Capers in Bloom

Quercetin & Capers vs Corona

For those who still don’t know what Sars-Cov-2 stands for, it’s the virus that causes Covid-19.

I have demonstrated in previous articles that I belong to the group or side of the battlefield that believes corona can be beaten with a healthy diet in combination with certain food supplements. This is in sharp contrast to those who believe a vaccine is our only way of salvation. I stand on the side of those who believe we can fight covid-19 by giving our body the ammunition to fight ( antiviral design ). I believe we can and we should!

Curcumina, found in curcuma, is one of them. Now scientists have found quercetin to be effective against corona as well.

In other words, quercetin is the latest scientific discovery to fight the corona virus. That’s good news as it’s yet another argument against the school that says a vaccine is the only way out. Why wait for a vaccine if you could have your health in your own hands!

First, how does covid advance in our bodies?

In March 2020 a team of German scientists managed to find the main enzyme behind the virus’s replication process. They called it 3CLpro. Since then the scientific world has been searching for a substance capable of disabling the virus to stop it from performing its function.

Recently a team of Spanish and Italian researchers has indentified quercetin as very promising for this task. Computer simulations showed that quercetin effectively blocks the enzymatic activity of the 3CLpro protein, which is lethal for SARS-CoV-2.

The bad news is that gastric juices ( the ones in the stomach ) break down the quercetin molecule. In order for its antimicrobial effect in the alvear cells of the lungs ( where Covid attacks ) to be most efficient, quercetin should be applied via the nose or through an inhaler.

The research is still in its initial phase and it might take at least a year for clinical trials to begin. With powerful pharmaceautical companies in Spain being scarce, one should hope a leading global company will financially support the research.

Quercetin has already shown to have antioxidant and anti-inflammatory effects which might help reduce inflammation, kill cancer cells, control blood sugar, and help prevent heart disease.



Quercetin is a plant pigment (flavonoid). It is found in many plants and foods, such as red wine, onions, green tea, apples, berries, Ginkgo biloba, St. John’s wort, American elder, and others. Buckwheat tea has a large amount of quercetin.

Capers : the richest source of quercetin

What are capers?

Archaeological evidence for human caper consumption dates back as far as 10,000 years, according to archaeological findings from Mesolithic soil deposits in Syria and late Stone Age cave dwellings in the Greece and Israel. Capers have traditional been used as folk medicine for hundreds if not thousands of years and are in current use or study for their potential as anti-cancer, anti-diabetic and anti-inflammatory properties, and their possible circulatory and gastrointestinal benefits.

For a nice explanation on what are capers, I strongly recommend: “What are capers”.

Source of quercetin

By far the richest source of quercetin is capers. Although they look like berries, capers are actually tiny flower buds that grow on shrubs throughout the Mediterranean region.

According to data collected by the USDA, raw capers provide 234 milligrams of quercetin per 100 grams (3.5 ounces). Canned capers in brine — as they are commonly eaten — provide 173 milligrams of quercetin. In comparison, 3.5 ounces of raw onions provide 39 milligrams, and the same amount of boiled asparagus has 15 milligrams, according to the USDA.

In spite of their high quercetin content, one should be careful not overeating on them. As they most often come salted, too much sodium can raise your blood pressure and increase the risk of heart disease and stroke. Any positive effects quercetin might have on your heart health would be counteracted by such a high sodium intake.

The best strategy for stocking up on quercetin and a host of other nutrients is to eat a wide variety of colorful fruits and vegetables every day. You may want to supplement as well by taking once or twice a day a 500 mg capsule. Just like curcumina, quercetin is better absorbed when in combination with bromelain.


What’s there to Remember

Quercetin offers an exciting approach to COVID-19, but there is no direct evidence to support supplementation yet. More research is being done. But till then and for now, one might as well integrate a quercetin supplement in the daily diet and stock up on quercetin rich fruits, vegetables and plants.

When found in many healthful plant foods it is absorbed better from whole food than supplements! Like curcumin, quercetin represents a fantastic integrated approach to our health.
