Honey is essentially bee vomit. Honey bees collect the nectar of flowering plans, and through a process of regurgitation and evaporation, the nectar eventually becomes concentrated into honey which they use as food.
When you buy honey in most supermarkets it has usually been filtered and pasteurized for cosmetic reasons, as well as to lengthen its shelf life. Raw honey is unpasteurized and minimally filtered, leaving it thick, cloudy, and slightly granulated. Raw honey contains living organisms such as yeast.
Honey has been collected from the wild and cultivated domestically for thousands of years. Its the main ingredient in Mead, one of the world's most ancient alcoholic beverages. It has also been used medicinally for much of that time, though there is little scientific evidence to back claims by modern organic foodies who insist that, when consumed raw, honey is a powerful super food and cure-all that helps to manage everything from weight to cancer.
It would be great if there really were 'super foods' that magically cured all of our ills. Unfortunately its a bullshit concept. True health is obtained and maintained over many years of 'healthy living-' and overall approach, and not any single element in isolation. Maybe a little raw honey should be part of our overall plan for health... i don't know.
What I do know is that this stuff tastes fantastic.
