"Intravenous injection?"

Hearing this term from Xu Yun, Old Su blinked blankly:

"Wang Lin, what is that?"

Xu Yun thought for a moment and explained:

"Sir, whether it is a human body or an animal, there are pathways for transporting blood within, you should be aware of that, right?"

This time, Old Su didn't hesitate much and nodded:

"Indeed."

In ancient Huaxia or the concept of Chinese medicine, blood vessels and meridians are a point of contention that can easily lead to heated debates.

Chinese medicine has a standard definition for meridians, which is 'a few inches beneath the skin, can transmit air and blood'.

Therefore, some people think that 'meridian' means major blood vessels, and 'collateral' means capillaries.

Meridians and collaterals.

This is essentially the modern medical definition of blood vessels.

But some people hold a negative view on this.

They believe meridians are pathways for qi, invisible to the naked eye, just coincidentally overlapping with blood vessels in some places.

And when the issue of meridians extends, it easily leads to further debate about the existence of acupuncture points.

Acupuncture points, like meridians, currently have no solid proof of their existence.

This is one of the main reasons many people hold a negative view of Chinese medicine: if you can't find it, how can you claim it exists?

On the other hand.

In life, there are indeed some acupuncture points that one can feel the effectiveness of.

For example, Zusanli, Fengchi, Shaoshang, Hegu, etc.....

Often, when people feel unwell, pressing these points can quickly take effect.

Besides, in recent years, some results have emerged from studies on meridians.

For example, at the end of October 2021, Harvard University published a successful case of electrical acupuncture stimulation on the Zusanli point for treating sepsis in animals in Nature,

the paper code is doi.org/10.1038/s41586-021-04001-4.

In 2019, Science Advances also published a research report on acupuncture points, DOI: 10.1126/sciadv.aax1342.

All in all.

Currently, there is still no definite conclusion about the meridians and acupuncture points in Chinese medicine, and although studies have been conducted for over a decade, the specific locations of meridians remain undefined.

This is a fact and there's no need, nor can it be denied.

But at the same time.

The real effects of some acupuncture points are also quite obvious, which should not be overlooked.

Present scientific theory is still developing, with a long way to go.

To put it bluntly.

Even modern science cannot explain why a bicycle doesn't fall over once it's in motion.

Back then, the main issue of science even published a related paper, and the influence of this paper lasted nearly ten years, DOI:10.1126/science.1201959. (I'm not making this up, it's true; if you're interested, you can search it up)

Technological development and scientific explanations for certain phenomena are two different things; they cannot be generalized.

Let's return our gaze to reality.

Whether or not meridians exist, in the Inner Canon of the Yellow Emperor, the ancient ancestors had some insight into anatomy, which is recorded with concrete evidence; after all, you can see blood vessels when you slaughter a chicken.

Thus, when Xu Yun brought up the concept of blood vessels, Old Su easily accepted the idea.

Then Xu Yun paused and continued:

"Among them, veins are large-capacity vessels, specifically for collecting returning blood into the heart.

They complete systemic circulation... that is, the important pathway of the body's great circulation.

And intravenous injection refers to using special tools to inject diluted and prepared garlic juice into the human body.

Medicine thus directly reaches the affected area, yielding better results than oral and topical applications."

Hearing this, Old Su couldn't help but lower his head and feel the veins on his hand.

In modern medicine, injections are mainly subcutaneous, intravenous, and chicken... intramuscular injections.

Due to its chemical properties, garlic extract is not only ineffective when taken orally or with subcutaneous and intramuscular injections but can also easily harm the human body.

Thus, in modern medicine, the main injection method for garlic extract is essentially intravenous injection.

However, currently, there are not many garlic extract injections on the market, probably around three to five companies, with capsules still being the predominant form.

As an outstanding scientist of this era, Old Su naturally lacks neither creativity nor receptivity.

After receiving Xu Yun's suggestion, he quickly thought of some records.

He pondered for a moment and said:

"I remember that in the Records of the Three Kingdoms by Chen Shou of the Western Jin, there was an account of an unnamed doctor performing bone scraping to treat poison for Guan Gong.

In the Lingshu Chapter of the Inner Canon of the Yellow Emperor, there are also records of ancestors opening finger bones to apply medicine.

But injecting garlic juice into what you call the veins and reaching the affected area through the great circulation... This is something I've never heard of.

Xu Yun, let me ask you.

If medicines can indeed work by being injected into the body, then what would be used to achieve this?"

Xu Yun thought for a moment, gestured with his fingers:

"A long, thin, hard item, called a syringe."

Old Su was stunned immediately.

Long?

Thin?

Hard?

And makes a real poke?

Could it be that he heard it wrong before, and the process is actually called a stem vein injection, going through the perineum?

Real poke, stem vein, considering Xu Yun's background as a male actor...

Hiss!

Thinking of this.

Old Su began to look at Xu Yun with an unusual expression:

That Wind Spirit Moon Shadow sect, could it be from the Joyful Union Sect?

At this moment, Xu Yun did not notice the strangeness in Old Su's expression but took the pen and drew a simple diagram on the paper:

"This item is divided into the main body and the front needle, with the main body being about half an inch wide and half a foot long.

The front needle is only a few millimeters thick, hollow inside, with a pullable item on the main body.
