Limpwurt root

Limpwurt roots are used to make Strength potions at level 12 Herblore (combined with a Tarromin) and Super strength potions at level 55 Herblore (combined with a Kwuarm). Limpwurt roots, like most herblore items, are expensive when bought from other players. As an alternative to paying for them, limpwurt roots are drops from Chaos Druid Warriors, cave crawlers, cockatrice, cyclopes, hobgoblins, tribesmen, cockroach drones, turoths, and hill giants. With level 26 Farming, players can grow their own roots in a farming patch.

The Apothecary in western Varrock will make a 4-dose Strength potion if you bring him Red spiders' eggs, a limpwurt root, and 5 coins. This is the only way to make a potion on free worlds.

According to the official bestiary (now removed), Hobgoblins chew limpwurt roots, which explains the fact that they drop so many of them. And, in reference to the minitrice pet, it can be assumed that Cockatrices eat them, which is why the roots are a common drop from them.
