The Big Coconut: Blueberries

 

Blueberries were prominent in Russian folk medicine, used as a preventative measure and cure for flux and other abdominal problems.

Native Americans used blueberry leaves in medicinal teas thought to be good for the blood and blueberry juice was used to treat coughs.

The blueberry is still prized for its antioxidant health benefits and as a laxative, as well as other folk remedies.
During World War II, British Royal Air Force pilots consumed bilberries (a blueberry relative), which purportedly improved their night vision. Later studies show a sound basis for this practice because blueberries are high in bioflavonoids which are used by the rods in the eye for night vision.

Blueberries rank as the number one fruit provider of antioxidants. They are also high in iron.

Especially in wild species, blueberries contain anthocyanins, other antioxidant pigments and various phytochemicals possibly having a role in reducing risks of some diseases, including inflammation and certain cancers.
