Bai Shao (Radix Paeoniae Alba) [1.5 qian, stir-fried with wine], Ren Shen (Radix Ginseng), Chen Pi (Pericarpium Citri Reticulatae), Huang Qi (Radix Astragali) [honey-roasted], Dang Gui (Radix Angelicae Sinensis) [stir-fried with wine], Bai Zhu (Rhizoma Atractylodis Macrocephalae) [soil-stir-fried], Gan Cao (Radix Glycyrrhizae) [roasted], Gui Xin (Cortex Cinnamomi) [each 1 qian], Shu Di Huang (Radix Rehmanniae Preparata) [stir-fried with ginger juice], Fu Ling (Poria) [each 0.75 qian], Wu Wei Zi (Fructus Schisandrae) [stir-fried and pounded], Yuan Zhi (Radix Polygalae) [woody core removed, each 0.5 qian].

From the spring season when all things flourish, to the autumn of desolation when all things wither, the Spleen belongs to Kun Earth, and the Lung belongs to Qian Metal. The *Classic* states: "The Spleen Qi scatters essence and transports it upward to the Lung; this is the rising of Earth Qi." The Lung governs regulation and unblocks the water passages, transporting downward to the Bladder; this is the descending of Heaven Qi. In hexagram imagery, this corresponds to Tai (Peace). If Spleen and Lung Qi are deficient, the upper and lower do not interact, and Yin and Yang are blocked. Thus, one presents with a sallow complexion and emaciation, similar to withered plants. Ren Shen and Wu Wei Zi warm the Lung; Bai Zhu, Gan Cao, and Fu Ling warm the Spleen; Chen Pi and Bai Shao warm the Liver; Di Huang and Gui Xin warm the Kidney; Dang Gui and Yuan Zhi warm the Heart. The five Zang organs irrigate each other, generating Qi and Blood within the organs, making it difficult for pathogenic factors to hide within them. "Warming" refers to the energy of spring sunshine. With the spring energy causing flourishing, can there be any part of the body that does not thrive? Hence, it is called the Ying Yang Tang (Nourishing Decoction). Xue Lizhai stated: "When Qi and Blood are deficient and manifest various symptoms that are indescribable, regardless of the disease or pulse, simply using this decoction will cause all symptoms to recede. This demonstrates the insight capable of restoring life."

A simple method for treating Lao Disease (consumptive tuberculosis): Select a Gui Hai day, after the second watch, when the Six Spirits gather. Remove lower garments, stand upright, and mark the depressions on both sides of the waist with ink; these are called Yao Yan acupoints (Waist Eye points). Then lie prone on the bed. Moxa-burn each point seven moxa cones (Zhuang). The "Lao worms" may be expelled through vomiting or diarrhea. Collect them and burn them with fire; discard them in rivers to prevent harm to others. After moxibustion, it is advisable to take Jiang Jun Wan (General Pill).
