The deal with raw, unfiltered honey is it can have small bits of wax, dirt, or other impurities in it. If you put it through a sieve, you can filter out the wax and other particles.
Honey does have natural anti-microbial features.
Honey has been used for centuries as a salve for open wounds to keep major infection at bay.
At our rescue, we have used hydrotherapy and honey treatments on open wounds for many years and it is highly effective. All under vet's orders.
But when it comes to feeding honey, we prefer the filtered kind so the gliders are not ingesting wax or other foreign particles.
At the store:
Raw, unfiltered honey is typically labeled as such
Filtered honey is either labeled as "filtered" or has no labeling
Local honey is typically advertised as being local honey.
Pasteurized honey will have a label that says so.
