After traveling through time, she took her husband to be a food doctor

The man was wearing straw sandals, and his trouser knees and shirt elbows were patched. His skin was dark yellow, with red bloodshot eyes upon closer inspection. His cheekbones were prominent, and his eye sockets were sunken.

"Doctor..." He didn't want to close his mouth.

"What's wrong with you?" Lin Mingxuan walked over and helped him sit down.

"Look." The man pointed at his mouth and asked Lin Mingxuan to look.

Ding Xirui took a look and quickly turned his head to the side. There were four or five ulcers on both sides of the man's mouth. Just thinking about it made him cry with pain. No wonder he kept his mouth open and didn't want to close it.

"Why do you have so many mouth ulcers?" Lin Mingxuan frowned slightly and clenched his fingers.

"I don't know either." The man said vaguely.

"What do you usually eat?"

"Rice porridge." His eyes flickered.

"Let me take your pulse." Lin Mingxuan said.

The man wiped his hands on his clothes and then held them out.

After a moment, Lin Mingxuan said:

"Your lung and kidney yin are deficient, and the virtual fire rises to your mouth, causing mouth ulcers."

"Doctor, I received a hundred coins yesterday. Can you cure me? I will go back today. If you can't cure me, I won't treat you."

"It can be cured, don't worry."

Lin Mingxuan prescribed donkey-hide gelatin lung-nourishing soup and gave it to the apprentice in the store to get the medicine. Ding Xirui followed and whispered a few instructions.

"Take this medicine for three days. When you go home, eat more fresh vegetables and don't drink alcohol..."

The man suddenly started crying.

"Thank you, doctor. I..."

"Don't be anxious, speak slowly."

"People where we live often get mouth ulcers, which heal in a few days and don't grow so many. Mine has been going on for more than ten days this time. My family doesn't have much money, so I went to the city and worked for others for a day... Thank you, doctor." The man said, wiping his tears with his sleeves.

Ding Xirui's nose was sore. Alas! He had endured the pain for so long, lacking food and clothing, and finally collapsed.

Wait, he said that people over there often get mouth ulcers, his complexion is so bad, and he only eats rice porridge on weekdays...

"Brother, how do you make rice porridge at home?" Ding Xirui asked.

"There's only water and rice. My mother usually cooks for me, so I don't know."

"Is your home far from here?" Ding Xirui asked.

"It takes half a day to walk, but if there is a carriage, it should only take less than half a day." The man replied.

"Let's take you back."

"How can this be possible?" The man was stunned.

Lin Mingxuan pulled Ding Xirui's sleeve.

"The people in the same village have similar symptoms. I want to go over and investigate."

Lin Mingxuan stood up and frowned as he looked at Mr. Zhang who was holding a candy bar and looking at them from behind the counter.

"You stay here, I will take Nanxing and Banxia with you. If you are still worried, I will bring another younger brother with you." Ding Xirui continued.

Lin Mingxuan did not answer.

"Don't worry, I'll go over and take a look. If we can't find anything today, we'll come back immediately and we'll be home before night."

"Okay then." Lin Mingxuan said, he turned his head to look at Nanxing and the others, and then said: "Take good care of the young lady."

"Ah."

Nanxing went home and drove the carriage. After Ding Xirui explained everything to the patient, they went to the city gate to wait.

The tall apprentice Xiaoqiang followed them with shining eyes.

The carriage left the city, and the official road was less crowded. After more than an hour, they arrived at the man's village. It was lunch time, and smoke was curling from every household, but the smoke seemed a little too much.

The man led them to a wooden gate. Two thatched houses, a semi-open kitchen, two trees, and a vegetable patch were all that this family had.

"Mom, I'm back."

The woman in the yard looked up and saw her son with a few strangers. She immediately straightened up and walked over.

"Mom, this is the doctor from the clinic. Come to our house and take a look."

"Ah Sheng, what are you doing standing there? Please invite the guest in."

"it is good."

The wooden door opened and Ding Xirui and others walked in.

"This is really, the house is not clean..." She hurried to the front of the house, moved a few small stools, and wiped it with her sleeves.

"Sister-in-law, don't bother, we are not tired." Banxia walked over to help.

"That won't work. Guests are here and we have to entertain them." She wiped the sweat from her forehead.

"Mom, I'll go light the fire." Ah Sheng walked to the stove.

The sister-in-law looked at the few people, then at the pot, her eyes flickering.

"We brought food, sister-in-law, don't be busy, let's eat together later."

Ding Xirui opened the small package, took out a few cakes and placed them on the "table". It was called a table, but it was actually a large tree root that was sawed off.

"I'll make some food, and you guys can take a rest."

"Need not……"

The eldest sister-in-law walked quickly to the vegetable patch and just squatted down, but immediately stopped. She patted herself and murmured:

"Look at my brain, it's useless. I forgot about Gabonese grey water."

Gray water?! Sure enough, there was something wrong with this meal.

Ding Xirui walked over quickly and stopped her.

"Madam, what are you doing?" The sister-in-law looked confused.

"Sister-in-law, you can't add this water. It's because of this that your Ah Sheng got sick."

"No way...we have been eating it for many years..." The sister-in-law's hands began to tremble.

"You add lime water to the porridge to make it thicker, right?"

"Yes. The food is not enough, and we can't have watery porridge. A few years ago, someone came back from abroad and asked us to add some ash water. I tried it, and the porridge did taste better."

"Think about it, is it from that time that you and Ah Sheng began to have mouth ulcers intermittently?"

The sister-in-law lowered her head and began to recall. After a moment, she raised her head:

"Madam, it seems to be the case. This gray water can't be poisonous." She looked at Ah Sheng, her eyes full of guilt.

"Don't worry, sister-in-law, it's not poisonous. However, the good things in the rice porridge will be destroyed by the ash. If you eat that kind of rice porridge for a long time, you will get mouth ulcers, your complexion will turn bad, and it will affect your stomach."

Penghui water is alkaline water, which will destroy the B vitamins in the porridge. This village is very poor and lacks other sources of B vitamins. Over time, oral ulcers, skin diseases and gastrointestinal diseases will occur.

"Ah..." The sister-in-law shed tears.

"Sister-in-law, don't worry. From today on, just don't add lime water."

"Yes, mother, the doctor said that thing is not good, so let's not add it." Ah Sheng heard the conversation and said.

"Well, this is really..." She sighed.

Nanxing and Banxia were a little confused. Adding ash water to corn is good for the body, but rice porridge cannot be added. What on earth is ash water? Xiaoqiang was curious. He picked up the bowl of ash water and smelled it.

"Sister-in-law, people in the village always add it when cooking, right?"

"Yes. The porridge becomes thicker, who doesn't like it?"

"Where does the village head live? Tell him immediately and have him tell everyone that it can no longer be used."

"The headman's house is upstairs, in that big room." The eldest sister-in-law raised her head and pointed to the tile-roofed house not far away and said.
