In the study, Quercetin was found to have a variety of biological characteristic, including antioxidant, anti-inflammatory, anti-bacterial, anti-viral, free radical scavenging, and immunomodulatory activity, which form the basis of overall health and disease resistance. These substances are natural pigments that have evolved over hundreds of millions of years. In addition to giving fruits and vegetables a colorful appearance, they have the most important role in strengthening the immune system, which is the key to the survival of plants against foreign invaders.

Hasan ÖNAL, American medical doctor, to examine the role of Quercetin in COVID-19. Ninety five new patients received a therapeutic dose of 1,000 milligrams and 113 health care workers received a prophylactic dose of 500 milligrams. In both groups, no deaths were observed in the new coronary patients treated with Quercetin, and no confirmed cases were recorded in the health care workers treated with prophylactic quercetin. A team led by Maurizio Marvisi, an Italian respiratory specialist, performed two chest CT scans on 90 cured patients and found that 25% developed pulmonary fibrosis. The team warned that patients infected with new crown pneumonia were at risk of developing pulmonary fibrosis, which can lead to breathing difficulties. Smokers, the elderly and people with chronic diseases are at high risk of developing pulmonary fibrosis, the researchers said.

The Cnr-Nanotec Institute in Cosenza，Prov.di has found that Quercetin, the most common element in fruits and vegetables, can be used as a specific inhibitor of coronaviruses, the Republic reported. The research, carried out in collaboration with Spanish researchers, found that Quercetin could deliver a “Fatal”blow to the new coronavirus by blocking the enzymatic activity of the coronavirus endopeptidase C30. The research, published in the International Journal of Biomacromolecules, could lead to the development of new crown drugs. Quercetin is a kind of natural flavonoid found in nature. It has multiple biological activities, such as anti-oxidation, anti-allergy, anti-inflammation, anti-virus, etc. . It is abundant in common vegetables such as CAPER, red onion, chicory, tomato, and Broccoli.

The progress of a research project begun in March by the University of Zaragoza (Unizar) was announced recently, the project has identified a natural compound, Quercetin, that could be an effective drug against covid-19 or a new starting point for the development of a new drug. In the development of this study, the biophysical structure of 3CLpro virus enzyme was reported for the first time, and a natural product Quercetin was identified as an effective inhibitor of 3CLpro virus enzyme by the screening procedure of experimental compounds. Therefore, if the activity of Quercetin is demonstrated in living organisms, Quercetin may constitute a new crown drug, or it may be a new starting point for the synthesis of drugs with better performance. Quercetin is a widely distributed flavonol with many biological activities in the plant kingdom.
Scientific Studies Have Shown That Quercetin Has Important Medical Value
Quercetin can fight free radicals, complexing or trapping free radicals to prevent the body’s Lipid peroxidation reaction, can directly inhibit tumors, effectively play a role in cancer prevention and anticancer; In anti-bacteria, anti-inflammation, anti-allergy, prevention of diabetic complications also have strong biological activity. In addition, Quercetin can lower blood pressure, enhance capillary resistance, reduce capillary fragility, reduce blood lipids, coronary artery expansion, increase coronary blood flow and other effects, on patients with coronary heart disease and hypertension also have an auxiliary treatment.
Quercetin is non-toxic, therefore, for cancer, aging, cardiovascular disease treatment and prevention of great significance, with greater development value. The experiments currently under study will contribute to the production of new coronaviruses in the short term and will enable rapid action in future emergencies caused by SARS-CoV-2-like viruses.
The Italian researchers, who recruited 42 newly diagnosed outpatient patients for a two week trial, showed that 16 of the 21 people in the Quercetin group turned negative one week later, and 5 of them turned negative the second week, in the Conventional Treatment Group, however, only two individuals turned negative after one week.
The report concluded that Quercetin statistically shortened the time for molecular detection of positive to negative and reduced the severity of infection in the new crown. Because of the effectiveness of Quercetin in recovery in confirmed patients, the FDA has also recently approved it as a nutrient effective against coronaviruses. Last May, the NIH funded a trial of Quercetin in combination with vitamin C, vitamin D3, Essential fatty acid, micronutrient, and Bromelain, reports are coming in.
So why is it that cutting-edge medicine has turned quercetin into an essential nutrient to fight off new coronaviruses? Is it really that amazing? In the study, Quercetin was found to have a variety of biological properties, including antioxidant, anti-inflammatory, anti-bacterial, anti-viral, free radical scavenging, and immunomodulatory activity, which form the basis of overall health and disease resistance. These substances are natural pigments that have evolved over hundreds of millions of years. In addition to giving fruits and vegetables a colorful appearance, they have the most important role in strengthening the immune system, which is the key to the survival of plants against foreign invaders.
Summary of The Efficacy of Quercetin
1. Fight free radicals free radicals are unstable molecules in the body that increase the risk of disease and accelerate aging. Quercetin has antioxidant properties and is a more reliable source than vitamin C, Vitamin E, or Beta Carotene.
2. Quercetin helps reduce inflammation. Anti-new crown is also because it through the regulation of human factors, inhibit inflammatory body NLRP3, thus play a role in resistance.
3. Fight Cancer. Quercetin can play a role in the cell, prevent cell DNA mutation, in a natural mechanism to stop the cell proliferation, thereby freezing cancer cell growth.
4. Reduce the risk of heart disease the flavonoids. Quercetin play an important role in reducing the risk of cardiovascular diseases such as heart disease and stroke by improving the health of blood vessel cells and blood flow.
5. Lower high blood pressure taking quercetin supplements may be an effective way to lower blood pressure. (According to a 2016 study by the American heart and Stroke Association)
6. Quercetin’s antioxidant properties help fight free radicals. Helps Prevent Neurodegeneration, such as Alzheimer’s disease or Parkinson’s disease.
7. Infection Prevention Quercetin has antibacterial properties and is effective against almost all types of bacteria. Especially those related to the gastrointestinal, respiratory, urinary, and skin, as well as viruses.
Scientists have been evaluating the potential protective effects of Quercetin on cancer, heart disease and histamine-releasing cells.
