The medicine the doctor made was delivered in stages and based off of a rare flower, the blue spider lily, he killed the doctor before he could finish it and as a result was left a demon, if the doctor had've finished it he presumably would've been immortal but not feel the need to nom people and be immune to sunlight still. He then spent ages trying to find the flower but it only blooms once 3 days a year, during daylight so no demons could find it.
