Colonies foraging heavily on Camellia oleifera are reported to suffer digestive disturbance, brood loss and adult mortality.
Chinese research attributes the effect to oligosaccharides in the nectar that honey bees digest poorly, with Apis cerana affected less than Apis mellifera. The mechanism is not fully settled and the effect size varies between reports.
What this does not claim: This is not a claim that the honey is harmful to people. It is eaten regionally without recorded incident, and the problem described is one for the colony rather than for the consumer.
