Queen Bee began supplying the Resistance with her honey sometime after the Shadow Lord's invasion of Deltora. In order to keep both herself and her sons out of danger, Queen Bee sold the honey to the Resistance under the label of Quality Brand Honey.
The Maze of the Beast
Dain was carrying a jar of honey with him when he saved Lief, Barda and Jasmine from two Ols. He used some of the honey to heal Barda after he had been injured during the battle. Dain took some honey when he nearly passed out after suffering a sprained arm and several broken ribs. When the companions arrived at the Resistance stronghold, Lief used the honey's "Quality Brand" label to realise the hidden password to get inside. Lief later gave some honey to Jasmine after the Ol attack aboard the River Queen.
The honey has powerful healing properties. Eating so much as a spoonful is enough to give strength to someone who has survived an Ol attack.
