治肺有劳病,薄受风寒即喘嗽,冬时益甚者。
生箭 (四钱) 生石膏(四钱捣细) 净蜂蜜(一两) 粉甘草(二钱细末)
生怀山药(三钱细末) 鲜茅根(四钱,锉碎如无鲜者可用干者二钱代之)
上药六味,先将黄 、石膏、茅根,煎十余沸去渣,澄取清汁二杯,调入甘草、山药末同煎,煎时以箸搅
之,勿令二末沉锅底,一沸其膏即成。再调入蜂蜜,令微似沸,分三次温服下,一日服完,如此服之,久而
自愈。然此乃预防之药,喘嗽未犯时,服之月余,能祓除病根。
肺胞之体,原玲珑通彻者也。为其玲珑通彻,故具 辟之机,而司呼吸之气。其 辟之机无碍,即呼吸之
气自如也。有时肺脏有所损伤,其微丝血管及肺胞涵津液之处,其气化皆湮淤凝滞,致肺失其玲珑之体,即有
碍于 辟之机,呼吸即不能自如矣。然当气候温和时,肺叶舒畅,呼吸虽不能自如,犹不至甚剧。有时薄受风寒,
及令届冱寒之时,肺叶收缩,则瘀者益瘀,能 而不能辟,而喘作矣。肺中之气化,瘀而且喘,痰涎壅滞,而
嗽亦作矣。故用黄 以补肺之阳,山药以滋肺之阴,茅根以通肺之窍,俾肺之阴阳调和,窍络贯通,其
辟之力自适均也。用石膏者,因其凉而能散,其凉也能调黄 之热,其散也能助茅根之通也。用甘草者,因其
味甘,归脾益土,即以生金也。用蜂蜜者,因其甘凉滑润,为清肺润肺,利痰宁嗽之要品也。
茅根禀初春少阳之气,升而能散,原肺脏对宫,肝家之药也。夫肺金主敛,肝木主散,此证因肺金之敛太
过,故用茅根导引肝木之气,入肺以宣散之,俾其 辟之机自若,而喘嗽均不作矣。
或问∶凡药之名膏者,皆用其药之原汁,久经熬炼而成膏。今仅取黄 、石膏、茅根之清汁,而调以山药、
甘草之末与蜜,以成膏者何也?答曰∶古人煎药,皆有火候,及药之宜先入后入,或浸水掺入;及药之宜汤、
宜膏、宜丸、宜散之区别,然今人不讲久矣。如此方黄 、茅根过炼,则宣通之力微,石膏过炼,
则清凉之力减,此三味所以不宜熬膏也。然犹恐药入胃之后,由中焦而直趋下焦,其力不能灌注于肺。故加山
药、蜂蜜之润而粘,甘草之和而缓者,调入成膏。使人服之,能留恋胃中不遽下,俾其由胃输脾,由脾达肺也。
或问∶调之成膏者,恃山药、蜂蜜也。至甘草何不与黄 、石膏同煎取汁,而亦为末调入?答曰∶西人谓,
甘草微有苛(苛即薄荷)辣之味,煎之则甘味减,而苛辣之味转增。是以西人润肺之甘草水,止以开水浸之,
取其味甘、且清轻之气上升也。此方将甘草调入汤中,止煎一沸,亦犹西人作甘草水之意也。
治疗肺脏患有劳损之病,轻微感受风寒就会引发气喘咳嗽,冬季时症状会加重。
生黄芪(四钱) 生石膏(四钱,捣碎成细粉) 净蜂蜜(一两) 粉甘草(二钱,研成细末)
生怀山药(三钱,研成细末) 鲜白茅根(四钱,切碎;如果没有鲜品,可用干品二钱代替)
以上六味药,先将黄芪、石膏、白茅根煎煮十余次沸腾后,滤去药渣,澄清取清汁两杯,调入甘草和山药的细末一同再煎。煎煮时用筷子搅拌,不要让两种粉末沉到锅底,只要再煮沸一次,膏剂就形成了。随后调入蜂蜜,让药液微沸,分三次温服,一天内服完。这样服用,久而久之疾病自然痊愈。然而这是预防性的药物,在气喘咳嗽未发作时,连续服用一个多月,能够清除病根。
肺泡的组织结构,原本就是玲珑剔透、通达透彻的。正因为其玲珑通彻,所以具备开阖(呼吸运动)的机能,从而主管呼吸之气。如果开阖机能没有阻碍,那么呼吸之气就能自如运行。有时肺脏受到损伤,其微丝血管及肺泡涵纳津液之处,气化功能都会淤滞凝塞,导致肺失去其玲珑通透的体质,进而妨碍开阖机能,呼吸就不能自如了。然而在气候温和的时候,肺叶舒展畅达,虽然呼吸不能自如,还不至于非常严重。有时轻微感受风寒,以及到了严寒冰冻之时,肺叶收缩,那么瘀滞的情况会更加严重,只能闭合而不能张开,于是气喘发作。肺中的气化功能,既瘀滞又气喘,痰涎壅盛阻滞,于是咳嗽也发作了。因此使用黄芪来补益肺阳,山药来滋养肺阴,白茅根来疏通肺窍,使肺的阴阳调和,窍络贯通,其开阖的力量自然协调均衡。使用石膏的原因,是因为它性凉而能发散,它的凉性能调节黄芪的热性,它的散性能辅助白茅根的通利作用。使用甘草的原因,是因为它味甘,归入脾经以补益脾胃(土),从而通过“培土生金”的原理来补益肺(金)。使用蜂蜜的原因,是因为它甘凉滑润,是清肺润肺、利痰止嗽的重要药材。
白茅根禀受初春少阳之气,升发且能发散,原本是肺脏对应脏腑(肝)的药物。肺金主收敛,肝木主发散,此证是因为肺金的收敛太过,所以用白茅根引导肝木之气进入肺中宣散,使其开阖机能恢复常态,气喘和咳嗽就不会发作了。
有人问:凡是药名中带“膏”字的,都是用该药的原汁,经过长时间熬炼而成膏。现在只取黄芪、石膏、白茅根的清汁,再调入山药、甘草的粉末与蜂蜜来制成膏,这是什么道理?回答说:古人煎药,都有火候讲究,以及药物适宜先下还是后下,或者浸泡水后掺入;还有药物适宜做汤剂、膏剂、丸剂、散剂的区别,然而今人忽略这些已经很久了。像这个方子,如果黄芪、白茅根过度熬炼,则宣通的力量就会减弱;石膏过度熬炼,则清凉的力量就会减退,这三味药所以不适合熬成膏剂。然而还担心药物进入胃之后,从中焦直接趋向下焦,力量不能灌注于肺。所以加入山药、蜂蜜的滋润粘稠,以及甘草的和缓特性,调入制成膏剂。使人服用后,能在胃中停留而不迅速下行,从而使药力由胃输送到脾,再由脾到达肺。
有人问:调制成膏剂,依靠的是山药和蜂蜜。至于甘草为什么不与黄芪、石膏同煎取汁,而是也作为粉末调入?回答说:西方医学认为,甘草带有轻微的薄荷样辛辣味(苛即指薄荷),如果煎煮,则甜味减少,而辛辣味反而增加。因此西方医生制作润肺用的甘草水,只用开水浸泡,取其味甘,且清轻之气上升的道理。本方将甘草调入汤中,只煮沸一次,也是如同西方人制作甘草水的意思。
To treat **Lao Bing** (Consumptive Disease) of the Lung, where slight exposure to Wind-Cold immediately induces wheezing and coughing, with symptoms worsening in winter.
Sheng Huang Qi (Raw Radix Astragali, 4 qian), Sheng Shi Gao (Raw Gypsum Fibrosum, 4 qian, finely crushed), Jing Feng Mi (Pure Honey, 1 liang), Fen Gan Cao (Powdered Radix Glycyrrhizae, 2 qian, fine powder).
Sheng Huai Shan Yao (Raw Rhizoma Dioscoreae Hypoglaucae, 3 qian, fine powder), Xian Mao Gen (Fresh Rhizoma Imperatae, 4 qian, chopped; if fresh is unavailable, use 2 qian of dried herb as substitute).
Take the above six ingredients. First, decoct Huang Qi, Shi Gao, and Mao Gen for about ten boiling periods, then filter out the dregs. Clarify and obtain two cups of clear liquid. Add the fine powders of Gan Cao and Shan Yao into this liquid and continue decocting. Stir constantly with chopsticks during decoction to prevent the powders from settling at the bottom. Once it boils one more time, the "Gao" (electuary/paste) is formed. Then add the honey, heat until it simmers slightly, and divide into three doses for warm administration, completing the course within one day. With such administration, the disease will heal naturally over time. However, this serves as a preventive medicine. Taking it for over a month when wheezing and coughing have not yet occurred can eradicate the root cause of the disease.
The structure of the **Fei Pao** (Alveoli/Lung Vesicles) is originally delicate, transparent, and unobstructed. Precisely because of this delicacy and transparency, it possesses the mechanism of opening and closing (respiration), thereby governing the breath. If the mechanism of opening and closing is unimpeded, respiration proceeds freely. Occasionally, due to injury to the Lung organ, the microvascular network and the areas within the alveoli that contain body fluids suffer from stagnation and obstruction of Qi transformation. This causes the Lung to lose its delicate and transparent constitution, thereby hindering the opening-and-closing mechanism, making respiration difficult. However, during mild weather, the lung lobes are relaxed and comfortable; although respiration is not entirely free, it is not severe. When exposed to slight Wind-Cold, or during freezing cold seasons, the lung lobes contract. Consequently, the existing stasis worsens. The lungs become capable of closing but unable to open, resulting in wheezing. In the lungs, Qi transformation is stagnant accompanied by wheezing, and phlegm-saliva accumulates and obstructs, leading to coughing. Therefore, Huang Qi is used to tonify Lung Yang, Shan Yao to nourish Lung Yin, and Mao Gen to unblock Lung orifices. This harmonizes the Yin and Yang of the Lung and connects the orifices and collaterals, so that the power of opening and closing becomes balanced. Shi Gao is used because it is cool and dispersing; its coolness regulates the heat of Huang Qi, and its dispersing action assists the unblocking effect of Mao Gen. Gan Cao is used because its sweet flavor enters the Spleen to benefit Earth (Spleen), thereby generating Metal (Lung) via the principle of "Earth generating Metal." Honey is used because it is sweet, cool, slippery, and moistening, serving as a key herb for clearing and moistening the Lung, promoting expectoration, and calming cough.
Mao Gen inherits the Qi of Shaoyang (Lesser Yang) in early spring; it ascends and disperses. It is originally an herb associated with the Liver, which corresponds to the Lung. Metal of the Lung governs convergence/astringency, while Wood of the Liver governs dispersion. In this condition, the converging nature of Lung Metal is excessive. Thus, Mao Gen is used to guide the Qi of Liver Wood into the Lung to disperse it, restoring the normal mechanism of opening and closing, so that wheezing and coughing cease.
A question arises: All medicines named "Gao" (electuary) are made from the pure juice of the herbs, boiled for a long time until thickened. Why does this formula only take the clear juice of Huang Qi, Shi Gao, and Mao Gen, and mix them with powders of Shan Yao, Gan Cao, and honey to form the electuary? The answer is: Ancient practitioners paid great attention to fire control, the order of adding herbs (whether to add first or later), soaking methods, and the distinctions between decoctions, electuaries, pills, and powders. However, modern people have neglected these details for a long time. In this formula, if Huang Qi and Mao Gen are over-boiled, their dispersing and unblocking power diminishes; if Shi Gao is over-boiled, its cooling power decreases. Hence, these three herbs are unsuitable for being boiled down into a thick electuary. Nevertheless, there is a concern that after entering the stomach, the medicinal force might pass directly from the Middle Jiao to the Lower Jiao without reaching the Lung. Therefore, the moist and sticky properties of Shan Yao and honey, along with the harmonizing and moderating nature of Gan Cao, are added to form the electuary. This ensures that upon ingestion, the medicine lingers in the stomach rather than descending rapidly, allowing its effects to transmit from the Stomach to the Spleen, and from the Spleen to the Lung.
Another question: The formation of the electuary relies on Shan Yao and honey. Why is Gan Cao not decocted together with Huang Qi and Shi Gao to extract the juice, but instead added as a powder? The answer is: Western medicine notes that Gan Cao has a slight peppermint-like pungent/spicy taste. Decoction reduces its sweetness and increases this pungent quality. Therefore, Western physicians prepare Gan Cao water for moistening the lungs by simply steeping it in hot water, aiming to preserve its sweet flavor and allow its light, ascending Qi to rise. In this formula, Gan Cao is added to the decoction and boiled only once, following the same rationale as the Western method of preparing Gan Cao water.
