blueberryWe are reaching the peak of blueberry season in Downeast Maine this first week of August, yet few people know all the wonders of this beautiful plant. Blueberries are well known for being a common wild edible, but Ray also recommends their use for treating diabetes. Once people suffering from diabetes eliminate most carbohydrates from their diets, eating more blueberries can act as a delicious diabetes medicine. Including huckleberries (Gaylussacia baccata, Ericaceae) and juneberries (Amelanchier, Rosaceae) into this regimen is even more effective. Arthur Haines also speaks about a compound that blueberries contain which improves the health of the rods in our eyes, thus improving night vision. The whole blueberry plant—leaves included—are remarkably high in anthocyanins, making this plant a noteworthy antioxidant. At least one Maine farm is selling more than just the fruits of this plant: Blueberry Tea and Barque.

Blueberries and their flowers have traditionally been used in a variety of native foods, but have also have been used specifically for medicine. The Algonquin have used lowbush blueberries for a variety of women’s and children’s health problems. Women would take an infusion of the leaves after miscarriage and an infusion of the roots to induce labor. This leaf infusion was also given to children for treating colic. The Makah also used an infusion of the leaves of bog blueberry, Vaccinium uliginosum, for women after childbirth.
