I Shall Survive Using Potions!

Kaoru Nagase got caught up in a mysterious phenomenon and died on her way home from work. She skillfully convinced the higher-being that caused the distortional accident into giving her "The ability to create any potion with any effect I can think of", and to be revived in the other world with her younger self's body! Kaoru, who’s now a rather sharp-eyed 15-year-old girl, will work hard for a peaceful life in another world!

Artist Kokonoe Hibiki got replaced by Onshin Futsuu after volume 9, leading to changes in the serialization. You can find the continuation here
