Cadava berries

Cadava berries are pink, poisonous berries. They can picked from Cadava berry bush, which can be found south of Varrock, just west of the East Varrock Mine. Members can also grow their own cadava berries. Because cadava berries are poisonous, you cannot eat them. This feature was perhaps installed as a protective measure.

Three cadava berries can be traded at the Apothecary in Varrock for a cadava potion, a quest item needed for the Romeo and Juliet quest. This potion is nontradable and cannot be created after the quest is finished. When a cadava potion is drunk, the drinker will fall into a deep sleep and (allegedly) wake up hours later.

A player can drink cadava potions in the Apothecary; once he drinks it, the screen will spin and black out, the player having collapsed on the floor. After a few seconds, the player and the screen will return to normal, and the apothecary owner will express his concern. No items will be lost from this procedure other than the potion.

Cavada berries are also a random drop of imps.

Trivia

 * Prior to the Varrock graphic update, the cadava berry merely lay on the ground and could be picked up by players. As items they were visible as red dots in the map.
 * With the Varrock graphic update the cadava berry are to be picked up from the cadava berry bush, which, being interactive objects like trees, does not appear as red dots in the mini map. There, players must be wary for the presence of the bush to find them.
 * Note that picking cadava berries off the Varrock bushes do not give any farming experience, but picking them from a player-grown bush will give farming experience.
