"Left Imperial Physician, why are you so certain there was something wrong with the patient's food?" Gu Zhaoyan asked.
"I once encountered a similar case. We checked everything that had been consumed, but we simply couldn't find the source of the problem. It wasn't until the patient’s family casually mentioned that the patient was particularly fond of pickled vegetables—especially those made from radishes—that I realized something. Radishes have a carminative effect, but they should not be consumed before taking medicinal decoctions, or the efficacy of the medicine will be lost. Later, the patient abstained from eating them, and within a few days, they recovered."
