"Dad, little sister, you're finally back! Aunt came over, crying and asking for some brown sugar and dates before leaving."

It's said that Anxian and Antai have contracted the plague.

Anle was taken aback. "Huh?! Didn't Dad send all that medicine to their family before?"

An Ding frowned, pursed his lips, and sighed.

"It has been sent over, but perhaps the medicine didn't work."

Anle rolled her eyes, crossed her arms, and spat out.

"Impossible. They're both so energetic, they don't do any work, and they're not overworked or anything. They don't look like the kind of people who are weak or have a poor spleen. How could it not work for them?"

After pausing, glancing at An Mancang, and pressing the tip of his tongue against his back teeth, An Le uttered a helpless sentence.

"There's still some medicine left at home, Dad. Why don't you take it and go check on it again?"

An Mancang nodded, his face showing little sign of seriousness as he responded.

"Okay, I'll go over there in a bit."

If that medicine could cure even Qiu Niang's serious illness and weak constitution, then those two children will definitely be fine too.

**

Anle thought the old doctor would take two days to see her, but to her surprise, he shamelessly came to her door early the next morning to ask for advice.

"Um... little one, your prescription—"

A peaceful smile.

"It seems the old man has already used it on someone?"

The old doctor nodded hurriedly, his old face now obsequious and fawning, a far cry from the sternness of yesterday.

"I've used it, I've used it, and the effect is amazing. It worked that very night, and I was wide awake the next day and the night sweats stopped."

Yesterday, I was on the verge of passing away, but today my breathing is steady. This prescription is surprisingly effective; it's truly miraculous.

This prescription is something I, an old man, really don't understand.

Yesterday, you little brat acted like you knew something. I came here specifically to ask you for advice. Could you tell me again about that heat-related illness we talked about yesterday?

"This old man is completely baffled. Why is the diagnosis of damp-cold syndrome wrong?"

Anle smiled and asked in return.

"So you didn't leak this recipe to me, did you?"

The old doctor quickly waved his hand.

"No, no, how could I? I wouldn't dare. This recipe wasn't something I came up with myself."

Anle picked up the glass and took a sip of the chilled lemonade.

"Grandpa, let me give you an example. Do you see this glass of ice water in my hand?"

On a hot day, wouldn't a sip of ice-cold water be incredibly refreshing, thirst-quenching, and instantly make you feel comfortable?

Doesn't this ice water feel especially refreshing in the heat?

The old doctor stared at the cup in Anle's hand, puzzled, and nodded blankly, not understanding what the plague had to do with this ice water.

"On such a hot day, it seems like drinking a sip of lemon water can relieve the heat, and drinking a whole bottle can make you feel completely refreshed. Do you agree?"

The old doctor was taken aback, then realized what Anle's family did.

"Of course." Could it be that this kid is here to promote the cold drinks in her family's shop to him?

Anle shook her head with a smile.

"Actually, that's not the case. In this kind of hot weather, drinking hot water is the most suitable thing to do, as hot water can relieve the heat, not drinking ice-cold water."

The old doctor was stunned again upon hearing this. Wasn't he being asked to buy cold drinks?

"Grandpa, you see, this is your wrong way of thinking. You should actually do the opposite."

It's wrong to think that eating hot food is warmer in winter and that eating cold food is more satisfying in summer.

You've only seen the surface; the correct approach is exactly the opposite.

In winter, a person's Qi and blood gather in the five internal organs, providing great protection for them.

At this time, we should eat some cooling foods to dispel the heat accumulated in our internal organs, otherwise it can easily cause discomfort symptoms of internal heat and inflammation.

In the sweltering heat of summer, blood circulation becomes smoother, and this flow of qi and blood radiates outwards from within.

At this time, the internal organs are in a state of deficiency. Drinking cold drinks will only increase the burden on the body and cause harm. In fact, eating some warm foods can better protect the body.

I wonder if the old man agrees with this statement?

After Anle finished speaking, she saw the old doctor fall into deep thought, lost in thought because of what she had just said.

It took him a while to come to his senses, and he nodded as if he agreed, feeling that what was said made some sense.

"That does seem to make sense."

Anle's smile deepened; she had merely uttered a few words about health preservation that most people in the 21st century understood.

It's unbelievable that in this world, they don't even understand the most basic principles of health preservation, and their medical knowledge is truly appalling.

This also gave me a better understanding of the underdeveloped state of medicine in the world.

"The same principle applies to the symptoms of this plague. Feeling cold is just a symptom and does not mean that you need to treat it by expelling the cold."

The cause of this plague is generally due to the combination of pathogenic factors and dampness. It can be treated by using some traditional Chinese medicines that clear heat, detoxify, and remove dampness.

A very small percentage of people require individualized treatment due to their unique physical differences.

For most patients in this group, some detoxifying drugs that clear heat and cool the blood can be selected.

This plague is caused by heat toxins. The special feature of the prescription I gave the old man is that it clears away both qi and blood.

This prescription is made by decocting the following medicinal materials: gypsum, rehmannia root, rhinoceros horn, coptis root, gardenia fruit, platycodon root, scutellaria root, anemarrhena rhizome, red peony root, scrophularia root, forsythia fruit, licorice root, peony bark, and fresh bamboo leaves.

It contains a large amount of raw gypsum, which is pungent, sweet and extremely cold. This is a superior medicine for clearing heat from the Qi level. It can clear heat and purge fire, relieve irritability and quench thirst, and is mainly used to clear heat from the lungs and stomach.

The stomach is called the "sea of ​​water and grain," and the qi and blood of the twelve meridians all come from the essence of water and grain transformed by the spleen and stomach. Therefore, when the heat in the stomach is cleared, the fire in the twelve meridians will naturally disappear.

The combination of gypsum with anemarrhena and licorice is based on the principle of Baihu Decoction, which clears heat from the Yangming Qi level and preserves body fluids.

It is also said that forsythia and bamboo leaves are light and refreshing, providing an outlet for evil qi, and can also clear the mind and relieve vexation.

The combination of Coptis chinensis, Scutellaria baicalensis, and Gardenia jasminoides is based on the principle of Coptis chinensis Decoction, which aims to clear away excess heat in the three jiaos (upper, middle, and lower burners).

Rhinoceros horn, peony bark, rehmannia root, and red peony root are specifically for cooling the blood and detoxifying, nourishing yin and removing blood stasis. They are based on the principle of Rhinoceros Horn and Rehmannia Decoction, which clears heat from the blood and protects yin fluids.

Scrophularia, Platycodon, and Glycyrrhiza clear heat, expel pathogens, and soothe the throat. Platycodon can also carry the medicine upwards.

When used together, these herbs clear heat from both the Qi level and the blood level, effectively treating a severe case of excessive heat. This makes it an optimal remedy for epidemic diseases.

The old doctor looked bewildered, seemingly understanding yet not quite, staring at Anle with a face full of question marks.

There was a lot of pharmacology in this explanation that he didn't understand.

Furthermore, what exactly did this child rely on to prove that the plague was a heat-toxin disease?
