What is quercetin? What are the health benefits of quercetin?
Quercetin is widely found in plants, especially citrus fruits. It is a yellow flavonoid that has been shown to have numerous health benefits, including anti-inflammatory, antioxidant, reducing allergic responses and assisting with anticancer activities. Quercetin has also been shown to improve exercise performance and cognitive function.
While all these health benefits are impressive, they really point to one underlying pillar of health, which is quercetin’s unique ability to stimulate and boost the immune system. Quercetin has a good reputation for keeping you healthy, especially at times where everyone else seems to be getting sick.

How does quercetin boost the immune system?
Quercetin is a potent antioxidant and anti-inflammatory compound that can help keep you from getting sick. It scavenges harmful free radicals, boosts immune function and reduces inflammation. Quercetin is found in fruits and vegetables, especially citrus, onions, apples, and berries. You can also take it as a supplement.
Mold and mycotoxin work is brutal when it's actually mold and frustrating when it isn't. The same brain fog, fatigue, and inflammation show up across all four toxic load types, which is why so many people spend months on the wrong protocol before that becomes obvious. The 2-minute What's Draining Your Brain Tool helps confirm or rule out mold as your dominant load before you commit to the next phase of work.
So how does quercetin keep you from getting sick?
By protecting your cells from damage, reducing inflammation and boosting your immune system, quercetin gives your body the tools it needs to fight off infections before they take hold.
How to make homemade quercetin, as shown in the video below:
Quercetin is highly potent in the skins of citrus like lemons, limes, and grapefruits. It is really simple to make, and with the cost of everything going up, it is nice to know how to make things like this yourself, so you have a choice.
If you boil the skins of these fruits or cut up pieces of the whole fruit and let it simmer for a few hours in water, keeping the lid on, you can make quercetin.
After the citrus simmers for a few hours, without removing the lid, let it sit and cool off for 8 hours. This is best done at night, so it is undisturbed and the lid is kept on without disturbing it.
I make homemade quercetin often and like to have a batch on hand to take a tablespoon every few hours at the onsight of any symptoms of seasonal sickness. I feel it works very well. I am rarely sick.
I also have store-bought quercetin in my pantry because the fresh, homemade concoction seen in the video lasts a few weeks in the fridge, and then it’s time to discard it and make a fresh batch. So there is a time where you may not have any on hand in the fridge.
Tyrese Gould Jacinto does a great job in the 8 minute video below showing exactly how to make a healthy and healing batch of quercetin.
She has been making this since she was young, and talks about how it keeps her and her loved ones healthy while she is making it. It is a good idea to take zinc supplements with this homemade quercetin to help with absorption.
It is a good idea to keep some shelf-stable quercetin on hand, in case you or a loved one comes down suddenly with symptoms and you don’t have time to make a batch. It is best to take a tablespoon of quercetin immediately when symptoms are just starting to be felt, and not delay.

What the research says about quercetin
Quercetin has genuinely encouraging research behind its reputation. According to PubMed, a review found quercetin acts as a natural mast-cell stabilizer that blocks the release of histamine and the inflammatory messengers involved in allergies (Shaik et al., 2006, Journal of Biological Regulators & Homeostatic Agents, PubMed), and a 2023 review described its broad anti-inflammatory and antioxidant actions plus a positive impact on immune function and allergy symptoms (Chiang et al., 2023, International Journal of Molecular Sciences, DOI). Most human evidence is still early, so treat quercetin as supportive: take it consistently and pair it with the basics.
