They can be obtained as drops from monsters (or reward chests/minigames), or farmed using the Farming skill. An easy way to store large amounts of (grimy) herbs (while on a Slayer task or farming), especially as an Ultimate Ironman, is by using the Herbsack obtainable through the Skill points shop.

Before they can be used in the Herblore skill, the Grimy torstol needs to be cleaned, which requires a herblore level of 75 and earning the player 1050 Herblore experience (or 210 if they are playing an Extreme gamemode, excluding any experience boosts) The player may also choose to let the Herbalist clean all of their herbs for them for a small, this will not require a herblore level but also will not provide any experience, however it will instantly clean any amount of (noted) herbs you may have.
