治瘴毒。阴虚发热。烦躁手足冷。鼻尖凉。身体重。舌苔黑。引饮烦渴。自利呕逆。汗出恶风。
大附子（一个，去皮脐分作四服） 干姜（二钱炮）
上水煎。欲饮水者。冷服之。瘴病烦渴引饮。
舌黑阳气上浮。心肺极热也。手足冷。鼻尖凉。吐利脾土无阳。虚寒也。身体重。寒气外盛也。汗出
恶风。阳气外泄。不能卫皮毛也。姜附之辛热能温中祛外寒。而收外泄之阳气。冷冻饮料之以导心肺之
热下行。而暖下焦上焦之热下行。中下二焦温暖。则寒热退。诸病息矣。
治瘴病上热下寒。腿足寒厥。
大附子（五钱） 沉香（磨浓汁）
上姜七片煎。八分乘热入沉香汁。勿令十分热。放冷服之。
此药既主上热下寒。须真正沉香方佳。虽弄沉亦不济事。况此香自有数种。既用服饵当以滋味别之。
如咀嚼而香甜者。性平辛辣者。性热用者。须审择以对证。附子率用小者。及漏芦侧子之类。谓难得
大者。然阴毒及冷瘴。但欲一时壮阳气可也。若虚而藉降气敛阳。倘非地道大附子。非徒药之无益。
夫亦处方者之罪也。瘴病本上热下寒。加之腿足寒厥。乃下焦肾经阳气尽浮于上。肾经空虚之极。
是方用附子。乃肾经本药。加以沉香能引上焦阳气上肾。肾中有阳气则下元暖。根本固而邪气自息矣。
To treat miasma toxin (Zhang Du). Yin deficiency with fever, irritability, cold hands and feet, cool nasal tip, heavy body, black tongue coating, excessive thirst with drinking, spontaneous diarrhea, vomiting and regurgitation, sweating with aversion to wind.
Da Fuzi (one piece, peeled and core removed, divided into four doses) Ganjiang (2 qian, processed by stir-frying)
Decoct with water. For those desiring to drink water, take it cold. Miasma disease with irritability, excessive thirst and drinking.
Black tongue coating indicates floating-up of Yang Qi, extreme heat in the Heart and Lung. Cold hands and feet, cool nasal tip indicate lack of Yang in Spleen Earth, deficiency-cold. Heavy body indicates excess external Cold Qi. Sweating with aversion to wind indicates leakage of Yang Qi externally, inability to protect the skin and hair. The pungent and hot nature of Jiang (Ginger) and Fu (Aconite) can warm the middle and dispel external cold, thereby recovering the leaking Yang Qi. Cold beverages guide the heat of the Heart and Lung downward, while warming the Lower Jiao and guiding the heat of the Upper Jiao downward. When the Middle and Lower Jiao are warm, then cold and heat recede, and all diseases cease.
To treat miasma disease with upper heat and lower cold, cold reversal in legs and feet.
Da Fuzi (5 qian) Chenxiang (ground into thick juice)
Decoct with seven slices of Ginger. Add eight-tenths of the Chenxiang juice while hot. Do not let it become extremely hot. Let it cool before taking.
This medicine primarily addresses upper heat and lower cold; only genuine Chenxiang is excellent. Even if mixed with other woods, it is useless. Moreover, this fragrance has several types. When used for ingestion, one must distinguish them by taste. Those that are sweet and fragrant when chewed have a neutral nature; those that are pungent and spicy have a hot nature. One must carefully select according to the syndrome. Fuzi usually uses smaller pieces, such as Loulu and Cizi, claiming large ones are hard to obtain. However, for Yin toxicity and cold miasma, merely wishing to boost Yang Qi at once is sufficient. If deficiency requires descending Qi and gathering Yang, unless it is authentic Da Fuzi from proper regions, not only will the medicine be ineffective, but it will also be the fault of the prescriber. Miasma disease inherently involves upper heat and lower cold, compounded by cold reversal in legs and feet, meaning Yang Qi of the Kidney Meridian in the Lower Jiao floats entirely upward, leaving the Kidney Meridian extremely empty. This formula uses Fuzi, which is the primary herb for the Kidney Meridian, combined with Chenxiang which can guide Yang Qi from the Upper Jiao down to the Kidney. When Yang Qi exists in the Kidney, the lower origin becomes warm, the root is solidified, and pathogenic factors naturally cease.
