Approximately 85% of blueberries consist of water, but the remaining 15% represent an amazing balance of vitamins and other useful elements necessary for the human body.

If you live in the growing regions of this useful berry, blueberries, of course, are best consumed fresh. But the main medicinal properties of fruits and leaves, as already mentioned, are beginning to manifest when the product is consumed by the course, on a regular basis, therefore, it is impossible to do without preparing raw materials.
Homemaking for the winter make many housewives seeking to take care of their family. But it is important to know how to properly prepare apples, cherries, yoshtu, squash, green garlic, pumpkin, so as to preserve the natural seasonal vitamins.
Drying
For therapeutic raw materials, the collection of blueberry leaves should be carried out in early summer, when the shrub is in bloom. Later leaves somewhat change their chemical composition, as a result, certain useful properties in them are preserved, while others are completely or partially lost. As a general rule, after the appearance of the berries, fruits should be collected, not leaves. 
Collected leaves are separated from the stem and dry away from the sun's rays, stirring occasionally. The shelf life of such raw materials - until the next harvest.
Did you know? Drying is a great way to harvest blueberries, because it allows you to almost completely retain all the healing properties of this useful berry.In order to properly dry blueberries, you must follow these rules:
- for harvesting, you should choose a dry and sunny day and do it in the morning, as soon as the dew dries on the berries;
- collected berries should be picked as quickly as possible, getting rid of rotten, overripe, crushed or damaged fruits;
- each berry should be free from the stalk before drying;
- Then the berries are quickly washed under running water, thrown into a colander, allowed to drain, sprinkled evenly on gauze, paper or regular towels and allowed to dry completely.
Frost
Frozen blueberries are almost as healthy as fresh.
Did you know? As a result of long storage in the freezer, ascorbic acid contained in blueberries disintegrates, but all other useful properties are practically not affected.Berries are prepared for this type of harvesting as well as for drying. After complete drying, the washed and enumerated fruits are placed in one layer on a plane and placed in a freezer for at least a day. Then they can be poured into special containers for storing frozen food and returned to the freezer for permanent storage.
If you immediately pour fresh blueberries in a container for freezing, the berries stick together in a single room, and it will only need to be thawed whole, which is inconvenient, unaesthetic and wrong.The benefits of frozen blueberries in winter are simply indisputable, because at this time our body especially needs vitamins. The only condition: in no case do not freeze the berry again - after the first defrost, blueberries must be used. Another tip: be sure to keep frozen berries in a tightly closed container and avoid contact with other “inhabitants” of your freezer, especially meat, fish and other animal products.
Rubbed with sugar
To save the blueberries for the winter, you can also grind it with sugar. This method is more preferable than, say, jam or compote, because the product is not subjected to heat treatment, but still less successful than drying and freezing, of course, if we are talking about the use of berries for medicinal purposes.
In particular, in case of diabetes mellitus and for losing weight, such a product cannot be precisely used, although otherwise this preparation is quite capable of saving most of the beneficial properties of the berry. 
Enumerated and prepared berries should be chopped: if you have time and patience, rub through a sieve, if you want to speed up the process, smash with an immersion blender or skip through a meat grinder (of course, in this case the effect will be much worse than after a sieve).
Then mashed potatoes mixed with sugar in the ratio of 1: 1.5, mixed and left for a couple of hours. After a while, we lay out a ready-made treat for sterile jars, from the top we fall asleep with an additional layer of sugar, cork tightly and store in a cellar or in a refrigerator.
Important! Sugar in this recipe plays the role of a preservative, so putting it should be not less than the specified amount, otherwise the product will ferment or mold.
The use of blueberries in traditional medicine: the treatment of diseases

In addition, with gastritis, you can also take 10 drops of alcoholic blueberry tincture several times a day. For its preparation for a bottle of vodka you need to take 100 grams of fresh berry puree and insist for three weeks.

You can also prepare a particularly refined medicine: blueberries are mixed with a small amount of water, put on the fire and languish over low heat for 20 minutes. Then a glass of dry red wine is poured into the mixture, everything languishes for another 20 minutes, filtered and drunk a tablespoon three times a day.
Berries can be used dry or fresh, but in the latter case you can take less water (3 tablespoons of dry berries will need 100-150 ml of water).

In winter, dried or frozen fruits can be used. Regular consumption of the product stabilizes the kidneys and reduces the painful manifestations of the disease.

With eczema, skin inflammation, lichen, burns
For the treatment of skin diseases, blueberries can be used as an external agent.
Dried blueberries are poured with water in a ratio of 1: 5 and boiled until half the liquid boils away. The resulting mixture is spread on a gauze and used as a compress on the affected skin. 
Such a bandage should be changed several times a day, gently soaking dried gauze with warm water or milk whey.
Instead of decoction for a compress, you can use freshly squeezed blueberry juice or mashed potatoes made from fresh berries.
For rinsing for sore throat and gum disease
The oral cavity is rinsed with a decoction of blueberries (fruits are poured with five parts of water and languish until half the liquid is evaporated, then the broth is filtered).
How blueberries are used in cosmetology
As mentioned earlier, blueberries are a natural antioxidant and antiseptic, so that it is used not only in traditional medicine, but also in cosmetology, in particular, for skin care.
Regular decoction of blueberry leaves - a great cleanser to reduce the appearance of acne and other problems on the skin of the face.If you freeze the same broth and wipe the face with ice cubes, this will add a tonic effect and reduce puffiness and dark circles under the eyes.
Important! When taking care of your face, you should use leaves, not blueberries, otherwise, instead of rejuvenation, you will get dark spots from the juice on the skin.For the preparation of a nourishing mask fresh bilberry leaves are interrupted with a blender, we add a spoonful of kefir or sour cream and apply on cleansed face skin. After 20 minutes, wash off the mask with warm water.
You can make a similar mask from dried leaves, but first you need to steam it with boiling water to “wake up” the beneficial substances, and apply the already obtained slurry to the face. In addition to the milk supplement, you can dilute the leaves with any kind of cosmetic clay, and for dry skin, a mixture of blueberry leaves with beaten egg white is suitable.Contraindications and possible harm
The only direct contraindication to fresh consumption of bilberry is oxalaturia. This is a specific disease characterized by a sharply acidic reaction of urine due to the presence of salts of oxalic acid and calcium in it. Pancreatitis and other diseases of the pancreas - a reason to consult a doctor before eating blueberries, or eating it in limited quantities.
The rest of the berry will not harm your health, unless you use it without measure (a side effect in this case is expressed in the binding effect of blueberries on the gastrointestinal tract). Another caveat concerns an allergic reaction, which is rare for blueberries, but is still possible. 
Considering the blueberry in terms of the ratio of benefit and harm, there is no doubt that the first outweighs. Observe the measure, be attentive to your body, listen to the signals that it sends you and enjoy the wonderful taste and aroma of berries or herbal teas, which, if you do not heal all your ailments, you will definitely restore strength and good spirits!
