As long as the patriarch's Cantonese is not spoken too quickly, Hua Banzhi can still understand it.

After all, the patriarch often communicates with the outside world, and the accent can't be too heavy.

Hua Banzhi nodded when he heard this, looked at the old woman and said, "Give me your hand." ”

The old woman stretched out her wheat-colored slightly rough hand and placed it on her knee.

"My cough is also strange, I make it in the winter, and it is good at the beginning of spring, although it does not affect the work, but the cough is always ....... The old woman sighed softly.

Hua Banzhi put three fingers on her wrist, carefully tasting the pulse.

The patriarch's eyes were firmly fixed on Hua Banzhi's hand, and he even held his breath, not daring to pant for fear of alarming Hua Banzhi.

"Grandpa, don't worry, my mother's medical skills are great, grandma's illness must be fine. Zhou Guangming, who was wearing a straw hat, looked at him and comforted.

"Stinky boy, be careful that the cowhide is blown up. Hua Banzhi looked at him amusedly and said, withdrawing her hand.

"Mother, looking at your appearance, must it be okay?" Zhou Guangming looked at Hua Banzhi with sparkling eyes.

"Doctor?" asked the patriarch nervously as he looked at Hua Banzhi.

Hua Banzhi looked at her and asked, "Did you take the medicine of Chuanbei when you had your first cough three years ago?"

"How do you know?" said the patriarch as he looked at Hua Banzhi in surprise.

She was even more surprised and said, "Yes, I used to stew pears with loquat leaves from Chuanbei at that time, and loquat leaves are very common here." It worked a little for the first two days, but then it didn't work, but until now, I'm still holding on and using it when I cough!"

Hua Banzhi looked at the couple and said slowly, "This is the cause of the disease, when I coughed just now, it should be the external cold evil, and Chuanbei is a cold medicine, which has the effect of clearing heat. ”

When the patriarch and his wife heard this, they suddenly realized, and the patriarch asked again, "What does it mean to be cold and cold?"

Hua Banzhi looked at the two of them, pondered for a moment, and said, "How do you say this? It's like, on a snowy day, a person who goes out wearing less clothes, is shivering from the cold, his face is pale and blue, and he is sneezing, has just entered the room, do you hand him a glass of warm water, or a glass of ice water with ice cubes?"

The patriarch immediately said, "Do you need to talk about it? Of course you will give him warm water to keep him warm, and if you give him ice water, he will be even colder." He smiled and said, "Understood." ”

"That's the truth, in Chinese medicine, it's called the hot is cold, and the cold is hot. We maintain the normalcy of our body by adjusting the state of cold and heat in an individual. Hua Banzhi looked at them with a smile and said slowly, "Let's talk about a simple truth, for example, in winter, a piece of meat is frozen very hard, and you seem to want to thaw it, so do you choose to put it in cold water?"

"Of course it's in warm water! How long will it take to put it in cold water?" said the patriarch immediately.

That's the truth. Hua Banzhi looked at the two of them and said, "When a person just feels the cold, and has a clear nose, sneezes, chokes, pain in the back of his head and neck, and chills all over his body, these are the signs of cold. At this time, the use of any Chuanbei products will cause the cold to worsen the cold, making the cough linger for a long time. ”

"But isn't it normal to cough and take Chuanbei? We've always done this with Chuanbei stewed pears. The patriarch was surprised and said, "I didn't see anything else, and I put other spirits on it." ”

"Hehe......" Hua Banzhi smiled when he heard this, "Chuanbei, the sex is slightly cold, and there are also those who say that it is cold." Weiganping, which has the effect of moistening the lungs, relieving cough, dissolving phlegm and relieving asthma, clearing heat and dissolving phlegm, is used for fever cough, such as wind-heat cough, dry heat cough, and lung fire cough. However, the doctors of the past dynasties rarely mentioned that the misuse of Chuanbei will lead to the residue of cold evil and will not heal for a long time. ”

In the Ming Dynasty physician Miao Xiyong's "Materia Medica", he mentioned: "Cold and damp phlegm and food accumulation phlegm fire cough, wet phlegm in the stomach nausea and vomiting, phlegm drinking for cold and heat, spleen and stomach damp phlegm for dizziness, and phlegm syncope headache, evil vomiting, stomach cold and discharge, the law should be used with pungent and warm dry and hot medicine", should not use Chuanbei, this is the ancients clearly mentioned that the cold syndrome should not use Chuanbei.

However, Hua Banzhi saw more of the misuse of Chuanbei, especially after there were more Chinese patent medicines in later generations.

The conditions that cause cold and evil stagnation are obviously more than other drugs.

Hua Banzhi has seen many such children, and in late autumn, he began to cough, lingering for a winter, and then it was good to start spring, every time he met such a child.

She would ask what drugs she had used, and the answer was that she had used all the drugs of Chuanbei. For example, in the early stage of external cold and evil, Chuanbei stewed pears were used, or Chinese patent medicine Chuanbei loquat cough syrup and so on.

As long as I went to the pharmacy, as long as I said that I wanted cough medicine, the clerk recommended this Chuanbei loquat cough syrup regardless of cold and heat, which caused many people to suffer.

"Then we won't need it in the future. The patriarch immediately said.

"Look at going from one extreme to the other. Hua Banzhi looked at them and said, "Of course, Chuanbei stewed pear is a good medicine, which has the effect of clearing heat and dissolving phlegm. But this is a cold medicine to clear heat, and the pear inside is also cold, and it is used at the wrong stage when it is placed in the early stage of external cold evil. We must know a truth, that is, there is no good or bad medicine itself, if it is used correctly, it is a good medicine, and if it is used wrong, it will harm people. For example, if you use the right rhubarb, you can save your life, and if you use the wrong ginseng, you can also kill people, which is a famous saying in Chinese medicine. ”

"Then when can you use Chuanbei. The patriarch looked at Hua Banzhi and asked.

Hua Banzhi said unhurriedly, "It is only when there is dryness and heat, only use Chuanbei, such as red tongue, pulse, yellow phlegm, yellow nasal discharge, sore throat, this is a hot syndrome, when the hot syndrome, when it is with dry symptoms, it is more suitable to use Chuanbei, and when there is a cold syndrome, this Chuanbei will delay the condition." ”

"What about a situation like mine?" said the old woman, pointing to herself.

Hua Banzhi looked at her and smiled slightly, "The method is very simple, use six grams of tangerine peel and one gram of Su leaves, and soak water instead of tea." The medicinal properties of tangerine peel and Su leaf are warm, which can warm the lungs and dispel cold, and generally drink for a period of time, and the body will naturally expel the cold evil. I will prescribe you another prescription for warming the yang and promoting the lungs, it will be more effective. ”

"That's great. The couple said happily.

Hua Banzhi opened the medicine box, took out a note and a pen, wrote down the prescription, and handed it to them.

The patriarch looked at the prescription and said in surprise, "Your word?"

"What's wrong?" said Hua Banzhi as she raised her eyes to him.
