In this world, there is no such profession as a doctor, or rather, the emergence of magic and other extraordinary powers has significantly suppressed the emergence of the doctor profession.
Similar to Austin's previous life in the Western Middle Ages, the so-called "doctor" treatment methods were mostly bloodletting treatments, and there was no discovery of certain herbs in the wild that could treat certain diseases of the body.
With the popularization of divine techniques by the church and various healing potions, the intellectuals at the upper echelons saw no need to research these things. Those with knowledge strived to become scholars or mages, and those with means would directly receive divine healing from the church or purchase potions when ill. Consequently, without the involvement of intellectuals, even if farmers or other lower classes occasionally discovered a secret recipe or two, it would ultimately get lost over time and fade away.
