To the north of the Far Sail Collar, it belongs to Aiwen's high-standard biological laboratory.

Grunt... Grunt...

In the glass still, green broken leaves, red, yellow, and purple petals are tumbling in the boiling water, and the scorching steam rises with the essential oils separated from the oil-storing cells.

Through the condenser tube above the still, it continues to flow into a spiral condenser surrounded by cold water on the outside, and the last drop drops into the collection bottle below.

With a sterile gloved hand, remove the clear collection bottle that has been filled with the oil-water mixture, and replace it with a new one.

Da!

Using the lab equipment at hand, young people in protective suits skillfully separate the oil and water, and then fill the extracted essential oil into several glass bottles.

"Teacher, the essential oil of the split-leaf pineapple flower has been extracted, do you want to take a look?"

Distillation is currently the most commonly used method for extracting essential oils, and there is no one.

About 95% of all essential oils are extracted by distillation, and others are pressed and extracted, which are suitable for medicinal ingredients with different properties.

Now this simple preparation process does not need to be done by Ai Wen himself at all, and it is more than enough for the second disciple Calvin to go into battle.

After taking the finished product in Calvin's hand, Ai Wen did several sets of control killing tests on the collected [Super Cyst Fungus], and got the expected results.

With the test record in hand, he walked over to the MD who was working on the other end of the lab.

"Dr. Taylor, Split-leaf pineapple flower essential oil is stable in nature, has an excellent killing effect on this pathogenic bacteria, and is also the most suitable for large-scale preparation. I think that's the medicine we're looking for. ”

"Split-leaf pineapple flowers? I'll take a look. ”

Shortly after Evan and his party parted ways with Dr. Taylor, Gary led a group of guards to find him and escort him to the Far Sails.

When the first batch of [cyst attendants] attacked by the Yuanfan Collar, causing panic infections, they helped a lot in time. Of course, it was not only for the vocation of a doctor, but because of the great value of being a professional wizard, he was the guest of honor of the marquis.

By the time Evan and his entourage had traveled through thick and thin, across the entire New Granada Vice-King and the Golden Sea to the Far Sail Collar. Dr. Taylor, who had already prepared for it, used the knowledge inherited by the "Vesalius School" to lock in a series of targeted herbs using the original strains as a medium:

Golden flower, rabbit wind, crab beetle, hairy bee fighting green, split-leaf pineapple flower...

In fact, those who look down on Chinese medicine do not know that even the original Western medicine is mostly from the roots, bark, and flowers in the vast natural world.

It's just that pharmacists have researched and extracted the most effective, single-ingredient chemical products. This is what Westerners later extracted and made by chemical methods, which is purer and more singular than traditional Chinese medicine.

For example, aspirin, another name for acetylsalicylic acid, is a synthetic substance produced by the synthesis of the active ingredient "salixyl alcohol", which is named after a type of willow "silk willow".

The original source of the API was the resin extracted from the bark of the willow tree and the sap extracted from the leaves of the willow tree.

Quinine is a cure for malaria, and it also comes from a flowering evergreen plant, the famous cinchona tree.

Originally, the bark of the cinchona tree itself was widely promoted as an antimalarial drug. Two hundred years after it was introduced, a pharmacist extracted an alkaloid called quinine, which transformed it into a conventional Western medicine.

At present, in this Age of Discovery, with the gradual development of experimental medicine.

Natural plant extracts or essential oils are beginning to replace the complex bottled decoction derived from the wizard's "potions" as an important weapon in the hands of apothecaries, and will soon become the main form of medicine in the mundane world.

If in another one or two hundred years, when natural substances are either raw materials for the manufacture of pharmaceuticals or reference samples for artefacts, chemists will produce more and more chemical compounds that are not found in nature.

Of course, they are now in the initial stage of medical science, and they are far from having the corresponding conditions and knowledge system.

Extracting the active ingredient directly from the plant is by far the easiest and the only way to produce enough medicine to tackle a disease as quickly as possible, and it is simpler than chemically replicating its complex effects.

As for the pharmaceutical giants in modern society, why they never promote these complex natural medicines is not because they are not effective, but simply because they are difficult to obtain patent rights for the corresponding drug formulas and make profits from them.

This is not the case for Aven.

In collaboration with Dr. Taylor, they finally chose a plant that is widely distributed in the subtropics and tropics of the New World from several alternative plants: the "split-leaf pineapple flower" of the genus Artemisia in the Asteraceae family.

The essential oil ingredients extracted directly from it can exert a strong killing effect on the [super cyst fungus] that has been modified by witchcraft, and has a broad-spectrum inhibitory effect even against a variety of other germs.

In particular, this plant grows in a wide range, and even the simplest and crude distillation extraction method will not destroy the active ingredients, which is convenient for large-scale preparation.

And unlike the antibiotics that Evan is planning to make, it can have strong side effects on humans, and allergy testing must be done in advance when using it.

This also means that they don't need to conduct too complex human experiments to go straight to market!

"I don't think there's a problem, Mr. Aven. Although it is not the one with the best bactericidal effect, this drug can fully meet all our current requirements. ”

After reading the experimental report and the comparison of several alternative drugs, Dr. Taylor also agreed with Evan with some excitement.

Sand.. Sand.. Sand..

By the way, from the professional point of view of a good doctor, at the very bottom of that report was left a prescription for how to use this new drug.

Combined with this essential oil named "Chloroby" because of its color, and several auxiliary medicines, it is expected to be enough to cure the second generation of patients infected by "Cyst Attendant" within three days.

However, after being absorbed too much nutrients by the cyst fungus, weakness is inevitable for a long time.

As for the first generation of patients directly infected by the "plague cloud", it is not certain for the time being. Because they don't have that kind of patient at hand for the time being, even if there are those who come around, they have already been burned as a source of infection.

And Evan was very suspicious that after killing two members of the "Plague School", they would dare to continue spreading germs with such fanfare.

Although this time, because of various coincidences and the pertinence of the road, they were planted in their own hands.

However, it is not possible to question the viability of the "epidemic school" and the powerful threat to ordinary people, if you are a low-key person, you can at least get a lot of nourishment.

Ai Wen couldn't help but think deeply, just a germ in a crystal cave can cause such a big trouble, so what kind of power will it have after the outbreak of various pathogens that are not well known to humans?

Even the common diseases that are very popular among ocean-going sailors: malaria, yellow fever, bloody diarrhea, edema, colds, parasitic diseases... These are more troublesome than the other, but they cannot be solved by relying on strength.

So when Calvin left the lab with the report and the warrant issued by Aven, gathered the raw materials, and gathered the craftsmen to prepare for the large-scale preparation.

Ai Wen asked the doctor who was tidying up the experimental equipment next to him:

"Dr. Taylor, after settling the matter here, I wonder if you have any other plans?"

After finding the special medicine, Taylor, who had just breathed a sigh of relief, didn't expect Evan to ask this question, and after thinking for a while, he also answered him very honestly:

"I may choose to continue my journey to the magical New World, to improve my medical skills as I continue to heal. If I could make some kind of groundbreaking medical achievement and leave a mark on the medical code, it would not be in vain for my decades of medical practice. ”

Ai Wen also knew that this seemingly middle-aged doctor was actually close to seventy years old. It's just that because of the nature and special knowledge of wizards, his physical condition is far better than that of ordinary people.

And it would be inconceivable that such an "old man" could cross the ocean across the Black Sea to the New World without firm conviction or obsession.

Therefore, after hearing his words, Ai Wen must have felt that his plan this time should be stable.

He stared into Taylor's eyes and said very sincerely:

"With such great ambitions, you are destined to become a great doctor.

It just so happens that I have a little idea that might inspire you.

Essential oils derived from plants have a variety of effects because they contain specific natural ingredients. ”

When the other party couldn't help but listen, Evan threw a bombshell.

"And I also discovered a special class of substances produced by a certain microorganism, which can be used to treat various bacterial infections or disease-causing microbial infections, which I named: antibiotics.

Moreover, they have a much better antibacterial effect than natural plant extracts, and are destined to be a blessing for countless patients suffering from diseases.

On top of that, it's a whole new class of drugs, and his inventor will be destined to... Leave a name in the history of medicine!"

Looking directly at Dr. Taylor, who was already red and short of breath across from him, Evan finally showed a devilish smile:

"I haven't completely completed the experimental part, and the second author of the paper is currently missing, I don't know..."

"Please give me this opportunity to contribute to the cause of human medicine!"

Looking at Dr. Taylor, who had already bowed to the end in front of him, Evan was in a very happy mood and clenched his fists lightly:

"Ship doctor, get!"
