Effectiveness of Quercetin In The Treatment of SARS-COV 2
Abstract
In 1937, Albert Szent-Gyorgyi received a Nobel Prize for discovering vitamin C and flavonoids, as well as for exploring their biochemical properties. Originally, he gave the flavonoids the name "vitamin P" because of their effectiveness in reducing the permeability of blood vessels. This name was abandoned when it was realized that these substances were not really vitamins.
Quercetin is extracted from a variety of plant sources, including the onion peel and the seeds and pods of Dimorphandra mollis, a legume tree native to South America.
Although we are far from knowing everything about quercetin, its antioxidant, anti-inflammatory, and antihistamine (antiallergic) properties have been observed in numerous in vitro and animal studies.
Conditions: SARS (Severe Acute Respiratory Syndrome).
Primary outcome: Mortality rate; Need for ICU admission; treatment safety.
Enrollment: 200 participants.
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 200 participants or records.
