Marrentill potion (unf)

Marrentill potion (unf) (more commonly called an Unfinished marrentill potion) is an unfinished potion made via the Herblore skill. Players make it by using a clean marrentill on a vial of water. The resulting mixture appears purple in colour.

Players can make this into antipoison by adding unicorn horn dust at level 5 Herblore.
