夫人之有津液,犹天之有雨露,海之有潮汐也。天无雨露则旱,海无潮汐则涸,人
无津液则渴,甚至痘后变症丧亡。然若心胃间有热,而火炎于上,乃少津液者,必主烦
燥喘渴之疾。若脏腑有热而火益于下,乃少津液者,必主狂叫闭塞之疾。若脾热而少津
液则渴泻;肺热而少津液则暖嗽;肝热而少津液,则眼羞明;若风热攻破咽喉,而少津
液,则乃音哑;若用药发举太过而少津液;则乃溃乱;若骨肉虚而少津液,则肉 筋抽,骨
节疼痛。治法贵分虚实,而大略不外乎除热生津二者而已。然更有釜下无火,而
锅盖干燥者,当用水中补火之法,尤为生津液之源也。
诸燥扰狂越,皆属于火。然痘后狂叫喘呼之症有二,或因热毒尚存,不得发越者。
治宜清凉解毒,或从其势而发之;或因脏腑热燥而无津液者,治宜微加利水,以导心
热,盖心火降,则肾水生而诸热自退,又当兼用清热滋阴之药。若纯利其水,则水大而燥热益甚矣。
凡当痘后,疮疤柔嫩而未实,肠胃气弱而未强,外宜谨避风寒,内宜调理饮食,犯
时微若秋毫,成病重如山岳,即根据法亦不宜太迟太早,太早则瘢嫩易风,太迟则皮燥生
疮,故必须迟月余,方煎荆芥及榆槐柳艾叶汤浴之,忌服升麻朴不入黄斩黄之剂,及食
密水、西瓜,柿、梨、栗、橘、柑子、白果、酒糟、芥菜、葱、韭、薤、蒜,獐、兔、鸡、鹅、
羊、牛鲜鱼、生冷等物。所宜食者,腰子、猪肉、圆眼、胡桃、莲肉、红枣、淡齑、干菜类,其
甘甜之物,亦不可恣口、恐成口疳也。
The body's Jin-Ye (Body Fluids) are to humans what rain and dew are to the sky, or tides are to the sea. If the sky lacks rain and dew, there is drought; if the sea lacks tides, it dries up; if a person lacks Jin-Ye (Body Fluids), they become thirsty, and in severe cases, may suffer from complications after smallpox/varioloid (Dou-Zheng) leading to death. However, if there is heat in the Heart and Stomach causing Fire to flare upwards, resulting in deficient Jin-Ye (Body Fluids), one will inevitably suffer from irritability, panting, and thirst. If there is heat in the Zang-Fu organs causing Fire to intensify downwards, resulting in deficient Jin-Ye (Body Fluids), one will inevitably suffer from manic shouting and obstruction/closure. If the Spleen has heat and Jin-Ye (Body Fluids) are deficient, there will be thirst and diarrhea; if the Lungs have heat and Jin-Ye (Body Fluids) are deficient, there will be coughing; if the Liver has heat and Jin-Ye (Body Fluids) are deficient, there will be photophobia (aversion to light); if Wind-Heat attacks the throat and Jin-Ye (Body Fluids) are deficient, hoarseness will occur; if excessive use of diaphoretic or ascending drugs leads to deficient Jin-Ye (Body Fluids), chaotic disarray will result; if the flesh and bones are deficient and Jin-Ye (Body Fluids) are lacking, muscle twitching and tendon contraction, along with joint pain, will occur. Treatment values distinguishing deficiency and excess, but generally does not go beyond clearing heat and generating fluids. Furthermore, there is the case where there is no fire under the cauldron (Kidney Yang Deficiency), causing the lid to dry out (failure of fluid vaporization); in this case, the method of "supplementing fire within water" should be used, which is the true source of generating Jin-Ye (Body Fluids).
All conditions involving dryness disturbing the spirit and manic hyperactivity belong to Fire. However, there are two types of manic shouting and panting after smallpox/varioloid (Dou-Zheng): one is due to residual Heat-Toxin that cannot be vented. Treatment should employ cooling and detoxifying methods, or follow the pathogenic trend to vent it. The other is due to heat-dryness in the Zang-Fu organs and lack of Jin-Ye (Body Fluids). Treatment should mildly employ diuretic methods to guide Heart-Heat downward, for when Heart-Fire descends, Kidney-Water is generated, and various heats recede naturally; at this time, heat-clearing and Yin-nourishing herbs should also be used. If water is purely and strongly drained, although water volume increases, dryness-heat will worsen.
After smallpox/varioloid (Dou-Zheng), when the scabs are tender and not yet solidified, and the Qi of the Intestines and Stomach is weak and not yet strong, one should carefully avoid Wind-Cold externally and regulate diet internally. Violating these precautions initially causes symptoms as slight as an autumn hair tip, but once illness sets in, it becomes heavy as a mountain. Even following correct treatment principles, timing should not be too early or too late. Too early makes tender scabs susceptible to Wind; too late causes skin dryness and sores. Therefore, one must wait over a month before bathing with decoctions of Schizonepeta (Jing-Jie), Elm (Yu), Locust Tree (Huai), Willow (Liu), and Mugwort (Ai) leaves. Decoctions containing Ephedra (Sheng-Ma - *Note: Shengma is Cimicifuga, often grouped with ascending herbs*), Atractodes (Hou-Po), and Rhubarb (Da-Huang) that ascend or purge should be avoided. Foods such as honey water, watermelon, persimmon, pear, chestnut, orange, mandarin, ginkgo, wine lees, mustard greens, green onion, leek, Welsh onion, garlic, muntjac, rabbit, chicken, goose, sheep, cow, fresh fish, and raw/cold foods should be avoided. Suitable foods include pork kidney, pork meat, longan, walnut, lotus seed, red date, light salted vegetables, and dried vegetables. Sweet foods should not be consumed excessively, lest they cause mouth ulcers (Kou-Gan).
