Properties of dog rose

The bud- derived of young shoots has immunomodulating properties, ie it regulates the body's immune response, giving the preparation an effective action against all forms of allergy. In particular, its intake improves the immune response at the respiratory level in those with an allergic tendency and in children.

The anti-inflammatory property finds an important therapeutic use in acute phlogosis which involves alterations of the nasal mucosa, of the eyes and of the first airways with consequent production of phlegm.

For these properties, the dog rose not only represents an excellent remedy in the prevention of allergies and in the treatment of rhinitis, conjunctivitis and asthma due to contact with pollen; but it is recommended in childhood diseases such as tonsillitis, nasopharyngitis, otitis, cough and cold of infectious origin.

The small fruits (berries) of the dog rose are considered the most concentrated " natural springs " in Vitamin C, present in quantities up to 50-100 times higher than oranges and lemons, and for this reason they can contribute to strengthening the natural defenses of the organism (100 grams of berries contain the same amount of vitamin C as 1 kilo of traditional citrus fruits).

The vitaminizing action is linked to the antioxidant action of bioflavonoids, contained in the pulp and peel, which act synergistically with Vitamin C, optimizing blood circulation.

This beneficial effect on the quality of the blood is due to its ability to promote the absorption of calcium and iron in the intestine, balancing the level of cholesterol and contributing to the production of hemoglobin; it also activates vitamin B9 (folic acid) with a slight antihistamine effect.

Since vitamin C, also known as ascorbic acid, cannot be synthesized directly by man (unlike what happens with other animals), it must be introduced either with food, if the diet is good and balanced, or with the food supplement, in cases where the diet is lacking, as normally happens.

The western lifestyle, industrial pollution, the influence of electronic devices and cigarette smoke are all factors that increase our needs, so supplementing with vitamin C is practically necessary.

In this sense, the rose hip is an excellent tonic to cope with exhaustion and fatigue, it helps to overcome stress; stimulates the elimination of toxins (especially uric acids, which cause gout and rheumatism) through diuresis.

The berries have an astringent action due to the presence of tannins, useful in case of diarrhea and intestinal colic.

The dog rose can also be used in the form of glycerine macerate for the care of our animal friends, and in particular to prevent the laryngitis of dogs and cats in the winter period.

Background

This plant owes the botanical name " canine " to Pliny the Elder, who reported of a Roman soldier, bitten by a dog and cured of rabies, thanks to the assumption of a decoction of roots.

Dog rose was already appreciated for its effectiveness in strengthening the body's defenses against infections and particularly against the common cold.

In the Middle Ages it was commonly used in traditional remedies for respiratory problems, and the fruits were very popular in desserts.

Its use has played an important role in the supply of Vitamin C to British children during the Second World War to replace the normal citrus source.

The procedure used in the eighteenth century to reduce fruits in purée as a form of taking the plant, has given way to the infusion of its dried berries.
