[Contraindications] Chen Shigong stated: In cases of Yin deficiency with fire hyperactivity, and impotence caused by loss of will, leading to closed and dense fire qi that cannot diffuse and emerge, [it is contraindicated]. Also for Benglou due to...

I modified Qianghuo Shengshi Tang (Notopterygium Decoction to Overcome Dampness) and assisted it with Cizhu Wan (Magnetite and Cinnabar Pill). He was cured in two months. This transforms stagnation and brings out...
Ao's Commentary: Huangpo (Yellow Matriarch) refers to the Spleen. Ying'er (Infant) refers to the Kidney. Nu (Female) refers to the Heart. The term "Huangpo matches the Infant" implies regulating Spleen Qi to facilitate the interaction between Heart and Kidney.
