Spirit weed potion (unf)

A Spirit weed potion(unf) (more commonly called an Unfinished spirit weed potion) is an unfinished potion made via the Herblore skill. Players make it by using a clean spirit weed on a vial of water. If a player with an Herblore level of 34 or greater then goes on to add a Cockatrice egg to the potion, it becomes a Summoning potion, and the player earns 80 Herblore experience.
