Fable
Why the same medicine is different every time
The clinic in Bluestone Town was originally very small. The old doctor treated patients, the apprentice filled prescriptions, and paper labels were pasted on the medicine drawers, so everyone knew what went in which compartment. When there were few patients, this method was very stable.
Later the town opened a night market, more outsiders came, and illnesses became more varied. The apprentices began keeping their own notebooks: some recorded medicinal properties by season, some recorded dosages by patient age, and some changed formulas based on what the shopkeeper said verbally.
The first problem arose when the same patient received medicine that tasted different in the morning and in the evening. Both apprentices said they had followed the rules, but the rules they used were not the same book.
The shopkeeper's naive fix was to have everyone copy the booklet more neatly. Soon the counter was piled with tidy notebooks, yet dispensing medicine was still unreliable, because no single notebook was the authoritative one.
What was more troublesome was that daytime decoction used one set of records, while nighttime emergency care used another quick-reference table. Ratios found effective during the day might not be available at night; contraindications discovered at night were unknown during the day.
A young pharmacist stopped dispensing and first took stock of all the common judgments in the shop: season, patient age, allergies, past illnesses, follow-up results, herb batches. He unified them into items the pharmacy recognized.
He also set aside two cabinets: one holding slowly organized complete records, for review and revision; the other holding the latest, fastest-to-retrieve key points, for immediate use at the counter. Every record had a source, an update time, and applicable boundaries.
Afterward, the apprentices no longer each invented their own formulas. New prescriptions had to be registered and verified before entering the counter quick-reference; expired old prescriptions were also marked. The clinic finally enabled the same trusted judgment to be used day and night. The manager also required every key point to be traceable back to the original record. If a dosage came from an old patient three years ago, the counter had to know whether it still applied; if a new contraindication was discovered at night, the slow counter the next day also had to see it. Unification was not piling all the notebooks together, but keeping the same judgment consistent across different scenarios. Later, when the clinic expanded to a neighboring town, the manager did not allow branches to each write their own booklet. Connect these two counters first, then open the clinic; otherwise, the larger the scale, the more chaotic the medicine. Later, during the review, everyone wrote this lesson into daily rules: first see where on site actually changed the result, then decide what to keep, repair or restrict.
