The potion boosts experience for both cleaning grimy vine herbs and making juju potions. The potion does NOT boost experience from making unfinished juju potions even if the player is wearing a Factory outfit. The player will receive regular cleaning experience with the outfit, though. Making this potion grants 170 herblore experience and requires a clean samaden and a Guthix vine. Each dose of potion lasts for 6 minutes. You will get a notice in your chat box when your potion's effect is about to wear off (about 30 seconds before) and also when it has worn off.
