久热也。疳热亦久，但兼面黄吃炭土，鼻下烂也。
〔无〕小儿积热者，表里俱热，遍身皆热，颊赤口干，小便赤，大便焦黄，先以四顺、清凉饮子利
动脏腑，则热去。既去复热者，内热已解，而表热未解也，当用惺惺散、红绵散加麻黄微发汗，表热乃去。
表热去后，又发热者何也？世医到此，尽不能晓。或再用凉药，或再解表，或以谓不可医，误致夭伤
者甚多。此表里俱虚，气不归元，而阳浮于外，所以再发热，非热证也。只用六神散入粳米煎，和其胃
气，则收阳归内，身体便凉。热重者，用银白散。
清凉饮子 每服二钱，薄荷三钱，同煎。（方见治寒热法。）惺惺散（方见痘疹门。）
红绵散
白僵蚕（炒，二两） 天麻（生用，一两） 天南星（切薄片，油浸黄，二两） 苏木节（另研，二两半）
上为末，每服一钱，水一小盏，入红绵少许，同煎至六分，温服。凡小儿风热，头目不清，并宜服
之。若伤寒有表证发热者，每服入去节麻黄末五分；有里热心燥渴者，入滑石末半钱，同煎服之。
六神散

上细末，面糊丸粟米大，煎桃枝汤下。一 儿五七丸。五七岁二三十丸，未 儿二三丸，临卧服。
栀豉饮子 治小儿蓄热在中，身热狂躁，昏迷不食。
栀子仁（七枚） 豆豉（半两）
上用水三盏，煎至二盏，看多少服之无时。或吐不吐，立效。
久热（长期发热）。疳热（因疳积引起的发热）也是长期的，但兼见面色发黄、喜欢吃炭土或泥土、鼻孔下方溃烂等症状。
〔无〕小儿积热证，表现为表里俱热，全身发热，两颊发红，口干，小便颜色深红，大便焦黄。治疗时，先用四顺饮和清凉饮子通利脏腑，使热邪随二便排出，则热势可退。如果热退之后又复发，说明内热已经解除，但表热尚未解除，应当使用惺惺散、红绵散加入麻黄轻微发汗，表热才能去除。
表热去除后，再次发热是什么原因呢？世间的医生到了这一步，全都不能理解。有的再用凉药清热，有的再解表发汗，或者认为无法医治，导致许多患儿误治夭折的很多。这是因为此时表里都虚，气不归根，阳气浮越于外，所以再次发热，这并非真正的热证。只需使用六神散加入粳米煎服，调和胃气，就能收敛浮阳回归体内，身体自然变凉。热势重的，使用银白散。

Prolonged fever (Chronic fever). Gan heat (Heat caused by gan syndrome) is also prolonged, but accompanied by yellowish complexion, pica for charcoal or soil, and erosion under the nose.
[Wu] In pediatric accumulated heat syndrome, there is heat in both the exterior and interior, with generalized body heat, flushed cheeks, dry mouth, dark red urine, and scorched yellow stool. Initially, use Sishun Yin (Four Compliance Decoction) and Qingliang Yinzi (Cooling Drink) to purge the zang-fu organs; once the heat is expelled through bowel movements and urination, the fever will subside. If the fever recurs after subsiding, it indicates that the interior heat has been resolved, but the exterior heat remains unresolved. In this case, Xingxing San (Xingxing Powder), Hongmian San (Red Silk Powder), plus Mahuang (Ephedrae Herba) should be used to induce mild sweating, so that the exterior heat may be eliminated.
Why does fever recur after the elimination of exterior heat? Physicians of the world often fail to comprehend this stage. Some administer cooling medicines again, some attempt to release the exterior again, while others deem it incurable, leading to many cases of mismanagement and premature death. This occurs because both the exterior and interior are deficient, Qi fails to return to its origin (Yuan), and Yang floats outward. Therefore, the recurrent fever is not a true heat syndrome. One should only use Liushen San (Six Deities Powder) with Jingmi (Oryza Sativa Semen, Rice Grain) decocted together to harmonize Stomach Qi, thereby drawing floating Yang back inside, resulting in the cooling of the body. For severe heat, Yinbai San (Silver White Powder) is used.
Qingliang Yinzi: Take 2 qian of Bohe (Menthae Haplocalycis Herba, 3 qian), decoct together. (Formula see section on treating chills and fever.) Xingxing San (Formula see section on smallpox and rashes.)
Hongmian San:

Grind all into fine powder. Take 1 qian per dose, with one small cup of water, add a little Hongmian (Red Silk), decoct together until reduced to 6 fen, and take warm. It is suitable for any pediatric wind-heat causing unclear head and eyes. If there is exterior heat due to Shanghan (Cold Damage) with exterior signs, add 5 fen of Mahuang (Ephedrae Herba, without nodes) powder per dose; if there is interior heat with dry mouth and thirst, add 0.5 qian of Huashi (Talcum) powder per dose, decoct together and take.
Liushen San:
Renshen (Ginseng Radix et Rhizoma), Baifuling (Poria, white part), Ganshanyao (Dioscoreae Hypoglaucae Rhizoma, dried), Baizhu (Atractylodis Macrocephalae Rhizoma), Baibiandou (Phaseoli Multiflori Semen), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried). Each in equal proportions.
Grind into fine powder. Take one large qian per dose, with one small cup of water, one jujube, and two slices of ginger, decoct together until reduced to 5 fen, and take. This formula has many applications: add Fuzi (Aconiti Lateralis Radix Preparata) for cold stomach, add Tianma (Gastrodiae Rhizoma) for wind syndromes, add Yingsuke (Papaveris Pericarpium) for dysentery.
Yinbai San:
Ganshanyao (Dioscoreae Hypoglaucae Rhizoma, dried), Baizhu (Atractylodis Macrocephalae Rhizoma), Baifuling (Poria, white part) (each 0.5 liang), Renshen (Ginseng Radix et Rhizoma), Baibiandou (Phaseoli Multiflori Semen), Zhimu (Anemarrhenae Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried), Shengma (Cimicifugae Rhizoma) (each in equal proportions).

Zhichi Yinzi (Gardenia and Fermented Soybean Drink): Treats pediatric retained heat in the middle jiao, characterized by body heat, mania and restlessness, coma, and refusal to eat.
Zhizi Ren (Gardeniae Fructus Seed, 7 pieces), Douchi (Sojae Seminis Preparatum, half liang).
