Allergic rhinitis, another common type of allergy, is characterized by inflammation of the nasal passages. Various allergens, including dust mites, pet dander, and certain foods can trigger it.
Allergic asthma is a chronic condition that causes inflammation and narrowing of the airways, leading to wheezing, coughing, and shortness of breath. While quercetin cannot replace standard asthma medications, some studies suggest that it may help reduce asthma-related inflammation and improve lung function.
It is always best to consult with a healthcare professional before initiating any new treatment regimen. In conclusion, quercetin shows promise as a natural remedy for allergies due to its ability to inhibit histamine release and reduce inflammation.
While more research is needed to fully understand its mechanisms of action and effectiveness, incorporating quercetin-rich foods or supplements into your allergy management plan may relieve symptoms.
Quercetin, a natural plant pigment known as a flavonoid, has gained attention for its potential to relieve allergy symptoms. This compound is found in various fruits, vegetables, and herbs, including apples, onions, berries, and green tea.
One of the notable advantages of quercetin is its potential to provide immediate relief from allergy symptoms. By suppressing histamine release and reducing inflammation, quercetin can help alleviate the nasal congestion, sneezing, itching, and watery eyes that often accompany allergic reactions.
When allergens, such as pollen or pet dander, enter the body, they trigger an immune response that leads to the release of histamine. Histamine is responsible for the uncomfortable symptoms experienced during an allergic reaction. Quercetin works by inhibiting the release of histamine, thus reducing the severity of these symptoms.
It is best used as a complementary approach in mild to moderate cases. In addition to its immediate effects, quercetin may provide long-term benefits for allergy sufferers.
Regular supplementation with quercetin has been associated with reducing the frequency and intensity of allergy symptoms over time. Chronic inflammation has been linked to various health issues, including allergies, asthma, and autoimmune disorders.
By reducing inflammation, quercetin may provide additional protection against these conditions. While quercetin is generally considered safe for most people, it is essential to be aware of potential side effects and risks associated with its use. Common side effects of quercetin supplementation are typically mild and may include digestive symptoms such as an upset stomach, nausea, or diarrhea.
If these occur, reducing the dosage or discontinuing use may alleviate the symptoms. Quercetin has a good safety profile when taken within the recommended dosage. However, high doses or long-term use may be associated with potential risks, such as kidney damage or interference with certain medications, including blood thinners, antibiotics, and chemotherapy drugs.
It is crucial to speak with a healthcare professional before starting quercetin supplementation, especially if you have any pre-existing medical conditions or if you are taking any medications or supplements.
It is generally recommended to start with a low dosage and gradually increase if necessary. A typical dosage range is between mg daily, preferably divided into two or three doses. However, it is crucial to consult with a healthcare professional to determine the most appropriate dosage for your specific needs.
In conclusion, quercetin shows promising potential in providing relief from allergy symptoms. Its antihistamine and anti-inflammatory properties make it a valuable natural option for those seeking complementary approaches to manage allergies.
However, it is essential to approach quercetin supplementation with caution, considering individual factors and consulting with a healthcare professional to ensure its safe and appropriate use. Mon - Thurs: AM - PM Fri: AM - PM Sat - Sun: Closed.

Scientists have long considered quercetin, and other flavonoids contained in fruits and vegetables, important in cancer prevention. People who eat more fruits and vegetables tend to have lower risk of certain types of cancer. Animal and test tube studies suggest that flavonoids have anti-cancer properties.
Quercetin and other flavonoids have been shown in these studies to inhibit the growth of cancer cells from breast, colon, prostate, ovarian, endometrial, and lung tumors. One study even suggests that quercetin is more effective than resveratrol in terms of inhibiting tumor growth.
Another found that frequent intake of quercetin-rich foods was associated with lower lung cancer risk. The association was even stronger among subjects who smoked more than 20 cigarettes daily, and a third suggests that quercetin slows tumor growth in the laboratory in leukemia cells.
Fruits and vegetables are the primary dietary sources of quercetin, particularly citrus fruits, apples, onions, parsley, sage, tea, and red wine. Olive oil, grapes, dark cherries, and dark berries such as blueberries, blackberries, and bilberries are also high in quercetin and other flavonoids.
Quercetin supplements are available as pills or capsules. They are often packaged with bromelain an enzyme found in pineapple because both are anti-inflammatories.
Other flavonoid-rich extracts include those from grapeseed, bilberry, Ginkgo biloba , and green tea. There are also water-soluble forms of quercetin available, such as hesperidin-methyl-chalcone HMC or quercetin-chalcone.
Quercetin is generally considered safe. Side effects may include headache and upset stomach. Preliminary evidence suggests that a byproduct of quercetin can lead to a loss of protein function.
Very high doses of quercetin may damage the kidneys. You should take periodic breaks from taking quercetin. If you are being treated with any of the following medications, you should not use quercetin supplements without talking to your health care provider first. There is some concern that quercetin may reduce the effectiveness of certain antibiotics.
Speak with your doctor. Quercetin may enhance the effect of these drugs, increasing your risk for bleeding. Anticoagulants include:. Test tube and animal studies suggest that quercetin may enhance the effects of doxorubicin and cisplatin, which are two chemotherapy medications used to treat cancer.
In addition, some doctors believe taking antioxidants at the same time as chemotherapy can be harmful, while others believe it can be helpful. In one study, combining quercetin with the anti-tumor drug doxorubicin, increased the drug's beneficial effects on breast cancer cells. In another, taking quercetin alongside cisplatin reduced the medicines' therapeutic effects in ovarian cancer cells.
Talk to your oncologist before taking any supplements if you are undergoing chemotherapy. Quercetin may interfere with the body's absorption of this drug, which is used to suppress the immune system.
Since quercetin affects the liver, concomitant use with medications that are changed by the liver may alter how the body metabolizes these medications.

Some studies have suggested that quercetin may lead to a reduction in allergy symptoms such as sneezing, itching, and nasal congestion. Allergic reactions can produce oxidative stress, leading to cell damage. This may contribute to a reduction in allergy-related tissue damage.
Quercetin, a natural flavonoid found in various foods, has shown promise in providing relief for different types of allergies. Seasonal allergies, often referred to as hay fever, are triggered by allergens such as pollen from trees, grasses, and weeds.
Symptoms include sneezing, runny nose, itchy eyes, and congestion. Asthma is a chronic respiratory condition that can be exacerbated by allergens. Allergic asthma, in particular, is characterized by airway inflammation and bronchoconstriction triggered by allergens.
Food allergies involve adverse reactions to specific foods , often leading to symptoms like hives, gastrointestinal discomfort, and in severe cases, anaphylaxis. Contact dermatitis is an allergic reaction that occurs when the skin comes into contact with allergens, such as certain metals or cosmetics.
Allergies to pet dander, saliva, or urine can cause respiratory symptoms, sneezing, and skin rashes [ 3 ]. Selecting the right quercetin supplement is crucial to ensure its effectiveness and safety in managing allergies and other health concerns.
With various quercetin products available on the market, making an informed decision is essential. Quercetin supplements come in different forms, such as quercetin dihydrate and quercetin glycosides.
Quercetin dihydrate is often considered more bioavailable, meaning it may be better absorbed by the body. Quercetin dihydrate is one of the most common forms of quercetin found in supplements [ 4 ]. It is derived from a variety of plant sources, including apples, onions, and citrus fruits.
Quercetin dihydrate is often used in research studies due to its relatively high bioavailability, meaning it is readily absorbed by the body. Quercetin glycosides are naturally occurring compounds in plants. In this form, quercetin is bound to a sugar molecule, which can affect its bioavailability.
While quercetin glycosides are found in many foods, they may have lower absorption rates compared to quercetin dihydrate. This form is believed to have higher bioavailability than quercetin glycosides.
However, quercetin aglycone is less common in foods and supplements. Quercetin quercitrin is a specific type of quercetin glycoside. It is found in foods such as capers and onions.
Some research suggests that quercetin quercitrin may have unique health benefits, although further studies are needed to confirm these effects. Rutin is another flavonoid compound that is closely related to quercetin. Rutin is commonly found in foods like buckwheat, apples, and citrus fruits.
Look for quercetin supplements from reputable brands that adhere to strict quality control standards. However, individual responses can vary, and some people may require higher or lower doses to achieve the desired effects.
The concentration of quercetin in a supplement can vary widely. For example, a supplement may contain mg of quercetin dihydrate, which is the actual amount of quercetin in the product.
For allergy management, a lower dose may be effective, while individuals using quercetin for other purposes, such as antioxidant support, may require higher doses.
Consult with a healthcare provider to determine the optimal dosage for your goals. Age, overall health, and underlying medical conditions can influence the appropriate quercetin dosage. Children may require lower doses, and individuals with certain health conditions or taking medications should consult with a healthcare provider before starting any supplementation regimen.
Some individuals may choose to take quercetin in combination with other supplements or vitamins to enhance its effects.

Allergies Uncontrolled blood sugar in a variety of forms ranging from the seasonal rhinitis such Quercstin hay Quercetin and allergies, stuffy nose, itchy and Enhancing self-care in diabetes Quercetin and allergies, to important illnesses like Qercetin, eczema, allergiee hives. Querxetin the body is not used to and does not welcome certain allergens, an allergic reaction is triggered and immunoglobulins are released. These trigger an inflammatory response and sets up a cascade of cell-mediated reactions where the tissues become swollen with cellular fluids build-up which then causes difficulty in breathing as well as swelling in the affected area. Controlling of the inflammatory response is, therefore, critical in normalization of allergic reaction whether it is airborne or food related. This is where conventional antihistamine medications come into play, but many of us are not aware that there are several natural supplements that can also help tame this response such as quercetin for allergies.
