○燥可去湿
琼玉膏的组成药物包括生地黄。将人参、茯苓与白蜜共同熬炼成膏剂服用。对于肺阴枯竭引起的干咳及虚劳病症，此方通过金（肺）水（肾）相互滋生的原理，疗效显著加倍。（取鲜生地四斤，榨取汁液一斤；加入白蜜二斤，煮沸后用绢布过滤。将茯苓十二两、人参三两分别研磨成粉末，倒入前述药汁中搅拌均匀。装入瓷瓶，用十余层纸覆盖瓶口，再加箬叶密封瓶口。放入沙锅中，用长流水淹没瓶颈，以桑木柴火煎煮三天三夜。取出后，用绢纸扎紧瓶口，再用蜡封固，悬挂于井中一日。取出后再煎煮半个时辰。用药汤调服。）
陈修园说：人参味甘性寒，质地柔润，能补助肺气。然而肺本恶寒，凡是咳嗽多属于形体受寒或饮食生冷所致，若使用这种寒凉滋润滋补的药物，必然会加重咳嗽。以前的医生误认为人参具有温散寒邪的性质，所以有“肺热还伤肺”的说法。他们不知道肺合皮毛，凡是咳嗽由风寒外袭引起，应当使用干姜、五味子、细辛等药物加减治疗，忌用人参的寒性。但是，肺是脏腑的华盖（保护伞），如果脏腑之火得不到水的制约，会上刑克肺金，导致肺燥干咳，表现为有声无痰，这与寒饮引起的咳嗽不同。这种情况正适宜用人参的润性来滋养燥邪，用人参的寒性来制约热邪，这就是琼玉膏之所以神效无比的原因。以前的医生凡是使用清燥的方剂，必定会用人参，可知其擅长滋养津液。
（主治热邪损伤元气，气短倦怠，口干出汗。）
生脉散由麦冬、五味子与人参配合施用。暑热之邪刑克肺金，导致脉搏虚弱难以支撑。如果误认脉虚而通用此方，那造成医疗事故的责任在于谁呢？（人参五分，麦冬八分，五味子九分，水煎服。）
陈修园说：脉象，根源始于肾，化生于胃，汇聚于肺。张仲景在手足冰冷、脉微欲绝的病症中，选用通脉四逆汤，以扶持少阴的真阳；在心下悸动、脉结代的病症中，选用复脉汤，以滋养阳明经的津液，这些都是挽救危局的方剂。孙思邈制定生脉散，是针对暑热损伤肺脏，肺脏受损则脉搏逐渐虚弱散乱，令人担忧。应当在未受损伤之前，取人参、麦冬的甘润，以及五味子的酸敛，在无病之时预先服用以保养身体。除了暑月之外，不可以将此作为常规示例。现在的人被“生脉”这个名字所迷惑，凡是遇到脉绝的危重证候，每每投用此方，病人立即死亡，这也是孙思邈命名不当留下的祸患。另一版本作“参麦散”，较为妥当。
○燥性药物可以去除湿气
The ingredients of Qiongyu Gao (Jade Dew Paste) include Shengdihuang (Rehmanniae Radix). It is prepared by refining Ginseng, Poria, and White Honey into a paste for consumption. For conditions of Lung Yin exhaustion manifesting as dry cough and consumptive disease, this formula yields double the efficacy through the mutual nourishment of Metal (Lung) and Water (Kidney). (Take four jin of fresh Shengdihuang [Rehmanniae Radix], extract one jin of juice. Boil with two jin of White Honey, filter through silk cloth. Grind twelve liang of Fuling [Poria] and three liang of Renshen [Ginseng] into powder. Mix evenly with the aforementioned juice. Place in a porcelain jar, cover the mouth with more than ten layers of paper, seal with bamboo leaves. Put in a clay pot, submerge the neck in running water, and boil over mulberry wood fire for three days and nights. Remove, tie the mouth with silk paper, seal with wax, and suspend in a well for one day. Take out and boil again for half a day. Administer mixed with decoction.)
Chen Xiuyuan stated: Renshen [Ginseng] is sweet and cold in nature, soft and moist, and supplements Lung Qi. However, the Lung dislikes cold; most coughs are caused by external cold or drinking cold fluids. Using such cold, moist, and tonifying medicines will inevitably increase coughing. Past physicians mistakenly believed Renshen had warming properties to dispel cold, hence the saying "Lung heat further injures the Lung." They did not realize that the Lung governs the skin and hair; coughs arising from external Wind-Cold should be treated with modifications of Ganjiang [Dried Ginger], Wuweizi [Schisandrae Fructus], and Xixin [Asari Radix], avoiding the cold nature of Renshen. Nevertheless, the Lung is the canopy of the viscera. If the Fire of the viscera is not controlled by Water, it scorches Lung Metal, causing Lung dryness and dry cough with sound but no phlegm, which differs from cough due to cold-fluid retention. In such cases, it is precisely appropriate to use the moistening property of Renshen to nourish dryness and its cold nature to restrain heat. This is why Qiongyu Gao is extraordinarily effective. Past physicians always included Renshen in formulas for clearing dryness, indicating its strength in nourishing body fluids.
(Treats Heat damaging Yuan Qi, resulting in shortness of breath, fatigue, dry mouth, and sweating.)
Shengmai San (Pulse-Generating Powder) consists of Maidong [Ophiopogonis Radix], Wuweizi [Schisandrae Fructus], and Renshen [Ginseng]. Summer-Heat scorching Lung Metal causes the pulse to become weak and unsupported. If one mistakes this pulse deficiency for a general indication and universally applies this formula, who bears the blame for this surgical error? (Renshen [Ginseng] 5 fen, Maidong [Ophiopogonis Radix] 8 fen, Wuweizi [Schisandrae Fructus] 9 fen, decocted in water and taken orally.)
Chen Xiuyuan stated: The pulse originates in the Kidney, is generated by the Stomach, and converges in the Lung. Zhang Zhongjing, in cases of cold extremities and a faint pulse nearly imperceptible, selected Tongmai Sini Tang (Cinnamon Twig and Prepared Aconite Decoction to Restore the Pulse) to support the True Yang of Shaoyin. In cases of palpitations and intermittent pulse, he selected Fumai Tang (Restore the Pulse Decoction) to nourish the body fluids of Yangming. Both are critical rescue formulas. Sun Simiao formulated Shengmai San (Pulse-Generating Powder) for Summer-Heat injuring the Lung; when the Lung is injured, the pulse gradually becomes weak and scattered, which is worrying. One should take the sweet and moist properties of Renshen [Ginseng] and Maidong [Ophiopogonis Radix], along with the sour and astringent properties of Wuweizi [Schisandrae Fructus], prior to injury, taking them preventively when healthy. Except during the summer months, this should not be used as a routine example. Today, people are confused by the name "Shengmai" (Generate Pulse); whenever they encounter a condition of pulse cessation, they administer this formula, leading to immediate death. This is the disaster caused by Sun Simiao's improper naming. Another version calls it Shenmai San (Ginseng and Ophiopogon Powder), which is more appropriate.
