A Herb is an item used to make potions through the Herblore skill. Herbs can be received through monster drops, grown in the Farming skill, or bought from other players. When you receive a herb through a monster drop, it will be unidentified and be named simply "Herb." Before you can use a herb in any potions, you must determine what kind of herb it is by identifying it. Depending on your Herblore level, you may not be able to identify the herb. If you identify the herb, you are granted experience depending on how advanced of an herb it was.
