Guizhi Gancao Longgu Muli Tang
Used to treat palpitations and irritability caused by heart yang deficiency,
based on Guizhi Gancao Tang to gently warm and tonify heart yang, with Longgu and Muli to quietly calm the spirit.
[[Fengyin Tang]]
Clears heat, extinguishes wind, and calms internally; mainly used for wind-induced convulsions (acute cerebrovascular disease).
Guizhi Gancao Longgu Muli Tang plus six kinds of mineral medicines (Hanshuishi, Huashi, Chishizhi, Baishizhi, Zishiying, Shigao), Dahuang, and Ganjiang.
- The main herbs are Shigao and Dahuang; Shigao clears heat and calms, Dahuang is bitter and cold with a downward action; together they facilitate the lowering of qi mechanism.
- Ganjiang and Guizhi prevent damage to yang by cold and cool herbs, especially heart and spleen yang; fresh ginger protects spleen yang, Guizhi protects heart yang.
- Hanshuishi and Huashi promote diuresis, reducing circulation and lowering blood pressure.
- Muli and Zishiying strengthen heavy calming; Shizhi and Longgu astringe and prevent excessive diarrhea.
[[Jianling Tang]]
Raw Huai Shan Yao, Huai Niuxi, Raw Dai Zeshi, Raw Longgu, Raw Muli, Raw Huai Dihuang, Raw Hang Shao, Baiziren, rust residue concentrated water for decoction.
Based on the idea of Fengyin Tang, placing emphasis on Zeshi, Longgu, and Muli for sedimentation and descent to guide blood downward.
From Jinkui there is Fengyin Tang, which dispels hot convulsions. Convulsions are named due to heat, clarifying that heat is the cause. The symptoms resemble cerebral congestion. The formula uses six mineral medicines, mostly cold in nature. Although there is spicy-warm Ganjiang and Guizhi, combined with Dahuang, Shigao, Hanshuishi, and Huashi, the overall property is still cold (careful examination shows that Guizhi and Ganjiang should not be used). All mineral properties are descending, especially Dahuang, which strongly descends and can induce the reversal of the upward flowing blood to descend. Also Longgu, Muli, and Zishiying are used together to firmly restrain the rising qi; used with Guizhi they help pacify liver qi. When the rising liver qi does not injure the upper body, the excessively congested blood can gradually descend. Although named Fengyin, the formula never uses wind-dispelling herbs; thus it clearly treats hot convulsions rather than stroke. Later generations misunderstood the idea of this formula and many misinterpret it. The rough draft Jianling Tang heavily uses Zeshi, Longgu, and Muli, and sometimes adds Shigao. This is secretly based on the meaning of Fengyin Tang (the text after Fengyin Tang in the formula is very brief and seems not to be from Zhang Zhongjing’s writing, so many doubt that those herbs were added later; thus the herbs in the formula are not pure).
