What does the combination of Ming and Dan mean?

"Ming" and "Dan" together mean "recover from illness"

In other words, each one is related to medicine, and the source of this sentence is the ancient medical text "Biography of Hua Tuo in Wei Zhi". Both of them were cured the next day.

Hua Tuo was a famous imperial doctor in the late Eastern Han Dynasty. He is proficient in internal medicine, surgery, gynecology, pediatrics and acupuncture, and his medical skills are brilliant and his diagnosis is accurate. According to legend, when Hua Tuo treats a disease, he can often prescribe different prescriptions according to the changes of the four seasons and the physical quality of the patient.

The story goes like this:

On one occasion, state officials Ni Xun and Li Yan went together.

Hua tuo was invited to see a doctor, and their symptoms were completely similar.

Accompanied by headache and fever, Hua tuo separated after listening to it.

Don't touch the pulse of two patients in detail before driving.

Give two different prescriptions: what Ni Xun got was

Laxative, but Li Yan took the antiperspirant.

Two people see the prescription, can't help but curiously ask hua tuo:

"We both have the same symptoms and the same situation.

Why do you take different medicines? "

So Hua Tuo explained, "You two are the same.

It's just a symptom of illness. Ni Xun's illness came from the inside.

It was caused by eating, but Li Yan's illness was caused by eating.

It is caused by exogenous wind and cold. The reasons are different,

Of course, I have to prescribe a different medicine for you.

Drugs for treatment. "

Sure enough, Ni Xun and Li Yan didn't take too much medicine.

It took a long time to recover.
