part of this berry.

Bilberry fruit contains one of the richest sources of anthocyanosides (anthocyanidins).
These may strengthen the capillary walls. This effect may protect blood vessels and
reduce extra fluid in your body. These are also natural antioxidants.
Bilberry may prevent or slow the progress of macular degeneration. This condition
causes your central vision to get worse. Bilberry has been used to help night blindness.
Bilberry may have a diuretic effect. It increases how much urine you make and how
much leaves the body. It may be a urinary tract antiseptic and help with inflammation.
Bilberry is also claimed to help control low blood sugar (hypoglycemia). It does this
by improving your insulin level.
It may ease stress and anxiety, and heal gastrointestinal ulcers. Bilberry may lower
blood lipids and strengthen connective tissue. Some claims suggest that bilberry may
slow the progression of cataracts.
