Treatise on Febrile Diseases and Synopsis of the Golden Chamber = "Treatise on Febrile Diseases and Miscellaneous Diseases"
Treatise on Febrile Diseases and Synopsis of the Golden Chamber are two books separated from one. The Golden Chamber Essentials contains prescriptions for using astragalus. Huangqi Guizhi Wuwu Decoction is used to treat yellow sweat, Fangji Huangqi Decoction is used to treat Feng Shui, and Huangqi Jianzhong Decoction is used to treat fatigue and tenesmus.
So, why is it that after the Song Dynasty divided the Treatise on Febrile Diseases into Treatise on Febrile Diseases and Synopsis of the Golden Chamber, there were no prescriptions using astragalus in Treatise on Febrile Diseases? Personally, I think it may have something to do with the positioning of the book. Treatise on Febrile Diseases is more focused on treating external diseases, while Theory of the Golden Chamber is more focused on treating internal injuries and miscellaneous diseases.
When treating exogenous diseases, many Chinese medicine practitioners do not like to use astragalus for fear of astringing evil spirits. Perhaps for this reason, there are no prescriptions using astragalus in Treatise on Febrile Diseases. In fact, astragalus is also included in Zaizao Powder in the traditional Chinese medicine prescription book. In other words, it is not impossible to use astragalus when you have external symptoms. However, you must pay attention to the rise and fall of the qi machine, so that the evil energy cannot have no outlet.
Of course, if there is no Qi-dispersing medicine, it is indeed not suitable to use astragalus alone when you have external symptoms.
