Benefits and harms of walnuts, properties, how to use


Walnut (Juglans regia) – the most popular tree of the genus Juglans, belonging to the Walnut family (Juglandaceae).

Other names are Greek nut, royal nut, Voloshsky nut.

It grows to a height of up to 25 meters, and is overgrown with a luxurious 20-meter crown, consisting of well-developed branches spread widely from the gray trunk. The leaves are large, complex, ovoid green “canvases”, up to 20 cm long and 10 cm wide. The flowers are colored greenish and appear on the branches along with the blossoming of the leaves.

The most valuable fruits in folk medicine are the fruits of the tree, spherical or egg-shaped, which during development are covered with a dense light green peel. As it ripens (late summer, autumn), the peel bursts, and under it there is a woody “pit”. Inside the shell, separated by 2-5 partitions, there are edible kernels, also called nuts.

The natural habitat of growth is the territory of almost all of Eurasia, but the tree bears fruit well only in countries where there is a combination of heat and moisture (Ukraine, the Caucasus, the Balkans, Kyrgyzstan, Northern India and China, Greece, etc.). In severe frosts, the plant not only grows poorly, but also practically does not bear fruit.

Many people know about the healing properties of the walnut, or mahogany, Voloshsky, royal, Greek nut, as it is also called, but few have heard of the harm the leaves, flowers and fruits of the walnut can cause to the human body.

Leaves and leafy young shoots with walnut flowers are widely used in official medicine of foreign countries as an anti-inflammatory, wound-healing, antimicrobial agent in the form of granules, drops, ointments, tinctures, suppositories and other dosage forms.

If before the birth of the baby a woman was allergic to nuts, it is better to completely avoid them during the period of breastfeeding, as the risk of allergies in the baby increases.

How to choose the right nuts when buying? It is better to buy nuts unshelled and in shell. The shell must be clean, without damage or cracks. Shake the nuts; if they rattle, they are most likely old and dry. Peeled nut kernels must be full-bodied and undamaged. Wrinkled and dull kernels have probably lost their beneficial qualities. A spoiled nut will give off an unpleasant bitter taste. The freshness of the nuts is indicated by the brown or golden color of the fruit and the natural, pleasant aroma. It is not recommended to buy shelled walnuts, since it is not known for sure how long they last and under what conditions they were stored. It is known that shelled walnuts are not recommended to be left in the light; oxidation occurs in them. You should not eat moldy walnuts, as such nuts can cause poisoning.

If you decide to prepare a tincture of young walnuts and use it for treatment, be sure to consult with your doctor to rule out possible complications and side effects. This is especially important if you are going to give the tincture to children.

About the healing properties and nutritional value of walnuts

Yes, this fruit of a tree widespread in the North Caucasus is one of my true favorites. My family has long been accustomed to the fact that instead of regular sunflower oil, I add walnut oil to salads, in the morning I drink a teaspoon of black tincture from the green fruits of the plant, and for any bruises or joint pains, I give friends and acquaintances for rubbing the “fragrant” Todikamp, ​​the main component which is a walnut.. And now I also made soap with walnut juice, completely ruining the juicer with the brown liquid! You see, walnuts fight infections well and especially fungi, which is essential for daily hygiene. I made some soap and then started making jam, because that short period when the nut is in the stage of milky ripeness cannot be missed. In the fall, when the walnut reaches the stage of full ripeness, there will be a different song: it’s so nice to just dip the walnut kernels slightly calcined in the oven into aromatic honey; for my taste, chestnut honey is ideal for such a dessert, and wash it down with herbal tea. When eating such a dessert, you definitely need to think about the great benefits of those products, then they will fully have not only a nutritional, but also a healing effect on the body.

Many people believe that it was a walnut

to the territory of ancient Rus' from Greece itself. That may be true. But still, this plant is not found in the wild on its territory. It comes from Asia Minor. The internal contents of the nut itself are very similar to the brain with its division into the left and right hemispheres and numerous convolutions. This has given rise to the belief that nuts can stimulate the thought process and generally improve mental abilities. Of course, it is not the shape of the nucleus that influences the improvement of brain function, but its chemical composition.

The nut contains a lot of vegetable fat. It makes up approximately three-quarters or slightly less of the total mass of the kernel. It contains a huge amount of minerals and vitamins. Most of all it contains B vitamins, as well as vitamins E, P, C and K. There is a lot of organic magnesium, phosphorus, calcium and potassium. Up to 20% of the nut is protein, which contains in its structure the amino acids necessary for the human body. But not enough carbohydrates. And if it were not for such a high concentration of fat, walnuts would be considered one of the most excellent and indispensable foods for diabetics. It already surpasses almost three times in its nutritional qualities the most important and respected product of the Slavs - bread. In addition, scientists note the superiority of walnut fruits over cow's milk by ten times, over potatoes by 7 times, over apples by more than 12 times. And these are the most common products in our diet. Moreover, the valuable qualities of the nut are 50 times higher than the qualities of citrus fruits. Linolenic acid was found in the composition, which has the ability to lower the concentration of bad cholesterol in the blood, which is extremely effective for patients with atherosclerosis.

Walnut leaves

can act as
medicinal raw materials . They contain the dye juglone , which is deadly to many types of bacteria, especially fungal pathogens. Another element, the alkaloid juglandine, has the same effect. The leaves also contain essential oils, mineral salts, vitamins and flavonoids. A decoction of them is an excellent anti-inflammatory agent and is widely used as a strong antiparasitic agent , i.e. promotes the removal of worms from the body. It was popularly used as a tonic for diarrhea, to treat pain in the stomach area and for colic in the abdomen.
This remedy relieves gouty pain, supports (although does not cure) the fight against tuberculosis (a complete cure requires a complex of targeted remedies), promotes the regularity of menstruation and reduces the pain that arises in connection with them. But the beneficial properties of walnuts are not limited to this. Recently, it has been discovered that the leaves and partitions of the nut act on the body's cells, increasing their ability to absorb glucose. This helps reduce the concentration of this same glucose in the blood and is very important (especially) for patients with type 2 diabetes.

The recipe for making the decoction is very simple. For one tablespoon of crushed walnut leaves or , 200 ml of boiling water is enough. Pour in and leave for about half an hour. You can take about a quarter glass before meals 3 times a day.

Walnut oil and alcohol extracts prepared from milky ripe fruits also have antiparasitic and antifungal effects Nut oil is obtained exclusively in factory conditions, but alcohol tincture

You can easily prepare it at home.

Green walnut tincture recipe

is as follows: 40 nuts of milky ripeness should be cut in half and filled with 3 liters of 40% alcohol, left for a month. Use 1 teaspoon orally 3 times a day before meals (dilute with water) and as an active ingredient for preparing ointments.

The walnut tree lives a long time and a hundred years is not the limit for it. Every year, some branches of the tree die off and become dry, but young and flexible branches appear in their place. Like a snake, it seems to shed its old skin. One such “ancient” specimen grows with a neighbor right behind my house. I love photographing young nuts against the sky. You just need to help the tree by removing old dry branches. You can grow it from the nut itself. However, you need to remember that the tree prefers a warm southern climate. The first fruits appear on it ten years after planting.

Walnuts grow a lot not only in the Caucasus, but also in Ukraine. This is a great, very useful , natural and most importantly – affordable medicine!
