Isekai Yakkyoku

It’s time to change the misguided medical care in another world by using modern pharmacy!
When a young pharmacologist gives his life to his research and dies from overwork, he finds himself reincarnated as a boy named Farma, the son of the court physician. In a new world where faulty remedies run rampant, Farma uses modern pharmacy and cheat powers to cure all the diseases around him.
