The chemical composition of the plant contains vitamins and minerals important for the body, organic acids and other substances. Moreover, both berries and currant leaves benefit.
The benefits of berries
Berries contain vitamin C, which is necessary for strengthening immunity, which is involved in the process of antibody production. To maintain the body's defenses, the fruits are consumed fresh and processed . Moreover, when drying, freezing or preserving raw materials, only an insignificant part of the vitamin is lost, which does not detract from the useful qualities of the product.

Potassium and vitamin K contribute to the improvement of blood composition, normalize its coagulation, strengthen the walls of blood vessels . Vitamin K has the ability to remove toxins, poisons and breakdown products of drugs from the body, cleansing the kidneys and liver. The substance plays an important role in the health of bone, muscle, cartilage and connective tissue.

The use of culture in cooking and cosmetology
Whitecurrant in cooking is a popular ingredient in many dishes. Berry is used as a filling for pies, and fruit fudge is prepared for cookies and muffins. Delicious desserts are made from currant puree:
- fruit soup;
- ice cream;
The berry is also suitable for non-sweet dishes. Sweet and sour sauce for meat and poultry is prepared from grated fruits. Berries are added to vegetable salads.
White berry in cosmetology is no less demanded. The advantage of these fruits in the absence of coloring pigments, which makes it possible to use before leaving home. In addition, unlike their colored relatives, the culture does not cause an allergic reaction .
The presence of organic acids, tocopherol, retinol and vitamin C makes the berry an indispensable tool in the struggle for beauty and youth. Essential substances extracted from inflorescences and foliage of currant are used as a perfume for perfumes in cosmetics: shampoo, milk, soap.
- So, currant-based cosmetics have the following effect:
- Increase skin elasticity.
- Tighten the contour of the face.
- Normalize the work of the sebaceous glands, reducing pore sweating.
- They help smooth out facial wrinkles.
- Eliminate swelling and bruising under the eyes.
- Activate the process of regeneration of skin cells, slowing down aging.
Contraindications and health hazards
Culture does not have a large list of contraindications; rather, these are warnings for special health conditions.
Important! It is not recommended to give the product to children under 8 months of age: their enzymatic system is not yet sufficiently developed and is not able to protect the children's stomach from acid.
- It is not advisable to use the product in such situations:
- just suffered a stroke;
- increased acidity in the stomach;
- acute form of gastritis or gastrointestinal ulcer.
Even to a healthy person, a product can be harmful if consumed in large quantities. Ascorbic acid irritates the gastric mucosa, and large amounts of fiber can cause constipation. An adult without damage to health will be enough to eat 200-300 g of berries per day.
Cultivation and care of white currants
The culture site should be well lit. Groundwater location - 2 m below the soil surface. Currants grow well on fertile, loose soil, with a neutral or slightly acidic reaction.
We recommend reading where to plant currants - in the shade or in the sun.
Planting can be carried out both in the spring (April), and in the fall (September). The place is prepared a week before the procedure:
- They clear the soil of plant debris.
- The landing hole is dug out with dimensions of 50 cm in diameter and 40 cm in depth.
- The distance between several seedlings is left at 1.5 m.
- Fertilizers are added to half the soil extracted from the pit - 6-7 kg of humus, 20 g each of superphosphate and potassium sulfate.
- At the bottom, a hill 30 cm high is formed from a nutrient earth mixture.
- The seedling is placed in a pit under a slight slope, deepening the root system by 10-12 cm.
- Sprinkling the plant with soil, they tamp well, driving out voids.
- After conducting watering, spending 5 liters per bush.
- The final stage is trimming the top. There are 5 buds on the seedling.
It is convenient to irrigate the soil in grooves made in the near-stem circle at a distance of 30–40 cm from the trunk of the plant. The culture does not like waterlogging, so watering is carried out no more than once a week . The exception is the dry period: if the land is too dry, the interval between irrigation is reduced. For an adult bush, 10 liters of water at a time is enough.
After watering, you need to loosen the soil and weed the weeds. To retain moisture and protect the roots from overheating, a layer of mulch from peat or sawdust is applied on top.
Overfeeding currants is not recommended: this may affect the quality of the crop.
Important! With an excess of nutrients, the bush will begin to “fatten”, increasing green mass. The berries will be acidic and small.
- April - application of urea 15 g / m² or infusion of mullein diluted with water 1:10 to the soil;
- end of May - 15 g of urea, 30 g of potassium sulfate and superphosphate per 10 l of water are added by the root method;
- the end of June - according to the sheet, with a solution of zinc sulfate, boric acid and vitriol, 2 g each, plus 5 g manganese sulfate per 10 l of water;
- end of September - introduction of 10 kg of compost, 30 g of potassium sulfate and 80 g of superphosphate into the near-stem circle.
Currants can be propagated vegetatively and seeds. The seed method is a painstaking and long procedure, so it is more used by breeders. Gardeners prefer to propagate the crop vegetatively.
Did you know? Currant berries are useful for people working with radioactive materials and affected by radiation sickness. The product removes radioisotopes from the body.
- In the spring, before the buds wake up, several shoots 1-2 years old are selected on the mother bush.
- They are bent to the ground and laid in dug grooves with a depth of 10 cm. They are pinned with metal staples and sprinkled with soil. The top of the branch, about 2 cm, remains above the ground.
- When the tip extends 10 cm, it is spudded to half the length of the trunk.
- After 3 weeks, the procedure is repeated.
- In the fall, layering has already taken root and can be transplanted to a permanent place. He will begin to bear fruit in 2-3 years.
Propagation by cuttings:
- Cuttings are harvested in February from semi-lignified shoots growing inside the crown.
- Cut at an acute angle, 20 cm long. Each segment should have a minimum of 5 kidneys.
- Apical shoots are not suitable for cuttings, - they take the middle of the branch, about 8 mm thick.
- Cuttings are placed in water to form roots.
- In spring, shoots are planted in the ground under the shelter of a greenhouse. Small roots should develop well.
- Shelter is removed after 3-4 weeks.
- Future seedlings spend 2 years on a temporary bed, then they are moved to a permanent place.
Diseases and pests of white currant
Currants in the absence of prevention can be attacked by insects and be affected by diseases. The main adversities and methods of dealing with them:
- Anthracnose, septoria, powdery mildew . The broad-spectrum biological product Alirin B destroys most fungi. It can be used at all stages of plant development. Working solution - 2 tablets per 10 liters of water, spraying.
- Mosaic, rust . An effective drug in the fight against bacterial and fungal infections is Bordeaux liquid 3%. Spraying is carried out before budding, in dry weather.
- Aphid, spider mite . Insecticide "Akarin" is used against gnawing and sucking pests. Working solution from aphids - 6 ml per 1 liter of water, from a tick - 2 ml per 1 liter of water.
- Flame, glass . Apply a solution of the drug "Inta-Vir" in the proportion of 1 tablet per 10 liters of water. Processing is carried out before flowering and after harvesting.
Preventive treatments with a Bordeaux mixture of 1% are carried out in the spring before flowering, twice, with an interval of 2 weeks. The product effectively protects against diseases and insect attacks.
Agrotechnical measures to prevent problems:
- sanitary pruning;
- harvesting after fruiting.

Harvesting and storage of crops
You need to harvest in dry weather, otherwise the berries will not be stored for a long time. Break off with brushes, laying in baskets or wooden boxes. The capacity of the container is desirable no more than 3-4 kg, so that the lower fruits are not crushed under the weight of the upper ones.
So, the benefits of white currant are invaluable for both children and adults. Berry can also be consumed by those on a strict diet: its calorie content is only 42 kcal per 100 g. And knowledge of the rules of agricultural technology will help to avoid mistakes when growing.
