Knowing the formulas is one thing. Knowing which one belongs to the patient in front of you is another.
The old Japanese pharmacy in this image is full of drawers, bottles, containers, and possibilities. I like it because it captures something that is easy to forget when we study Kampo: having many formulas available does not make the clinical decision easier.
Tōdō pushed attention away from simply building a theoretical explanation and then choosing a prescription that seemed to fit. He was much more interested in the relationship between the formula and the actual presentation in front of him—the shō 證.
That does not mean “one symptom = one formula.” Quite the opposite. The same complaint could lead to very different choices depending on the rest of the picture: strength or weakness, tension or softness, appetite, stool, temperature, abdominal findings, and the way the illness was actually showing itself.
I think this is one of the places where Kampo can be misunderstood. A formula is not just something attached to a diagnosis or a symptom name. It has to fit the patient.
The more I worked on Yoshimasu Tōdō: The Physician Who Changed Kampo Medicine Forever, the more I realized that this way of thinking was one of the most important things he left behind.
For practitioners here: what do you think gets lost when shō is reduced to a checklist?
