Blueberries have anti-cancer and antibacterial properties. they are
good for the health of the eyes, intestines,
circulatory system and urinary tract.
The properties of blueberry
Blueberries are part of the Vaccinium species, which also includes
cranberries and bilberries. They are small, purple berries that are
commonly found in western and central Europe, Canada and North
America. Thought to have been used in European folk medicine since
the 16th century, blueberries have excellent antioxidant properties
which make them useful for preventing cancer and other degenerative
diseases. In fact, when compared to other fruits, blueberries are
among the top sources of antioxidants.
Blueberries have a powerful antibacterial action in the intestine –
especially upon coli bacteria – they promote the healing of gastric
ulcers, and the leaves of the blueberry plant contain tannin, which
has strong anti-diarrhoeal properties.
Blood circulation is enhanced by substances found in blueberries,
such as vitamins A and C, bioflavonoids, anthocyanosides,
glycosides and delphininol. Blueberries may help to lower blood
sugar, decrease the chances of blood clots forming and enhance the
health of blood capillaries.
Blueberries can improve eye health and sight. This is thought to be
due to compounds in the berries that enhance the health of
capillaries in the eye.
Cranberries (Vaccinium oxycoccos) are a close relative of
blueberries and are native to North America. They are a well-known
and popular treatment for urinary-tract infections, such as
cystitis (an inflammation of the bladder resulting in frequent,
urgent and often painful urination). Drinking the fresh juice of
either blueberries or cranberries can help to prevent urinary tract
infections.
Blueberries in the diet
Since blueberries are excellent antioxidants, they are important in
the diet to promote long-term health and to prevent age-related
physical changes and chronic diseases. In particular, people with
cardiovascular problems, mild diabetes, eye problems, urinary tract
or intestinal infections should eat blueberries regularly.
Blueberries make wonderful pies, syrups and jam and are much
enjoyed by children. They can be made into liqueurs or preserves
for adults or the berries can be added to fruit salad or simply
eaten as a snack on their own.
Medicinal preparations
In addition to eating blueberries, the berries and leaves can be
made into medicinal preparations. Blueberry decoction is useful for
diarrhoea, colitis and poor night vision. It can be used as a
mouthwash for sore throats and ulcers, and as a face wash for
eczema. To make, boil 75 g blueberries in 1 litre of water until
the volume of water has halved. Strain and use as
appropriate.
Blueberry and strawberry leaf decoction is good for mild diabetes,
intestinal problems, arteriosclerosis, rheumatism and arthritis and
it can be drunk throughout the day. Boil 20 g each of blueberry and
strawberry leaves in 1 litre of water for 3 minutes. Then leave to
infuse for 10 minutes, strain and drink.
To make a tincture of blueberries, add 100 g fresh blueberries, a
handful of blueberry leaves and the zest of one lemon to 700 ml
vodka. Leave in a cool, dark place for 3 weeks and then press and
strain the mixture and store in a tightly sealed bottle. Take 20–30
drops of this tincture a day for diarrhoea, intestinal
problems,
