What's all the buzz about quercetin?
Quercetin, like hydroxychloroquine and ivermectin, is a zinc ionophore, facilitating the entry of zinc into cells where it interferes with viral replication, potentially suppressing COVID infection.
Could quercetin be of benefit against COVID, or for that matter, the common cold or the flu? As are always told to “follow the science”, what does science say?
A 2012 paper published in Antiviral Research found that quercetin inhibits rhinovirus (common cold) replication both in vitro and in vivo, meaning in the laboratory and in humans. Another 2016 paper in Viruses noted that quercetin inhibited influenza A (seasonal flu) virus entry into cells. Is quercetin a cure or panacea? Certainly not as we have no cure for these viral infections. But following the science leads to the conclusion that it helps. But what about for COVID?
Following the science, rather than the FDA Twitter feed, suggests that quercetin may be of benefit in COVID. A 2021 paper in the International Journal of General Medicine, a prospective, randomized, controlled clinical trial of 152 early-stage COVID patients, the type of study always demanded by Dr. Anthony Fauci and the medical smart set, concluded, “Quercetin is a safe agent and in combination with standard care, when used in the early stage of viral infection, could aid in improving the early symptoms and help in preventing the severity of COVID-19 disease.”
The same group published in the same journal, also in 2021, a smaller similarly designed clinical study concluding, “Quercetin statistically shortens the timing of molecular test conversion from positive to negative, reducing at the same time symptoms severity and negative predictors of COVID-19.”
