Jangerberries

Jangerberries are a berry used mainly as a secondary ingredient in herblore.

Uses
Jangerberries are used in Herblore to make Zamorak brews. They can also be eaten and heal 200 life points, temporarily raise your Attack level by two, Strength level by one, and restore one Prayer point for the price of one Defence level. They can also be used to make supercompost. 15 jangerberries can be paid to the gardener Ayesha to look after a prickly pear growing in the cactus patch in Al Kharid.

Jangerberries are also used in the Watchtower quest and can be randomly selected as an item needed in the quest Fairytale I - Growing Pains. If you do get this item for the Fairytale quest, it would be advisable to bring 4 or more (or simply bring Druid pouches), because the Ghasts in Mort Myre Swamp may turn it into rotten food. This makes it useless, and may result in you doing more running than necessary if it happens.

Trivia

 * Jangerberries are the only berry type that uses the standard "berry" image that are edible on their own. Dwellberries and strawberries are also edible on their own, but have a different inventory image.
