Cadava berries

Cadava berries are pink, poisonous berries. They can be 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 using the Farming skill. Because cadava berries are poisonous, the player cannot eat them.

One bunch of 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 nontradeable 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 drunk, 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 occasionally dropped by imps.

Trivia

 * Prior to the Varrock graphic update, cadava berries merely laid on the ground and could be picked up by players. As items they were visible as red dots on the map.
 * With the Varrock graphic update cadava berries are to be picked up from the cadava berry bushes, which, being interactive objects like trees, do not appear as red dots on the mini map. Therefore, players must be aware of the presence of the bush to find them.
 * Note that picking cadava berries off the Varrock bushes does not give any farming experience, but picking them from a player-grown bush will give farming experience.
 * Incidentally, while they cannot be traded, they can be dropped in the party room.
 * Only two uses can be found by making a cadava potion, one being Romeo and Juliet, the other strange dialogue by using it on Sophanem citizens.
 * The name "Cadava" is related to "cadaver," or another word for a dead body. This is due to the effect of being "dead" when one drinks the Cadava potion.
