Vikings have been using honey for over a millennium, and the bee elixir's known antiseptic and antibiotic properties are now scientifically proven.
Honey's high sugar content has been shown to dry wounds in order to facilitate healing. Honey's acidity has also been found to impede bacterial growth. In addition, an enzyme used by bees to process flower nectar produces oxygen peroxide when combined with sugar and water, with lethal effect on bacteria. Honey further contains an unknown active ingredient, still the subject of much research, directly linked to the eradication of otherwise antibiotic-resistant bacteria, such as Staphylococcus aureus.
In practical terms, namely clinical trials by Dr. Sebastian Zaat, 1 to 2ml of honey was found to be particularly efficient at killing 10ml of any possible type of bacteria. An feat no actual man-made antibiotics could ever achieve.
There is, after all, a reason why honey is used as an ingredient in every single products handcrafted by Sönnungr Viking Co. It just is good for you!
