The protagonist of "The Cheat Pharmacist's Slow Life: Let's Build a Drugstore in Another World," Kirio Reiji, acquires the skill of "drug creation" when he is transported to another world. He uses this skill to create a variety of unique medicines not found in that world. He improves standard potions to make them easier to drink, creates cosmetics, and creates medicines useful in battle. The "drug creation" skill has many uses. This time, we'll introduce the various medicines he has created with this skill.
Potion (Excellent)
The item the protagonist creates after arriving in the other world is a potion (Excellent). In this world, potions have a disgusting taste, often described as "garbage-tasting." However, this excellent potion tastes like a sports drink and is considered delicious. Its effectiveness is excellent for stopping bleeding and treating external wounds. Its addictive taste can lead to unnecessary drinking...
Energy Potion
Also a potion, this one has fatigue recovery and awakening effects, and is called an Energy Potion. While the excellent potion tasted like a sports drink, the Energy Potion was described as tasting like a non-carbonated Oronamin C. One bottle can make even a hunchbacked old man straighten his back and regain his former mobility.
Eye Drops
This eye drop was created when Kururu asked for advice about not being able to hit the target with his arrows. While it has the same effect as any other eye drop, it's made without any chemicals. The only ingredients used in this eye drop are water, a tiny amount of salt, and shellfish broth. Reiji, who tried it, described it as "refreshing," so it's likely a refreshing type of eye drop. These eye drops continued to be sold in stores as a new product and have been well-received, with elderly people saying things like, "It makes it easier to see my grandchildren's faces."
Landen Flower Tea
At Jiral's request, I developed a medicine to cure Ferris's yandere tendencies: Landen Flower Tea. It has a relaxing effect, reduces anxiety and irritability, and acts as a mild tranquilizer. It is made from dried flower powder and grated ginger. I instructed Ferris to drink it before bed, and the next day, he slept well and appeared refreshed. Ferris experienced a similar effect to animal therapy from embracing Noella, so it seems he was particularly susceptible to the drug's effects.
Strong Landen Extract
Strong Landen Extract is an even more potent version of the ingredients in Landen Flower Tea. Created at Ririka's request to cure Kururu's man-loving tendencies, it's a terrifying item that gradually reduces libido. It's said that continued use of this drug will eventually result in "erectile dysfunction." However, Ririka rushed and gave Kururu a large amount of the drug, instead of giving him a small amount every day, which caused him to lose his libido and become obsessed. Side effects? For some reason, his face was split all the way down to his chin, giving him a dark complexion.
Deodorant
This medicine was created to help Noella, who was suffering from the unpleasant smell of moray eel flowers. As the name suggests, it's a deodorant, and just a few drops will completely eliminate the unpleasant odor. Reiji looked a bit unsure when he heard it was similar to a toilet air freshener, but its effectiveness was outstanding, and the problem was solved immediately. Both Reiji and Noella were so impressed by its powerful effects that they were left speechless. While the ingredients haven't been revealed, unlike regular deodorants, it contains no harmful ingredients, making it safe to ingest. Reiji even ate the grass covered in the deodorant.
Dishwashing Detergent
After hearing from Mina that it took an hour to do the dishes every time, dishwashing detergent was created to address that issue. The ingredients used to create the drug are unknown, and it doesn't seem like a drug at all, but it is an item Reiji created. To promote the product, he had Annabelle, the leader of the Red Cat Squad, try it, and everyone was in a frenzy over its effectiveness. Annabelle, who normally doesn't do feminine things, washed the dishes perfectly, and it became known throughout the city as the "Medicine God's Work" and the "Medicine God's New Drug." Even detergent bubbles are surprisingly rare in this world.
Beauty Gel
Flam asked him to concoct a rejuvenating elixir, and so he created this as a substitute. Although it's called Beauty Gel, it's actually a cream-like medicine that is to be applied to the face for five days leading up to the banquet. Like cosmetics, its primary effects are moisturizing and whitening. It's made with three ingredients: goat's milk, a pear-like fruit, and flower petals. After using it continuously for five days, Flam reappeared dramatically younger. However, there's no mention of it being used after that, so it's unclear whether it was sold commercially or whether Flam had exclusive access to it as a secret elixir.
Capsin Solution (Strong)
Reiji created this aggressive potion after hearing that the Red Cat Corps was having trouble with bandits. While supposedly harmless to humans, it vaporizes upon contact with air, causing severe eye pain, runny nose, and even breathing difficulties. It's made from high-proof alcohol and a spicy chili-like fruit called capsin garashi. When the smell leaked during the drug development process, people nearby began writhing in agony... Due to its extremely dangerous effects, even carrying it around is discouraged, and there's a risk of future misuse. Therefore, it's no longer available in stores, and is now only made to order by the Red Cat Corps when needed.
Charm Fragrance
This is the potion I made when Elaine asked me to make her a love potion. It's called Charm Fragrance, and as the description suggests, it's a perfume characterized by a refreshing fruity scent. It was given to Elaine as a "potion to bring out her charm." While the recipe isn't revealed, it's apparently not particularly difficult. Later, Elaine, with Reiji's help, makes a perfume to give Noella as a gift. Incidentally, giving the perfume as a gift helped Elaine and Noela become closer.
Repellent
Repellent was created after Jiral told him that animals were destroying his fields. It's made with moray eel flowers, which give off an odor that only monsters and beasts hate. Simply applying it to a fence repels the beasts. It was so effective that Jiral called it a "simple barrier." However, because it's effective against all beasts and monsters, it also has a strong effect on Noela, who is a werewolf, which led to her distancing herself from Reiji. Sales are booming, but Reiji is met with glares and denials like "Master, no!", which leaves him in tears and depressed.
Antidote
Antidote was created to calm a kodora that was raging and spewing fire in the forest. It removes harmful substances and has a sedative effect. There is a medicinal herb called arimana grass that is effective in reducing fever and relieving stomach pain, but this herb is addictive and can cause hallucinations if taken in large quantities. Reiji creates an antidote to cure Kodora, who is hallucinating and acting violently due to side effects. However, using it requires inserting the antidote into Kodora's mouth... Reiji and Noela risk their lives to administer the drug.
Kuchikun Juice
This weight loss drug was created to solve Mina's weight-loss problem. However, it doesn't actually make you lose weight by simply taking it; it simply boosts metabolism and makes it easier to burn fat. Mina had Reiji create it under the pretense that "if it's commercialized, it will sell. I'll take the drug as a test case and lose weight," but her intentions are obvious... The first time, the diet failed because she drank lip juice and snacked heavily. However, by cutting out snacks and starting exercise, she was successful. However, she regained the weight after just two weeks.
Summary of Drug Discovery in the Series
So far, we've introduced the drugs discovered in the series, but various other non-medicinal items, such as dishwashing detergent and perfume, were also discovered. Also, while she didn't actually create any new drugs, her drug discovery skills could also be used to create magical items like "elixir of youth" and "potions to attract attention." There's a good chance that "something" far removed from medicine will be created in the future, so I'm looking forward to seeing what kind of medicine Reiji will come up with.
