Herb

Herbs are items used to make most potions with the Herblore skill. There are many herbs, each of which have a "clean" and "grimy" state. Herbs must be clean to be used in potions. Players can clean grimy herbs, provided that they have the minimum required Herblore level (see below).

When making potions, players must combine a clean herb with a vial of water, coconut milk, vial of blood or potentially other finished potions before adding a secondary ingredient if necessary. The majority of herbs can be used to make more than one type of potion, the exceptions being guam leaf, marrentill, rogue's purse, and snapdragon.

Coral takes on the role of herbs in making a number of potions; they do not need to be cleaned before use.

Players will obtain all herbs as grimy through Farming, though they can be obtained clean from other players, at the Grand Exchange or through various monster drops. Players can clean grimy herbs by left-clicking on them, gaining a small amount of Herblore experience points. Alternatively, players can cast Degrime resulting in half the experience. Each type of herb has a minimum Herblore level requirement that players must have to do so. Players who do not have the required Herblore level to clean a herb can take it to Zahur, the herbalist in Nardah, who will clean it for 200 coins.

Bug:

When auto cleaning herbs, often only one will be cleaned instead of the whole inventory.

Herbs, grown in herb patches, are a variable yield crop, meaning the resulting number of herbs harvested from a grown plant changes depending on a number of factors, including the player's Farming level, compost usage, item bonuses (magic secateurs and the Farming cape), diary bonuses, as well as a linear function that is unique for each herb type (up until level 99 Farming, where the value is the same for all herbs). For more information on variable crop yield, see here.

Typically at level 99 Farming, with magic secateurs and a Farming cape, one can expect 4.712 herbs with no compost, 6.282 herbs with regular compost, 7.853 herbs with supercompost and 9.423 herbs with ultracompost from a fully grown plant. A practical use calculator, which can be adjusted for one's specific circumstances and will give a more accurate result, can be found here.

Players can obtain grimy herbs via several methods, perhaps most notably by growing seeds via the Farming skill and as drops from monsters. They may also receive herbs from the Sorceress's Garden minigame, from their kingdom on Miscellania and Etceteria, from the sinister chest, or as a reward from the Pest Control and Temple Trekking minigames.

Grimy herbs are available as drops from various monsters, including very low-level opponents such as men in Lumbridge. Some monsters drop more herbs than others. Toadflax, snapdragon or torstol are not on the standard herb drop table, these can be obtained from more specific sources; See their respective pages (and the pages of their grimy variant).

• Men and women drop a surprising variety of herbs including high level herbs. They are only level 2 and are found all over Gielinor.
• Chaos druids are only level 13, and drop a lot of herbs. Players can find them in the Taverley Dungeon, Edgeville Dungeon, in a tower north of East Ardougne, and in the Yanille Agility dungeon.
• Cave crawlers are Slayer monsters that drop both herbs and ingredients, they are poisonous, so an Antipoison is advised.
• Aberrant spectres are Slayer monsters that drop large numbers of herbs. They can be found in Morytania Slayer Tower and also in the Stronghold Slayer Cave. Level 60 Slayer and a Nose peg or a Slayer helmet are required.
• Chaos druid warriors in the Yanille Agility dungeon drop a wide variety of secondary ingredients as well as herbs. However, being stronger than ordinary chaos druids, they take longer to kill, which makes them slower for herb gathering.
• Basilisks are Slayer monsters which drop herbs very often. They have a combat level of 61 and are located in the Fremennik Slayer Dungeon. A mirror shield and a Slayer level of 40 are required to kill them. As with chaos druid warriors, while their drop rate is good, their higher combat makes them take longer to kill than other herb droppers.
• Flesh Crawlers in the level 2 Stronghold of Security drop herbs frequently, are aggressive to all levels, and can be slain relatively quickly, which makes them ideal for gathering herbs. They hit relatively low for their level, but their attacks are fast, and can be very accurate. In addition, they are frequently crowded on most worlds.
• Banshees in the Slayer Tower drop fewer herbs than chaos druids, but also drop large quantities of noted pure essence. Level 15 Slayer and earmuffs or a Slayer helmet are required.

Players can also kill Salarin the twisted for the Sinister Key, which opens the sinister chest. Players will receive two harralanders, three ranarr weeds, one irit leaf, one kwuarm, and one torstol. Both Salarin the twisted and the Sinister chest are found in the Yanille Agility dungeon, and players need an Agility level of 67 to reach him. Salarin the twisted, the Chaos Fanatic, and the Magpie impling are currently the only non-player characters that drop the sinister key.

Salarin the twisted can only be injured by one of the four elemental strike spells: Wind Strike, Water Strike, Earth Strike, or Fire Strike. Chaos druids and Chaos druid warriors are also found in this area.

Players can also grow their own herbs from seeds via the Farming skill. They need to obtain the correct seeds for the type of herb they wish to grow, and plant them in a herb patch. At high Farming levels this can be a very effective method of obtaining experience in both the Herblore and Farming skills.

The herb patches unlocked by completing Making Friends With My Arm and My Arm's Big Adventure can be useful, as herbs grown in them cannot become diseased.

With the easy tier of the Kourend & Kebos Diary complete, the allotment, herb, and flower patches in Hosidius will no longer become diseased.

With Champion status in the Fortis Colosseum, requiring 16,000 Glory, the herb patch west of Civitas illa Fortis will no longer become diseased.

Players who have completed the Throne of Miscellania quest can receive grimy herbs from Miscellania (see Managing Miscellania). Players pay an average of 800 coins per herb collected using this method, and receive up to 80 grimy herbs per day, all tarromin or above, if they have enough money in the coffers and have herb-gathering set to maximum.

Player can obtain clean herbs from the Sorceress's Garden minigame, in which players work their way through a maze to reach a herb patch. Having reached the end, players can pick two random herbs before being teleported back to the beginning of the maze. This takes approximately 50 seconds. It was often crowded with bots because of the easy access and high profit of this minigame.

The lowest garden (Winter) can only yield herbs up to harralanders. The highest garden (Summer) can yield all herbs given normally as a drop besides snapdragon and torstol.

• Grimy herbs were originally "unidentified", requiring players to clean them to discover their type.
  • Jagex released Old School RuneScape with the Grimy herb system intentionally to prevent players from scamming. This was reverted back to unidentified herbs due to community demand in Patch Notes (25 February 2013). The grimy herb system later passed a poll to return so that they could be listed on the Grand Exchange.^[1]
