ABSTRACT
We investigated the history and indications of Toenho, Kinseiho, and Cho-Sanshaku-Shinteiho, which are different formulae with the same name of seishoekkito. According to the description in “Futsugoyakushitsuhokankuketsu” written by Sohaku Asada, Kinseiho exhibits an immediate effect, while Toenho has preventive effects. However, according to the original text, Kinseiho was formulated such that it could be administered regularly in the summer for prophylaxis. Furthermore, Kinseiho is regarded as a simplified formula with the central structure of Toenho. This implies that Kinseiho is composed of selected crude drugs used in Toenho that are responsible for the main effects of Toenho, such as invigorating spleen energy, clearing fever and generating body fluids. Moreover, there is an instruction to arrange Kinseiho to fit each patient’s condition. In this study, it was found that Cho-Sanshaku-Shinteiho described in “Futsugoyakushitsuhokankuketsu” is a modification of Kinseiho prescribed by Katsuki Gyuzan for patients with fever, consistent with the concept of personalized medicine. The medical extract preparation seishoekkito, which is currently widely used, is Kinseiho. We may use it with heat-clearing formula, fluid-regulating formula or some modifications to make the appropriate formulation based on the patient's symptoms.
