Bilberry Health Benefits
The bilberry fruits contain different organic acids that stimulate action in the digestive system. It also includes sugars, tannins, pectin, myrtillin, anthocyanins, vitamins A and C, and B in a lesser amount.

Besides their nourishing and refreshing properties, they have astringent, antidiarrheic, antiseptic, and vermifuge effects. Health experts recommend them in the following cases:
1. Circulatory conditions of the venous system: swollen legs, varicose veins, phlebitis, varicose ulceration, and hemorrhoids. The many bilberry health benefits result from the anthocyanins that it contains, which protect and reinforce the wall of the capillary and venous vessels; hence, they prevent the flow of proteins and liquid to the tissues, thus reducing edema and congestion. Taking a bilberry supplement also works on the heart, increasing the resistance of the heart muscle.
2. The weakening of the retina and loss of vision: The main medicinal property responsible for bilberry leaf benefits is anthocyanins, which act on the retina capillaries, improving the irrigation of the light-sensitive cells. They are useful to recover night vision acuteness and to improve visual adaptation to darkness.
Bilberry dosage is also recommended for diabetic retinopathy, short-sightedness, and degeneration of the retina caused by high blood pressure arteriosclerosis or other reasons like retinitis pigmentosa.
3. The bilberry plant is also beneficial for those suffering from diarrhea, especially if the diarrhea is caused by a disturbance to the intestinal flora. Also, bilberries can stop flatulence caused by intestinal fermentation thanks to the plant’s antiseptic effect. Bilberry also helps to reduce inflammation and normalize the intestine functions, especially those of the colon.

According to experiments, both the leaves and the fruits of the bilberry plant prevent excessive Coli bacteria growth, which produces intestinal flora issues and urinary infections.
4. Intestinal parasitosis, especially the one caused by oxyuridae, which are small parasite worms that usually live in the intestine of small children. Therefore, health experts recommend a remedy with fresh or cooked bilberries in puree over three days.
The patient should only drink milk and bilberries. According to Dr. Schneider, the success of this treatment has been proven in the Children’s Hospital of the University of Helsinki (Finland).

5. Urinary infections: The juice of fresh bilberries, or their extract, exerts an antiseptic action on urinary organs, such as the urinary bladder or the urethra. For recurrent cystitis, which is frequent in some women, continuous intake of bilberries is recommended to avoid this ailment for one to three months.
6. Bilberry benefits for skin afflictions, such as eczema, folliculitis, and varicose ulceration. In such cases, bilberries’ juice is locally applied in fresh or concentrated lotion, utilizing a decoction.
Bilberry leaf benefits deserve mention. They contain tannin, flavonoid glycosides, and glucose-quinine, a substance that reduces the amount of glucose in the blood. So, they have the same astringent and antidiarrheic effects as the fruits, and they are also hypoglycemic. Thus, they are helpful for diabetic people since bilberry leaves reduce their insulin or oral medicines dosage.
