We never use any chemical treatments on our bees.
Our honey is "Raw Honey" (i.e., unheated, unfiltered, and unprocessed). We extract honey from the comb via a centrifuge extractor, then allow it to drip through a set of sieves to remove wax particles. Raw honey eventually crystallizes, with no effect other than color and texture. If desired, honey can be de-crystallized by gentle heat. Honey should be stored at room temperature, preferably away from sunlight. There is no need to store honey in the refrigerator.
