Clean marrentill

Marrentill is a low-level herb used in Herblore. It is generally combined with Unicorn horn dust to make anti-poison potions. It can also be combined with 2 Clean guam and a Clean harralander to make Guthix rest tea (after reaching the appropriate point in One Small Favour or with 15 Swamp tar to make Marrentill tar.

However, many players tend to keep Marrentill for a different reason. In player-owned houses, made through the Construction skill, incense burners can be set up, but need to be lit with this herb. If a player does this correctly, he or she can earn a set percent of Prayer experience per bone used. A Marrentill gives 3.8 Herblore experience for cleaning it, while making into an anti-poison potion gives 37.5 Herblore experience. Marrentill may also be obtained as a drop by Suqah at the southern end of Lunar Isle.
