痘夹血泡因肺热，或紫或赤微甚别，内服凉血解毒汤，外用针刺出恶血。
【注】痘当起胀时，忽有小泡夹痘而出，渐渐长成，如白果大，毒甚由紫，毒微则赤，
皆谓之血泡。此因毒热在肺，传于皮肤，大小不一。须内服凉血解毒汤，外用银针刺破，
流出恶血，方保无恙。若不急治，听其自破，恶汁流染，痘亦因之赤烂矣！治者宜详记之。

水泡湿淫克脾经，手足稠密身面轻，内服加味保元剂，外涂胡荽官粉灵。
【注】水泡者，形大皮薄，内含一包清水。盖因湿淫之气侵克脾经，故身面俱少，手足
独密，以四肢属脾故也。须服加味保元汤，外用银针刺破，以胡荽酒调官粉涂患处，若延
迟不治，变成痒塌，则难救矣。

归宗汤（方见发热证治）
痘疹夹杂血泡是由于肺热所致，颜色或紫或赤，以此区分毒邪的轻重。内服凉血解毒汤，外用针刺排出恶血。
【注】痘疹在起胀阶段时，突然有小水泡夹杂在痘疹中长出，逐渐长大，大小如白果。毒邪重则呈紫色，毒邪轻则呈红色，都称为血泡。这是因为毒热在肺，传至皮肤，大小不一。必须内服凉血解毒汤，外用银针刺破，流出恶血，才能确保平安无事。如果不紧急治疗，听任其自行破裂，恶汁流出污染周围，痘疹也会因此变得红烂！医者应当详细记录此法。

水泡是由于湿邪过盛克制脾经所致，手足部位稠密，身体和面部较轻。内服加味保元剂，外用胡荽酒调合官粉涂抹。
【注】水泡，形状大且皮薄，内含一包清水。这是因为湿邪之气侵克脾经，所以身体和面部较少，唯独手足部位密集，因为四肢属于脾的缘故。必须服用加味保元汤，外用银针刺破，用胡荽酒调合官粉涂抹患处，如果拖延不治疗，变成瘙痒塌陷，就难以救治了。

【注】痘疹在起胀阶段时，从头到身，逐渐与痘疹一同浮起，这是气引领血载，毒邪向外发散的征象。如果头身的肉先肿，皮色赤艳而痘疮本身不肿，这是毒邪有余，不受正气制约，宜用羌活救苦汤。如果皮色淡红，是气血不足，不能拘摄毒瓦斯，宜用参归大补汤治疗。更有通身皮肤尽赤的情况，这是毒火炽盛，煎灼血分，宜用归宗汤。

归宗汤（方剂见发热证治章节）
Dacchuan mixed with blood blisters is caused by Lung heat; the color may be purple or red, distinguishing the severity of the toxin. Internally administer Liangxue Jiedu Tang (Cooling Blood and Detoxifying Decoction); externally, use needle puncture to drain foul blood.
[Note] When Dacchuan is in the distension stage, small blisters suddenly appear among the pustules, gradually growing to the size of a ginkgo nut. If the toxin is severe, the color is purple; if mild, it is red. All are called blood blisters. This is due to toxic heat in the Lung transmitting to the skin, varying in size. One must internally administer Liangxue Jiedu Tang (Cooling Blood and Detoxifying Decoction) and externally puncture with a silver needle to drain foul blood, ensuring safety. If not treated urgently and allowed to rupture spontaneously, the foul fluid will spread and contaminate surrounding areas, causing the pustules to become red and ulcerated! Practitioners should record this method carefully.
Liangxue Jiedu Tang (See formula in the section on Crusting and Scab Falling).
Water blisters result from excessive dampness overcoming the Spleen meridian; they are dense on the hands and feet but light on the body and face. Internally administer Jiawei Baoyuan Ji (Modified Tonifying Origin Formula); externally apply Huixi Guanfen Ling (Coriander and Official Powder Elixir).
[Note] Water blisters are large in shape with thin skin, containing a sac of clear fluid. This is because damp pathogenic qi invades and overcomes the Spleen meridian; thus, there are few on the body and face, but densely on the hands and feet, as the four limbs belong to the Spleen. One must take Jiawei Baoyuan Tang (Modified Tonifying Origin Decoction), puncture externally with a silver needle, and apply official powder mixed with Huixi wine (Coriander Wine) to the affected area. If treatment is delayed, turning into itching and collapse, it becomes difficult to save.
Jiawei Baoyuan Tang (Modified Tonifying Origin Decoction)
Ren Shen (Ginseng Radix), Zhu Ling (Polyporus), Ze Xie (Alisma Rhizome), Bai Zhu (Atractylodis Macrocephalae Rhizoma, stir-fried with soil), Huang Qi (Astragali Radix, honey-fried), Chi Fu Ling (Poria with Red Cortex), Gan Cao (Licorice Root, roasted).
Use Sheng Jiang (Zingiberis Rhizoma Recens) as a guide, decoct in water and take orally.
[Formula Song] Jiawei Baoyuan's effect is most swift, Ren Shen and Zhu Ling together with Ze Xie, Bai Zhu and Huang Qi with Chi Fu Ling, Gan Cao and Sheng Jiang listed together.
Huixi Jiu (Coriander Wine)
Huixi (Coriandri Fructus, chopped, 4 liang), Huang Jiu (Yellow Rice Wine, 0.5 jin).
Decoct together, do not let the qi escape, wait until warm, mix with Guan Fen (Official Powder), and apply to broken areas.
Sores have not yet distended, but flesh is swollen and floating; the skin is smooth and color bright, most worrying. If red and bright, treat with Qianghuo Jiuku Tang (Notopterygium Rescue from Distress Decoction); if pale red, seek great tonification with Shengui Dabu Tang (Ginseng and Angelica Great Tonifying Decoction). If the whole body is entirely red, the toxic heat is blazing; quickly administer Guizong Tang (Guizong Decoction) early.
[Note] When Dacchuan is in the distension stage, from head to body, it gradually rises along with the pustules; this is Qi leading and Blood carrying, with the toxin emerging outward. If the flesh of the head and body swells first, with bright red skin but the pustules themselves do not swell, this indicates excess pathogenic toxin not controlled by righteous Qi; use Qianghuo Jiuku Tang (Notopterygium Rescue from Distress Decoction). If the skin color is pale red, it indicates deficiency of Qi and Blood, unable to restrain the toxin; treat with Shengui Dabu Tang (Ginseng and Angelica Great Tonifying Decoction). Furthermore, if the entire body's skin is completely red, this indicates blazing toxic fire scorching the Blood level; use Guizong Tang (Guizong Decoction).
Qianghuo Jiuku Tang (Notopterygium Rescue from Distress Decoction)
Man Jing Zi (Vitaliae Viticis Fructus), Qiang Huo (Notopterygii Rhizoma et Radix), Niu Bang Zi (Arctii Fructus, stir-fried), Sheng Ma (Cimicifugae Rhizoma), Huang Qi (Astragali Radix, raw), Chuan Xiong (Chuanxiong Rhizoma), Lian Qiao (Forsythiae Fructus, heart removed), Jie Geng (Platycodonis Radix), Bai Zhi (Angelicae Dahuricae Radix), Fang Feng (Saposhnikoviae Radix), Ren Zhong Huang (Human Excrement Yellow).
Use He Ye (Nelumbinis Folium) as a guide, decoct in water and take orally.
[Formula Song] Qianghuo Jiuku Tang is most excellent, Sheng Ma and Chuan Xiong combined with Qiang Huo and Fang Feng, Niu Bang Zi, Huang Qi, Bai Zhi, and Lian Qiao, Man Jing Zi, Jie Geng, and Ren Zhong Huang.
