Chapter 282 The most powerful scented tea in history
"I should... still be able to find some fresh ones." David's rest of his eyes swiped across the page and paused at the growth cycle column.
"The flowering period is almost over now, but at this time every year we purchase a batch of drying reserves, and there will be some in the inventory that we haven't had time to process."
The two came to the clinic pharmacy and picked out a plant called "Purple Bell" among a pile of soil-covered plants.
The flower color makes it particularly conspicuous among all herbs, and you can find it without much effort. In addition to the purple flower variety in the picture book, there are also light yellow and reddish varieties. The same appearance is like a bell string, and it is plush when you buy it.
a feeling of.
They had been out of the soil for some time and were hanging dry like pickles when they were lifted.
Even so, in Kraft's eyes, this is a charming pickle.
"Get a jar, not the lead one."
It’s similar to how to make pickles. After weighing it, cut it into sections and mince it, throw it into a medicine jar, add water and boil it. As for how long to cook it, it’s not clear. Kraft left this job to Dr. David and let him rely on his experience.
play.
The latter skillfully controlled the temperature of the furnace, simmering the liquid over medium heat until it boiled, then pulling out part of the charcoal and switching to low heat to keep the water scalding hot without boiling.
Uniform bubbles constantly emerged from the bottom of the jar, and the stirring brought up colorful plant debris, which rose in the center of the increasingly thick orange soup and scattered and fell like snow flakes.
When the solid matter became noticeably lighter in color and the soup began to resemble some drink in appearance, David removed the jar and poured the contents into the glass container Craft had brought.
From the appearance point of view, this is a cup of scented tea. It is bright and transparent as a whole, with dots of colorful powder floating in it. It looks pretty good.
If you get closer and smell it, you can still smell the faint fragrance of grass and trees, like those unknown wild flowers and grass mixed and heated after summer showers. The finished product is much better than the lead-boiled hodgepodge before.
If it appeared at the dinner table, I believe most people would not object to drinking such a drink.
"What's next?" David placed the steaming glass container on the coaster, "Take a sip?"
His love for medicine has prepared him. It is toxic, but after all, real cases of poisoning are rarely seen. Maybe the toxicity is not that strong?
"Taste it, but not like this." Kraft poured half of the medicinal solution into a second identical container, added an equal amount of water and mixed well, then added half of the diluent to another glass container.
After four times, he got the drug with a concentration of only one-sixteenth. Considering the conditions, the actual deviation may be slightly different, but not too much.
The last liquid solution was almost completely colorless, so clean that people couldn't help but trust it.
Kraft rejected David's request to help test the medicine. Although he was 90% sure that there would be no major problem, this was not a matter of probability, but an ethical issue.
He picked up the last glass container, brought it to his mouth, took a hesitant sip, and let the cooling liquid slide over his tongue.
That little amount didn't reach the stomach, but disappeared in the esophagus, moistening the dry mouth.
Nothing happened, his breathing was steady, and the rhythmic heartbeat was contained in his chest. Kraft realized that he had thought too much. Perhaps boiling itself was not a good way to extract active ingredients, and it was already quite safe after dilution.
He picked up the glass container again and took a big sip. The liquid level was reduced by a quarter. Under David's curious and concerned eyes, he pressed the radial artery of his left wrist to estimate his heart rate.
[About sixty times per minute]
It is completely within the normal range. Excellent local bodies have a clock-like heart rate, which is usually maintained at the lower limit of the normal heart rate of about 60 beats per minute.
After calming down for a while, the professor took a sip of the third diluted medicine and closed his eyes to feel the changes in his body.
[still more than sixty times]
Is it really a psychological effect?
Craft simply drank half of the liquid in the glass, calmed down and started counting again.
After half a day of screening, taking medicine, and experiencing several emotional ups and downs, he felt that he should be a little tired, but after squinting his eyes, sleep did not come as expected. His brain counted subconsciously, creating various images of the changing light spots on the back of his eyelids.
Imagine.
The nervous system is still slightly excited, and some sensations become clearer after closing the eyes, such as the pulse touch on the fingertips, and some feelings that occur only during exercise and intense emotions. Something seems to be beating on both sides of the head and gradually develops into slight pain.
, which is a sign of arterial filling and increased blood pressure.
He made another count.
【Less than sixty times】
It's about fifty-four to fifty-six times, which is a little lower. For people who exercise all year round, a heart with a stronger pumping function only needs a lower heart rate to maintain supply.
But this is a sign,
Kraft shook the liquid in the cup. He could have had a safer and more troublesome method, but that was too long. The idea of immediately witnessing the birth of a famous drug for later generations outweighed the possible risks.
One-third of the medicinal solution disappears in the mouth, and the liquid slides coldly along the esophagus and enters the digestive tract.
【Fifty times】
After a few minutes, Kraft finally noticed a significant slowdown in his heart rate.
David reminded aloud: "Professor, your face is a little red."
In fact, without reminding, you can feel that a sufficiently obvious effect is taking place in your body. The cold medicinal liquid is transformed into an effect that may be described as "warming". The myocardium is like an arm lifting a heavy object, slower and more powerful.
It works to pump out a large amount of blood.
Improved cardiac output will be reflected in improved physical strength in heart failure patients, as if the body has been warmed and nourished, and its former vitality has been restored.
But Kraft prefers to call it "inhibiting the sodium-potassium pump." The drug regulates myocardial muscle strength by interfering with cardiac electrophysiology, which can improve symptoms, but has little significance in improving prognosis and extending life.
If you continue to ingest it and reach a toxic dose, the exact opposite effect will occur - the heart rate will begin to accelerate instead, and rapid ventricular arrhythmia will occur. At that time, antagonist drugs will have to be used.
As for where the antagonistic drugs are? Sorry, there really aren’t any at the moment. They can’t be cooked.
So it's time to stop.
The source of a large category of cardiotonic drugs, legendary plants, that only existed in the corners of textbooks and lesson plans in my memory, came to me when I needed them most.
It may be the oldest anti-heart failure drug. It was found to be useful in treating edema very early, but its specific pharmacological mechanism was not clarified until modern times.
Kraft held the glass container high, feeling a slight headache like drunkenness. He couldn't tell whether it was the effect of drugs or emotional excitement. "Can I rename it?"
"Well, theoretically, as the discoverer of a definite pharmacological effect, you could name the derivative drug..."
"Just call it digitalis."
"What does this mean? I thought you wanted to use your family name or your own name." David still didn't understand what happened. He only knew that it had an effect, but adding a brand new noun would make the exam more difficult.
The behavior is instinctively repulsive.
"Don't ask, the name is kind!" After confirming the identity of the plant, a large number of ideas emerged one after another, from quantitative medication to confirmed indications under limited conditions, quickly filling the processing threads of the brain.
These must be used on patients. It cannot be compared with just trying it on yourself. It requires more caution and more time.
But it seems that there is something close to human organizations around him, but not human at all, which can just meet his exploration needs.
