To my knowledge, bundles of herbs donвЂ™t drop from monsters but need to be scavenged from randomly (and very rare) generated locations in the world. You get monster mats pretty quickly but you need a вЂњbundle of herbsвЂќ to actually craft potions, bombs, and oils. On top of that gathering crafting materials is an absolute pain. For some reason the game starts you off with 2 steel swords in your inventory instead of 1 steel and 1 silver like every witcher should have. Imagine being a monster hunter without a silver sword (a sword specifically designed to fight monsters).
