Blueberry

Blueberry leaf refers to the evergreen European blueberry, or Vaccinium myrtillus, also known as huckleberry, whortleberry, trackleberry, wineberry, bilberry and, of course, blueberry. However, in official botanical lingo, bilberry is considered to be most accurate to avoid confusion with the numerous other species in the Vaccinium genus commonly called blueberry.

The physical structure of the plant is very distinctive in both appearance and texture, however, setting it apart from its botanical cousins. The leaves, which appear as dark green in summer and turn bright red in winter, feel like worn leather between the fingers. Another unique characteristic of this species is that it produces fruit singularly or in pairs, while the common blueberry plant bears clusters of berries.

In traditional medicine, blueberry leaf is used to treat inflammation associated with asthma, allergies, dermatitis, acne and joint disorders, as well as gastrointestinal complaints and kidney and urinary tract infections. The medicinal effects of blueberry leaf are attributed to a class of chemical compounds called anthocyanins, which possess potent antioxidant properties. The anti-inflammatory effects are due to the presence of phenolic acids, such as salicylic acid. Blueberry leaf also contains catechins, the same antioxidant agents found in black, green and white teas that have been shown to lower cholesterol and glucose levels.

Blueberry leaf tea, made from 1 teaspoon dried herb to a cup of boiling water, may be taken 2 to 3 times a day. Be aware that flavonoids in the leaf that lend the plant color may cause the urine to appear slightly reddish. Since blueberry leaf can cause a slight drop in blood sugar, check with your physician before using this herb if you have diabetes.
