This article is about the grimy herb. For the cleaned herb, see Snake weed
A Grimy snake weed is a herb that has not yet been cleaned to make a snake weed. Cleaning a grimy snake weed requires a Herblore level of 3 and gives 2.5 Herblore experience. Once cleaned, snake weed is a secondary ingredient in Herblore, used with rogue's purse to make a Relicym's balm potion and also used as a secondary ingredient to make Sanfew serum. Adding snake weed to a vial of water will produce a snakeweed mixture.
It is involved in the quest Jungle Potion, during and after which, players can find it by searching marshy jungle vines, south-west of Tai Bwo Wannai in west Karamja, just north of the Karamja Hunter area.
Grimy snake weed is also a common drop from Jogres, which is very convenient for players with higher combat levels who are trying to make Relicym's Balm, as many reside in the cave where the other needed herb, Rogue's Purse, is found. It can also sometimes be found inside barrels.
