此治肺治脾之药，合而用之，咳嗽之病、吐泻之症各愈，所谓一方而两用之也。
气虚和气实，不可不加以平调。所谓气实，并非真正的气实，而是正气虚弱而邪气盛实。治疗方法应当使用补益正气的药物，方剂为：人参（一钱）、白术（一钱）、甘草（一钱）、麻黄（一钱）、半夏（一钱）、柴胡（三钱）、白芍（三钱），水煎服。
推广开来，治疗气病并非只有一种方法：如果是气陷（中气下陷），可以使用补中益气汤；如果是气衰（元气不足），可以采用六君子汤；如果是气寒，则用人参、白术等药独用……总之，气虚表现为身体羸弱，气实则表现为形体壮盛。虚证使用上述前方；实证使用另一方，即：枳壳（五分）、白术（一钱）、陈皮（五分）、茯苓（三钱）、白芍（二钱）、山楂（十个）、柴胡（一钱）、栀子（一钱）、甘草（一钱），水煎服。
血液不能循行于经脉之中，或向上溢出，或向下流出，或从四肢毛孔各处出血。血液在经络中运行，向外布散于皮毛，向内滋养脏腑，若在内运行失常，导致妄行，则出现大小便出血等症状。方剂为：当归（三钱）、白芍（三钱）、麦冬（三钱）、熟地黄（五钱）、生地黄（五钱）、茜草根（一钱）……此方即在四物汤基础上加减而成，妙处在于使用茜草根，以引导血液回归经脉。服用一二剂后，再服用六味地黄汤，通过补肾来滋养肝木。
六味地黄汤组成：熟地黄（五钱）、山茱萸（五钱）、山药（二钱）、牡丹皮（二钱）、泽泻（二钱）、北五味子（一钱）。血症最适宜使用此方，长期服用三年可不再吐血。
如果人咳嗽不止、呕吐腹泻不止，这是肺和脾受到了损伤。人们通常认为：咳嗽应该治肺，呕吐腹泻应该治脾。殊不知，咳嗽与吐泻往往相互关联，上部的症状可能源于下部……方剂为：人参（一钱）、麦冬（二钱）、茯苓（二钱）、柴胡（一钱）、车前子（一钱）、神曲（五分）、薏苡仁……这是治疗肺和脾的药物，合并使用，可以使咳嗽的病、呕吐腹泻的症状各自痊愈，这就叫作一方两用。
Deficiency and excess of Qi must be balanced. What is termed "Qi Excess" is not true excess, but rather a deficiency of Righteous Qi (Zheng Qi) accompanied by an abundance of Pathogenic Qi (Xie Qi). The treatment method should employ herbs that tonify the Righteous Qi: Ren Shen (Ginseng Radix et Rhizoma, 1 qian), Bai Zhu (Atractylodis Macrocephalae Rhizoma, 1 qian), Gan Cao (Licorice Root, 1 qian), Ma Huang (Ephedrae Herba, 1 qian), Ban Xia (Pinelliae Tuber, 1 qian), Chai Hu (Bupleuri Radix, 3 qian), Bai Shao (Paeoniae Radix Alba, 3 qian). Decoct in water and take orally.
Extending this principle, treating Qi disorders is not limited to a single approach: For Qi Sinking (prolapse of middle Qi), Bu Zhong Yi Qi Tang may be used; for Qi Decline (deficiency of primal Qi), Liu Jun Zi Tang can be selected; for Cold Qi, Ren Shen and Bai Zhu are used exclusively... In summary, Qi deficiency manifests as emaciation and weakness, while Qi excess manifests as robustness and strength. For deficiency syndromes, use the aforementioned formula; for excess syndromes, use another formula: Zhi Ke (Aurantii Fructus, 0.5 qian), Bai Zhu (1 qian), Chen Pi (Citri Reticulatae Pericarpium, 0.5 qian), Fu Ling (Poria, 3 qian), Bai Shao (2 qian), Shan Zha (Crataegi Fructus, 10 pieces), Chai Hu (1 qian), Zhi Zi (Gardeniae Fructus, 1 qian), Gan Cao (1 qian). Decoct in water and take orally.
When Blood fails to remain within the vessels, it may bleed upwards, downwards, or from various pores on the limbs. Blood circulates through the meridians, distributing externally to the skin and hair, and internally nourishing the Zang-Fu organs. If internal circulation becomes disordered, leading to reckless bleeding, symptoms such as hematochezia or hematuria may occur. The formula consists of: Dang Gui (Angelicae Sinensis Radix, 3 qian), Bai Shao (3 qian), Mai Dong (Ophiopogonis Tuber, 3 qian), Shu Di Huang (Rehmanniae Radix Praeparata, 5 qian), Sheng Di Huang (Rehmanniae Radix, 5 qian), Qian Cao Gen (Rubiae Cordifoliae Radix et Rhizoma, 1 qian)... This formula is a modification of Si Wu Tang (Four Substances Decoction), with the brilliance lying in the use of Qian Cao Gen to guide Blood back into the vessels. After taking one or two doses, administer Liu Wei Di Huang Tang (Six-Ingredient Pill with Rehmannia) to tonify the Kidney to nourish Liver Wood.
Liu Wei Di Huang Tang composition: Shu Di Huang (5 qian), Shan Yu Rou (Corni Fructus, 5 qian), Shan Yao (Dioscoreae Rhizoma, 2 qian), Dan Pi (Moutan Cortex, 2 qian), Ze Xie (Alismatis Rhizoma, 2 qian), Bei Wu Wei Zi (Schisandrae Chinensis Fructus, 1 qian). This formula is most suitable for blood disorders; long-term use for three years can prevent hemoptysis.
If a person suffers from incessant coughing and incessant vomiting and diarrhea, this indicates injury to the Lung and Spleen. People generally believe that coughing should be treated by addressing the Lung, and vomiting/diarrhea by addressing the Spleen. However, they fail to realize that these conditions are interconnected... The formula includes: Ren Shen (1 qian), Mai Dong (2 qian), Fu Ling (2 qian), Chai Hu (1 qian), Che Qian Zi (Plantaginis Semen, 1 qian), Shen Qu (Massa Medicata Fermentata, 0.5 qian), Yi Yi Ren (Coicis Semen, ...). These are herbs for treating the Lung and Spleen; when combined, they can cure both the cough and the vomiting/diarrhea simultaneously. This is referred to as "one formula serving two purposes."
