Quercetin – It’s Amazing!

Adding quercetin-rich foods into the diet or taking quercetin supplements can be beneficial for maintaining good health and preventing chronic diseases.

Quercetin is a flavonoid derived from plants pigments and is known for its allergy inhibiting, antioxidant, anti-inflammatory and potential anti-cancer qualities. Foods that commonly contain quercetin include onions, apples, grapes, berries, broccoli, citrus fruits, cherries, green tea, coffee, red wine, parsley, sage and capers.

Allergies

Quercetin has been shown to inhibit the release of histamine, thereby reducing the intensity of allergic symptoms. Histamines are chemicals released by our immune system in response to allergens, such as pollen or pet dander. They are responsible for triggering allergy symptoms like sneezing, itching, and watery eyes. Quercetin works by blocking the H1 receptor sites on mast cells, which are responsible for releasing histamine. By doing so, quercetin prevents histamine from binding to these receptors and triggering the allergic response.

Antioxidant

As an antioxidant quercetin eliminate free radicals, which are unstable molecules that travel through the body damaging cell membranes, DNA, and even cause cell death. 

Research shows quercetin can promote the antioxidant defense system and maintain oxidative homeostasis as well as enhance the antioxidant capacity of the body by regulating the level of glutathione (GSH).

Anti-inflammatory

Quercetin is also one of the most widely used bioflavonoids for the treatment of metabolic and inflammatory disorders to help reduce swelling, kill cancer cells, control blood sugar, and help prevent heart disease.

Inflammation is the body’s natural way to protect itself against harm (injury or fight an infection) and to begin the healing process. However, chronic inflammation can harm the body and contribute to many serious diseases and health conditions including cardiovascular disease, autoimmune and cancer.

Published in the 2016 Pharmacognosy Review research states, “Quercetin, a plant-derived aglycone form of flavonoid glycosides, has been used as a nutritional supplement and may be beneficial against a variety of diseases.  One of the core most remarkable properties of quercetin is its ability to modulate inflammation. Quercetin inhibits inflammatory enzymes cyclooxygenase (COX) and lipooxygenase thereby decreasing inflammatory mediators such as prostaglandins and leukotrienes. Some of the beneficial effects include cardiovascular protection, anticancer, antitumor, anti-ulcer, anti-allergy, anti-viral, anti-inflammatory activity, anti-diabetic, gastroprotective effects, antihypertensive, immunomodulatory, and anti-infective.”

A recent study published in the July 18, 2023, Pharmaceuticals journal showed, “Quercetin’s anti-inflammatory properties involve inhibiting the production of inflammatory cytokines and enzymes, making it a potential therapeutic agent for various inflammatory conditions. It also exhibits anticancer effects by inhibiting cancer cell proliferation and inducing apoptosis. Finally, quercetin has cardiovascular benefits such as lowering blood pressure, reducing cholesterol levels, and improving endothelial function, making it a promising candidate for preventing and treating cardiovascular diseases.”

Potential Anti-Cancer

Published in the August 15, 2022, journal Cancer Cell International, “Over the past few years, the cancer-related disease has had a high mortality rate and incidence worldwide, despite clinical advances in cancer treatment. The drugs used for cancer therapy, have high side effects in addition to the high cost. Subsequently, to reduce these side effects, many studies have suggested the use of natural bioactive compounds. Among these, which have recently attracted the attention of many researchers, quercetin has such properties. Quercetin, a plant flavonoid found in fresh fruits, vegetables, and citrus fruits, has anti-cancer properties by inhibiting tumor proliferation, invasion, and tumor metastasis. Several studies have demonstrated the anti-cancer mechanism of quercetin, and these mechanisms are controlled through several signaling pathways within the cancer cell. Many studies show that quercetin in combination with anticancer drugs and other anti-cancer bioactive compounds can have a greater effect.”
