Conditions
Brief summary
Quercetin is a flavonoid dietary supplement that occurs in many edible fruits and vegetables. It has remarkable antioxidant, anti-inflammatory, immunoprotective and antiviral properties. It is widely used to boost the body immune system against infections and keeping healthy life-style. The purpose of the present study is to investigate the potential benefits of quercetin for preventing COVID-19 disease progression and symptoms improvement in the early stage of infection.
Detailed description
The strong antioxidant and anti-inflammatory properties of quercetin are closely related to its effective fight against a variety of disease conditions related to inflammation, including: viral infections, allergies, asthma, hay fever, arthritis, respiratory diseases, hardening of the arteries (atherosclerosis), high cholesterol, heart disease and circulation problems, insulin resistance and diabetes, eye-related disorders, including cataracts, stomach ulcers, cognitive impairment, gout, cancer, chronic fatigue syndrome, inflammation of the prostate, bladder, and ovaries, chronic infections of the prostate, skin disorders, including dermatitis and hives. Quercetin can help stop damaging particles in the body known as free radicals, which damages the cells by natural oxidation processes. It can also reduce the expression of inflammatory genes in the cells. Quercetin has been shown to be effective against broad range of viruses including human respiratory syncytial virus (hRSV), rhinovirus, echovirus, coxsackievirus, poliovirus, parainfluenza type 3, Herpes Simplex Virus-1, cytomegalovirus, SARS-CoV-1, dengue virus, and Hepatitis C virus. The purpose of the present study is to investigate the potential benefits of quercetin for preventing COVID-19 disease progression and improving symptoms in the early stage of infection.
