An Unfinished potion is the result of dissolving a clean herb in a vial of water using the Herblore skill. The unfinished potion then needs to be used on another (secondary) ingredient to make a usable potion.

They are often worth more than the herb plus vial of water itself, because training herblore by buying unfinished potions and adding the secondary ingredient eliminates the step of adding the herbs to the vials of water, which gives only 1 Herblore experience, unless the complete Factory outfit is worn.

Unfinished potions are now clearly labelled so that even someone not skilled in Herblore can know at a glance of which herb the watery solution is made. The labelling convention the herbalists have agreed upon is "[Herb name] potion(unf)". When one examines such an unfinished potion, the message is "I need another ingredient to finish this [herb name] potion." For example, the harralander potion (unf) has examine text: "I need another ingredient to finish this harralander potion."
