Goblin's Phlegm is the name of the potion.
Lol, its not actual Goblin's Phlegm, its just the name, as far as i know (the main ingredient is a herb i think).
Tho this just adds to how bad at naming the characters are. The name just gives a really bad image so their sales are bad, among other things (づ￣ ³￣)づ
Can't get over how the characters casually research goblin's phlegm for potions. Granted, there are worse "ingredients" in other mangas, manhwas, manhuas and irl, it still makes me gag.
Random fact: Apparently irl, musk is extracted from a deer's certain organs. So maybe the author is going for a similar approach for medicine in this story.
