It is said that cold exposure is the most taboo for heatstroke. Then why are Laifu Dan (Recovery Pill), Huanglong Wan (Yellow Dragon Pill) taken with garlic and water? This is because the medicinal properties of these drugs are warm, used for conditions triggered by cold pathogens. This aligns with Lu Zuchang's correction of errors. It is recorded that Li Zhaowen suffered from a thirst disease. Lu Zuchang diagnosed him and asked, "Did you contract this illness in the evening during the summer month?" Li replied, "Yes." Lu boiled Ginseng Decoction (Renshen Tang), waited for it to cool, and had the patient swallow Yuhu Wan (Jade Pot Pill), after which he recovered.
