New Study Shows Chemical Found in Green Leafy Vegetables Can Slow the Spread and Treat Illnesses Caused by COVID-19 and Other Common Cold Viruses

According to a study led by Johns Hopkins Children’s Center, a chemical that can be found in green leafy vegetables could slow the spread and treat illnesses caused by Covid-19 and other common cold viruses.

Researchers at John Hopkins Children’s Center discovered from their lab experiments on mice that “sulforaphane, a plant-derived chemical, known as a phytochemical, already found to have anti-cancer effects, can inhibit the replication of SARS-CoV-2, the coronavirus that causes COVID-19, and another human coronavirus in cells and mice.”

“While the results are promising, the researchers caution the public against rushing to buy sulforaphane supplements available online and in stores, noting that studies of sulforaphane in humans are necessary before the chemical is proven effective, and emphasizing the lack of regulation covering such supplements,” Hopkins Medicine stated.

Sulforaphane can be found in cruciferous vegetables like broccoli sprouts, broccoli, cauliflower, kale, Brussels sprouts, cabbage, both red and white varieties, bok choy, watercress, arugula, also known as rocket.

“When the COVID-19 pandemic started, our multidisciplinary research teams switched our investigations of other viruses and bacteria to focus on a potential treatment for what was then a challenging new virus for us,” according to Children’s Center microbiologist and senior author of the paper Lori Jones-Brando, Ph.D.

“I was screening multiple compounds for anti-coronavirus activity and decided to try sulforaphane since it has shown modest activity against other microbial agents that we study,” she added.

According to Alvaro Ordonez, M.D., the first author of the paper and an assistant professor of pediatrics at the Johns Hopkins University School of Medicine, sulforaphane and remdesivir work better combined than alone is very encouraging.

“What we found is that sulforaphane is antiviral against HCoV-OC43 and SARS-CoV-2 coronaviruses while also helping control the immune response,” Ordonez said.

“This multifunctional activity makes it an interesting compound to use against these viral infections, as well as those caused by other human coronaviruses,” he added.

Read the summary of their finding below:

The ongoing SARS-CoV-2 pandemic has created the immediate need for effective therapeutics that can be rapidly translated to clinical use. Despite the introduction of vaccines, effective antiviral agents are still necessary, particularly considering the potential effects of viral variants. New oral antivirals targeting viral enzymes (e.g., molnupiravir and Paxlovid) have recently been approved or are in the process of review for emergency use approval by regulatory agencies, with many more currently under development.

However, this approach can be affected by the emergence of viral variants that change the affinity of the drug to the viral protein. An alternative approach is to target host mechanisms required by the virus to infect cells and replicate. Host-directed therapy is advantageous as it allows preexisting drugs to be repurposed, may provide broad-spectrum inhibition against multiple viruses, and is generally thought to be more refractory to viral escape mutations.

Following exploratory experiments using the in vitro CPE inhibition assay, SFN was identified as a promising candidate to target the host cellular response, given that it is orally bioavailable, commercially available at low cost, and has limited side effects. We observed that SFN has dual antiviral and anti-inflammatory properties against coronaviruses. We determined that SFN has potent antiviral activity against HCoV-OC43 and multiple strains of SARS-CoV-2, including Delta and Omicron, with limited toxicity in cell culture. The similar results observed between the coronaviruses evaluated suggest that SFN could have broad activity against coronaviruses, a feature that may prove invaluable as new strains of pathogenic coronaviruses enter the human population. Moreover, synergistic antiviral activity was observed in vitro between SFN and remdesivir against both types of coronaviruses tested; comparable synergism in vivo would be advantageous in clinical scenarios where remdesivir is currently being used. We demonstrated in vivo efficacy of prophylactic SFN treatment using the K18-hACE2 mouse model of SARS-CoV-2 infection. Prophylactic SFN-treatment in animals reduced viral replication in the lungs by 1.5 orders of magnitude, similar to that reported for remdesivir in the same mouse model. By comparison, BALB/c mice infected with mouse-adapted SARS-CoV-2 had a 1.4 log10 reduction in viral titers when treated with 300 mg/kg of nirmatrelvir 4 h after infection. As expected, SFN treatment also modulated the inflammatory response in SARS-CoV-2-infected mice, leading to decreased lung injury.

In summary, we documented that SFN can inhibit in vitro and in vivo replication of SARS-CoV-2 at pharmacologically and potentially therapeutically achievable concentrations. Further, it can modulate the inflammatory response, thereby decreasing the consequences of infection in mice when administered prior to infection. Given that SFN is orally bioavailable, commercially available, and has limited side effects, our results suggest it could be a promising approach for the prevention and treatment of COVID-19 as well as other coronavirus infections. Further studies are needed to address these possibilities.

Sulforaphane exhibits antiv… by Jim Hoft

Most green leafy vegetables such as kale, collard greens, broccoli, spinach, cabbage, and lettuce contain high vitamin K.

According to Harvard University, Vitamin K helps to make four of the 13 proteins needed for blood clotting, which stops wounds from continuously bleeding so they can heal. People who are prescribed anticoagulants (also called blood thinners) to prevent blood clots from forming in the heart, lung, or legs are often informed about vitamin K.

One reader of Gateway Pundit shared his knowledge about vitamin K found in green leafy vegetables.

Broccoli and green leafy vegetables have been prohibited for me to consume because of their high concentration of vitamin K which is the \’Blood Clotting\’ vitamin. K is ok in normal people, however. if someone is already on a blood thinner for medical necessary reasons, i.e. an artificial heart valve, it could, and does in my case, cause a decrease in the blood thinner, coumadin, affect. I have an artificial aoritic valve and have successfully stayed within my prothrombin range for 20+ years. The few times that I consumed brocolli it was because I was trending out of range and it had a noticiable affect almost immediately as indicated on my nest, two week, Pro-time check, If someone has been already compromised in regulating PT it could be fatal to take any additional vitamin K from any known source. There are many people that do take blood-thinning medications for many other reasons. Thank you, Jim
