What's the Buzz with ATTTA #68

Thursday, 7 October 2021

Over the past month of the blog, we have been discussing various topics related to fall beekeeping: feeders & feeding, varroa mite monitoring & management, and new findings concerning nosema. In addition to these parts of fall beekeeping, many beekeepers are also working in honey houses to extract this year’s honey crop. Honey has both a long and broad standing history of uses. From ancient mummification to a culinary sweetener to medical treatments, there is no doubting the versatility and usefulness of this bee-made liquid gold that beekeepers across the Maritimes are busy harvesting.

What’s the Buzz with ATTTA Podcast Episode 9 is now available for your listening enjoyment! Keep following below for a sneak peak of topics discussed in conversation with Dr. Sarah Wood, a veterinary pathologist whose research concentrates on honey bee health.

A Beekeeper’s Fall

The floral blooms have come and gone; the bees have finished their work for the year.  Beekeepers are busy harvesting the liquid treasure that has been accumulating and ripening in supers over the season. Across Atlantic Canada fall has begun to set in; the leaves are changing colors, geese are flying south, and the air is getting crisper. But inside the honey house the air is warm and sweet, and the frames of honey glow gold, ready to fill jars and remind us of summer sunshine through the cold of winter.

This year we saw abundant floral blooms on the landscape throughout the beekeeping season thanks to the early onset of spring and a good amount of rain.  However, this may not always translate in honey harvest numbers since there are so many other factors that also help determine the total honey yield for a particular season. For example, although the rainy days promote plant growth and contribute to a greater abundance of flowers on the landscape, they are stay-at-home, no-forage days for bees. This reminds us that everything is a balance and there is always more to learn. To all the Atlantic honey producers, we wish you a great honey harvest this year!

 

Recent advances in honey-based hydrogels for wound healing applications: Towards natural therapeutics *

Aside from its delicious sweetness and aesthetic golden glow, honey has been used for many purposes for many years. Honey has a great potential for uses in medical treatment settings, however, the medical value of a particular honey is largely dependent on the substances present in the honey from the surrounding environment. A recent review highlighted some recent advancements in using honey in medical settings, especially for use in hydrogels for wound care. A hydrogel wound covering acts as a flexible skin-like barrier that keeps the wound moist while promoting healing. Adding honey as an ingredient in these hydrogel wound coverings adds even more medically beneficial properties, such as:

  • Antibacterial – reduces production of excess wound fluids (i.e., pus)
  • Anti-inflammatory – reduces elevated inflammation of chronic wounds
  • Hydrating – provides a moist environment & allows for more efficient wound management
  • Hydrophilic – absorbs body fluid to maintain humidity appropriate for wound healing

As-is, honey can be a bit of a difficult substance to use practically and precisely as a tool, especially in a medical setting. These advancements of using honey in wound care, as an ingredient in hydrogel coverings, help in developing a reliable and practical delivery method to incorporate these healing properties of honey into medical treatments.
