One Should Stay Away from the Heat

"What should I do?" the patient asked.

"I think you should stop taking the cold medicine," Wang Yao replied. "I'll prescribe you something else."

He thought for a moment before prescribing a formula that could stop diarrhea and drive away the cold.

"I need to stop your diarrhea before treating your cold. Otherwise, neither of your problems will be fixed," Wang Yao said.

"OK, thank you," the patient said.

Half of the patients coming to the clinic during the day had problems with their stomachs. People tended to get stomach problems in the summer since they changed their diet when it was hot. Most people preferred to eat cold food and pre-cooked food during summer. That food tended to get spoiled, and pre-cooked food was often not clean. People would get food poisoning after eating them.
