect Bites, Rabies Bites
After being bitten by a venomous snake, quickly tie a band or cloth strip tightly above the wound (about 3-6 cm) to prevent venom from spreading upward, and immediately perform bloodletting treatment.
[Treatment]
Use a three-edged needle or plum-blossom needle to bleed the affected area bitten by the venomous snake, squeezing manually or using cupping suction.
During bloodletting, keep the affected limb low. After needling, push and squeeze downwards from above to facilitate the expulsion of venom.
[Folk Method]
After being bitten by a venomous snake, the patient can immediately cut the affected limb with a small knife or sharp object, then quickly suck the blood with their mouth or squeeze it out by hand.
[Ancient Prescription]
