The genus Vaccinium belongs to the health family, and members include the blueberries (bilberries), cranberries, and whortleberries. Total world production is estimated to about 1 million tons per year. These widespread, small fruits are found nearly everywhere in the Northern Hemisphere.

Knowledge of the chemical composition of the plant part of Vaccinium spp. is relevant because some phytochemicals (from the Greek phyton, plant) have biological activity, and berries are used as food and as medicine.

Salvation For The Sleep Deprived The Ultimate Guide To Sleeping, Napping, Resting And  Restoring Your Energy. Of the many things that we do just instinctively and do not give much  of a thought to, sleep is probably the most prominent one. Most of us sleep only because we have to. We sleep because we cannot stay awake all 24 hours in the day.
