B. ncbi.nlm.nih.gov/pubmed/30735748
C. ncbi.nlm.nih.gov/pubmed/30551359
22. Here is a study on the anti-inflammatory properties of Quercetin. It is specifically important given the potential of inhibiting the high cytokine storm induced by Covid-19,causing major complications like pneumonia etc.
23. Here’s another study on the anti inflammatory properties of Quercetin where we see inhibition of pro inflammatory cytokines:
24. In test-tube studies, quercetin reduced markers of inflammation in human cells, including the molecules tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6). Here are two studies with regard to that:
A. ncbi.nlm.nih.gov/pubmed/20943792
B. ncbi.nlm.nih.gov/pubmed/27294919
25. An 8-week study in 50 women with rheumatoid arthritis observed that participants who took 500 mg of quercetin experienced significantly reduced early-morning stiffness, morning pain, and after-activity pain. They had reduced markers of inflammation: ncbi.nlm.nih.gov/pubmed/27710596
26. Quercetin’s anti-inflammatory properties may provide allergy symptom relief. Studies found that it may block inflammatory enzymes and suppress inflammation-promoting chemicals, such as histamine.
A. ncbi.nlm.nih.gov/pubmed/27187333
B. ncbi.nlm.nih.gov/pubmed/18187018
C. ncbi.nlm.nih.gov/pubmed/21625024
27. Another study showed that taking quercetin supplements suppressed peanut-related anaphylactic reactions in mice:
28. Here is a study with regard to Quercetin’s efficacy on inhibiting the Zika virus:
29. Now let’s turn our attention to the possible effects of Quercetin on SARS-COV-2, otherwise known as COVID-19.
There are various ways Quercetin may be effective in inhibiting the effects of the coronavirus.
30. 1) Blocking Entry of Virus. Supercomputer simulations by the University of Tennessee and Oak Ridge National Labs to demonstrate which FDA approved chemical compounds may interfere with the coronavirus binding to cells. Out of 8000,Quercetin came in #5.
32. Yet more detail on the mechanism of how Quercetin may block virus entry into cells. Here is the table from the Supercomputer simulation mentioned above:
33. This seems to be the mechanism proposed by the Montreal researchers mentioned above. Here is a piece of the article mentioned above: mcgilltribune.com/sci-tech/montr… Image
34. 2) Quercetin acts as a Zinc Ionophore, allowing Zinc to pass the cell membrane and thereby inhibit the replication of the virus. Here is the study demonstrating this:
35. This is essentially the same process behind chloroquine/Hydroxychloroquine as they are both Zinc Ionophores. This is one of the leading theories behind their efficacy as anti-viral drugs.
36. Here is a great video demonstrating how chloroquine/Hydroxychloroquine work as zinc ionophores to inhibit virus replication:
37. As an aside I would like to share two recent documents showing the strong efficacy of Hydroxychloroquine and Zinc in fighting Covid-19.
38. B) Here is the second document on Hydroxychloroquine’s efficacy on treating COVID-19:
39. Zinc- The following is a study showing Zn2+ Inhibits Coronavirus and Arterivirus RNA Polymerase Activity In Vitro and Zinc Ionophores Block the Replication of These Viruses in Cell Culture:
40. Here is a trial on the efficacy of Zinc on the common cold: ncbi.nlm.nih.gov/pubmed/15496046
42. This is a very detailed explanation on the connection between chloroquine, zinc and Quercetin and illustrates clearly how they share similar mechanisms.
43. 3) Another reason why Quercetin may be effective at combatting COVID19 is due to the fact that it may inhibit the cytokine storm induced by the coronavirus:
44. 4) Another potential Quercetin anti-Covid-19 mechanism:
47. I will now proceed to link articles and videos related to Quercetin’s potential to fight COVID-19.
