Chai Hu (Radix Bupleuri), Qian Hu (Radix Peucedani), Wu Mei (Fructus Mume), Hu Huang Lian (Rhizoma Coptidis, specifically *Coptis chinensis* var. *angustata*, often referred to as Hualian in this context but here specified as Hu Huang Lian which usually points to *Picrorhiza rhizome* or similar bitter-cold herbs for bone-steaming; however, standard TCM herb for "Hu Huang Lian" is *Picrorhizae Rhizoma* / Kutki. Note: The text says "Hu Huang Lian", WHO term is *Picrorhizae Rhizoma*).

For cases of Feng Lao Gu Zheng (Bone-steaming due to wind-induced consumptive disease) that persist without recovery, accompanied by coughing, hemoptysis, night sweats, and spermatorrhea, with a wiry and rapid pulse, this formula is indicated.

This formula treats consumptive disease caused by wind. Wind is the chief of all diseases; it is the yang qi of heaven, governing the dispersal and excretion of all things. Thus, when at the exterior, it causes sweating; when in the Lung, it causes coughing; when in the Liver, it causes hemoptysis; when in the Kidney, it causes spermatorrhea; and when adhering to the bones, it causes steaming heat and night sweats. This theory contains its subtleties in the *Ling Shu*. From the Han and Tang dynasties through the Song and Yuan dynasties, various physicians had not fully expounded upon this theory. No wonder it is difficult for practitioners to cure patients with Lao Zhai (consumptive tuberculosis). Chai Hu resolves wind that is neither strictly at the exterior nor the interior. Hu Huang Lian (*Picrorhizae Rhizoma*) clears heat that has penetrated into the muscles and adhered to the bones. Qian Hu addresses pathogenic factors in the exterior and interior of the Spleen and Lung. Chu Cheng stated: "Sour flavors enter the bones." Therefore, the use of Wu Mei can also serve to consolidate and stop bone-steaming. Zhu Yang Yin (Porcine Gallbladder) nourishes yin; Zhu Sui nourishes the bones; Tong Bian assists in extinguishing fire. Jiu Bai is acrid and hot. Used in small amounts, it acts as a guiding drug. The Classics state: "In severe cases, follow the condition." This refers to such situations.

Qin Jiao (Radix Gentianae Macrophyllae), Zhi Mu (Rhizoma Anemarrhenae), Dang Gui (Radix Angelicae Sinensis) [each half liang], Bie Jia (Carapax et Plastrum Testudinis) [1 liang], Wu Mei [one piece], Qing Hao (Herba Artemisiae Annuae) [five leaves], Chai Hu, Di Gu Pi (Cortex Lycii) [each 1 liang].

For cases of Feng Lao Gu Zheng with high fever and emaciation of muscles, this formula is indicated.

Wind is yang qi. Therefore, when at the exterior, it causes exterior heat; when in the interior, it causes interior heat; when adhering to the bones, it causes bone-steaming high fever; and prolonged steaming leads to muscle emaciation. Without wind, there is no bone-steaming; this is Kun's proposition. Luo Qianfu advocated this formula, presumably due to a profound spiritual契合 (resonance/fit). Chai Hu and Qin Jiao are wind-dispelling drugs capable of driving out wind from muscles and bones. Di Gu Pi and Zhi Mu are cold-natured substances capable of treating heat in muscles and bones. Turtle belongs to the yin category; its shell belongs to the bone category. Treating bone with bone makes it a guide for other herbs. Nourishing yin with yin substances helps to retreat bone-steaming in the yin aspect. Wu Mei is sour in flavor, capable of guiding other herbs into the bones to consolidate and clear their heat. Qing Hao is bitter and acrid, capable of entering the muscles along with other herbs to resolve steaming heat. Additionally, Dang Gui nourishes blood and guides other herbs into the blood to eliminate heat within the yin.
