The Anime Lad
A young pharmacology researcher is reincarnated in a medieval parallel Europe as a ten-year-old pharmacist's apprentice. He retains modern medical knowledge and gains unusual abilities for detecting disease and working with materials. Local treatment is unreliable and expensive. He responds by pursuing better medicine for ordinary people, thereby resuming work immediately.
Super Eyepatch Fox
Modern pharmacological knowledge enters a fantasy society where dubious treatment and guild control keep effective medicine away from common people. The reincarnated researcher has diagnostic and material abilities suited to the problem. As a young pharmacist's apprentice, he begins applying science to a system shaped by privilege and poor practice.
Gigguku
I did not expect a pharmacy counter to carry this much fantasy momentum. A reincarnated researcher arrives with modern pharmacological knowledge in a society where ordinary people cannot reliably obtain effective medicine. His abilities are huge, but their target matters more. Correct diagnosis becomes exciting because it can change who receives real care.
Father's Basement
The protagonist arrives with knowledge and magical abilities tailored so neatly to medicine that ordinary technical tension should collapse. The premise finds resistance in access. Effective treatment is restricted by guild power and high prices, while dubious practice remains common. Overwhelming ability at least points toward a concrete social problem instead of empty status.
