And sometimes, this can be lifesaving. Honey produced from some rhododendron flowers contain significant levels of gryanotoxin - a fact used in ancient Greek warfare (perhaps an early bioweapon?). Contrasting the "health halo", in fact, some single source honeys are downright poisonous, and we will be hard pressed to police which flowers the bees harvest from. In places like Turkey where rhododendrons grow, the potential for widespread gryanotoxin poisoning is stopped by blending, since the toxin becomes diluted by other honey sources.
