痘疹虽然表面光亮，但完全没有血色，透明得像琉璃一样，稍微擦拭就会破裂，内部全是清水，有时出血，始终没有脓液，这是因为气血无法运化毒邪所致。之后必然因声音嘶哑而死亡。如果痘疹在起胀阶段出现这种情况，应立即选取最严重的部位刺破以排出积水，然后使用实浆散：人参、黄芪、当归、鹿茸、白术、淮山药、山楂、扁豆、白芷、炙甘草，加入四十九粒黄豆。或者使用大补元煎等方剂效果更佳。
全身痘疹都凹陷，只有尾椎骨周围一圈饱满润泽，明亮如珠，就像草叶尖端的露珠一样。因为尾椎对应肾脏区域，这说明肾气强盛、精髓充足，此时急用内托的药剂，全身的痘疹就会迅速隆起恢复。
需要与前几篇的内容参照结合进行治疗。痘毒随血液排出，毒邪旺盛则血热也旺盛，所以痘疹呈现黑色。这是必死的痘症，古代方书中虽有数条记载，但总以凉血解毒为主，姑且记录在后面，以备参考使用。
刚看到皮肤之间有黑点的，使用朱砂、冰片、牛黄，或者用猪尾巴血调入人牙散，用好酒同服。
刚出来的痘点就是黑色的，使用紫草茸二三钱，用好酒调服。
另外，皮肤发青紫纹的，使用川紫草一钱，红花、荆芥、防风、牛蒡子、生地黄各八分，木香、甘草各三分，升麻五分。
另外，有黑色痕迹并结黑色痂的，使用蝉蜕五个，紫草茸一钱。
另外，黑得像煤炭，血液不红润活泼的，使用紫草、红花、生地、牛蒡子、赤芍。
另外，黑色且柔软的，是气弱而血热，使用保元汤加入红花、紫草、生地。
另外，焦黑伴有潮热烦躁的，使用小无比散三钱，加入紫草、生地、红花，磨犀角调服。
人牙散：人牙（自然脱落的）火煅存性，放入韭菜汁中淬炼，研成粉末，加入麝香五厘，穿山甲二分，用鸡冠血、葱白煎酒调服。
保元汤：人参、黄芪、当归、川芎、紫草、红花、肉桂、防风。
小无比散：滑石六两，石膏一两（煅），寒水石（煅）、郁金（用甘草水煎透，焙干）、甘草各适量
Although the variola (smallpox) lesions appear bright and lustrous, they lack any blood color, resembling clear glass; they rupture upon slight friction, containing only clear fluid inside, sometimes bleeding, but never forming pus. This occurs because Qi and Blood fail to transform and eliminate toxic pathogens. The patient will inevitably die after losing their voice. If such lesions appear during the swelling stage of the variola, immediately puncture the most severe ones to drain the fluid, then administer Shijiang San (Solid Pustule Powder): Renshen (Ginseng Radix), Huangqi (Astragali Radix), Danggui (Angelicae Sinensis Radix), Lurong (Cervi Cornu Degelatinatum), Baizhu (Atractylodis Macrocephalae Rhizoma), Huaishan (Dioscoreae Rhizoma), Shanzha (Crataegi Fructus), Biandou (Lablab Semen Album), Baizhi (Angelicae Dahuricae Radix), Zhigancao (Prepared Glycyrrhizae Radix et Rhizoma), plus 49 soybeans. Alternatively, using Dabu Yuanyuan Jian (Great Tonification for Origin Decoction) is even more effective.
The lesions on the entire body are sunken, except for a ring around the coccyx which is full, moist, and lustrous, shining like pearls, similar to dewdrops on grass tips. Since the coccyx corresponds to the Kidney region, this indicates strong Kidney Qi and abundant essence. Urgently administering internal-supporting formulas will cause the lesions all over the body to rise and recover quickly.
It is essential to refer to previous chapters for treatment guidance. Variola toxins exit with the blood; when toxins are vigorous, blood heat is also vigorous, hence the lesions turn black. These are invariably fatal cases. Although ancient texts contain several prescriptions, the primary principle is always cooling blood and detoxifying. They are recorded here for reference.
For black spots initially appearing between the skin layers, use Zhusha (Cinnabar), Bingpian (Borneolum Syntheticum), and Niuhuang (Calculus Bovis), or mix Zhuwei Xue (Tail Blood of Porcus Sus Scrofa Domestica) into Renya San (Human Tooth Powder) and take with good wine.
For lesions that are black from the outset, use Zicao Rong (Arnebiae Radix et Rhizoma) 2-3 qian, mixed with good wine for oral administration.
Additionally, for blue-purple streaks on the skin, use Chuan Zicao (Lithospermi Radix) 1 qian, Honghua (Carthami Flos), Jingjie (Schizonepetae Herba), Fangfeng (Saposhnikoviae Radix), Niubangzi (Arctii Fructus), and Shengdihuang (Rehmanniae Radix Recens) each 8 fen, Muxiang (Aucklandiae Radix) and Gancao (Glycyrrhizae Radix et Rhizoma) each 3 fen, and Shengma (Cimicifugae Rhizoma) 5 fen.
For black marks and black scabs, use Chantui (Bombyx Batryticatus) 5 pieces and Zicao Rong (Arnebiae Radix et Rhizoma) 1 qian.
For lesions as black as coal with dull, non-vibrant blood, use Zicao (Lithospermi Radix), Honghua (Carthami Flos), Shengdi (Rehmanniae Radix Preparata), Niubangzi (Arctii Fructus), and Chishao (Paeoniae Radix Rubra).
For lesions that are black and soft, indicating weak Qi and blood heat, use Baoyuan Tang (Protect the Origin Decoction) added with Honghua (Carthami Flos), Zicao (Lithospermi Radix), and Shengdi (Rehmanniae Radix Preparata).
For scorched-black lesions accompanied by tidal fever and restlessness, use Xiaowubi San (Little Peerless Powder) 3 qian, added with Zicao (Lithospermi Radix), Shengdi (Rehmanniae Radix Preparata), and Honghua (Carthami Flos), mixed with ground Xijiao (Rhinocerotis Cornu) and taken with liquid.
Renya San (Human Tooth Powder): Human teeth (naturally fallen) calcined until retaining their nature, quenched in Jiucai Zhi (Juice of Allium tuberosum), ground into powder, added with Shexiang (Moschus) 5 li, Shanjia (Manis Squama) 2 fen, mixed with Jiguan Xue (Crista Galli Sanguis) and Congbai (Scallion White) decocted in wine for oral administration.
Baoyuan Tang (Protect the Origin Decoction): Renshen (Ginseng Radix), Huangqi (Astragali Radix), Danggui (Angelicae Sinensis Radix), Chuanxiong (Chuanxiong Rhizoma), Zicao (Lithospermi Radix), Honghua (Carthami Flos), Rougui (Cinnamomi Cortex), Fangfeng (Saposhnikoviae Radix).
Xiaowubi San (Little Peerless Powder): Huashi (Talcum) 6 liang, Shigao (Gypsum Fibrosum) 1 liang (calcined), Hanshuishi (Aqua Marina), Yujin (Curcumae Radix) (decocted thoroughly in Licorice water, dried), and Gancao (Glycyrrhizae Radix et Rhizoma) each appropriate amount
