This compound is naturally present in various vegetables, and we can also obtain it through supplements. It is effective against allergic symptoms.
WHAT IS QUERCETIN AND WHAT FOODS IS IT IN?
Quercetin is a very effective bioflavonoid to reduce inflammatory processes and control allergies.
The body cannot produce it, so it must be obtained from the diet or with supplements.
It is a natural greenish-yellow pigment present in vegetables such as:
- Red cabbage
WHAT ARE THE BENEFITS OF QUERCETIN?
The antihistaminic activity of quercetin help control symptoms of allergy (swelling, sneezing, itching, runny nose and watery eyes) and prevents damage to the overproduction of inflammatory mediators, such as histamine and leukotrienes, it occurs in the vascular endothelium.
It also prevents lipid peroxidation (oxidation of fatty acids that deteriorates cell membranes) and increases the concentration of glutathione (an antioxidant that the body produces internally) in the intestinal mucosa. Both actions that help repair the fragile wall of the intestine, balance its permeability and stop the passage of allergens into the blood.
Additionally, quercetin inhibits the RNA replication of the viral genomes of herpes and other viruses, thereby helping to control infections.
It also improves the contractile function of the left ventricle, protects the coronary arteries and prevents the formation of intravascular thrombi.
THERAPEUTIC APPLICATIONS OF QUERCETIN
The great antioxidant, anti-inflammatory and antiviral power of quercetin makes it one of the main flavonoids in the prevention and treatment of multiple pathologies such as:
- Food and environmental allergies.
- Arthritis and inflammations.
- Early aging
- Viral infections such as herpes.
- Complications of diabetes, such as retinopathies.
- Neoplasms: slows the growth of cancer cells and increases their apoptosis (cell death, in this case of malignant cells).
- Intestinal permeability.
- Circulatory problems: arteriosclerosis, varicose veins, hemorrhoids, etc.
HOW QUERCETIN IS TAKEN IN ALLERGY
Quercetin is sold in capsules, alone or in combination with another bioflavonoid. Since bioflavonoids favor the synthesis of vitamin C and prevent its oxidation, it is also common to find it together with this vitamin.
A dose of 600 to 1,000 mg daily for the first few weeks of an allergic reaction helps reduce symptoms within a few days.
As prevention or maintenance, 300 or 500 mg daily are enough, depending on the pathology and severity of the symptoms.
