Yes, a "pure honey" label signifies that the product is indeed 100% honey, containing no added ingredients.
Pure honey, by definition, consists solely of honey derived from the nectar of plants, processed by bees. The "pure" label assures consumers that the honey hasn't been diluted or adulterated with substances like corn syrup, sugar, or other additives, which are sometimes used to lower production costs in commercially produced honey. Therefore, when you buy pure honey, you are getting only honey.
