The Isekai Doctor: Any Sufficiently Advanced Medical Science Is Indistinguishable from Magic.

Synopsis

Amami is a kind doctor who always puts other people first. Struck by lightning and knocked unconscious, he woke up to find himself in a parallel world peopled by beast folk, with a chimera stalking around to boot! How will Amami fare as a doctor teleported to a strange world where technology is virtually nonexistent, and medicine is treated like magic? (Source: Kodansha)
