Quercitrin reduces platelet activation
Quercitrin inhibits platelet activation in arterial thrombosis.
High relevance, promising results
We explored the effects of quercitrin on platelet activation to better understand its role in blood clotting. Through comprehensive experiments—like assessing platelet aggregation and thrombus formation—we observed that quercitrin significantly hinders platelet activation. This means it impairs platelet aggregation and granule secretion, which are crucial in forming blood clots.

Moreover, quercitrin showed promise in preventing arterial thrombus formation without extending bleeding time, hinting at its potential as a treatment for thrombotic diseases. Overall, our findings suggest that quercitrin could be beneficial in managing blood clot-related conditions.

Quercetin reduces platelet activation
Quercetin inhibits platelet activation and ER-stress mediated autophagy in response to extracellular histone.
Significant findings in platelet health
We investigated how quercetin, a natural compound, can guard against the harmful effects of extracellular histones on platelets. Our study involved evaluating the interaction between histones and platelets in animal and lab settings.

We discovered that quercetin effectively inhibits histone-induced platelet activation and damage. This protection suggests that quercetin could be a valuable treatment option for conditions where histone toxicity plays a role, potentially assisting in the management of critical illnesses.

SXS shows promise against blood stasis
Mechanism investigation of Shi-Xiao-San in treating blood stasis syndrome based on network pharmacology, molecular docking and in vitro/vivo pharmacological validation.
High relevance for blood clot management.
We investigated how Shi-Xiao-San, a traditional Chinese herbal formula, affects blood stasis, which relates to conditions like thrombosis and coronary heart disease. Through advanced techniques, we identified over 45 compounds, such as quercetin, that may play crucial roles in reducing blood viscosity and improving vascular health. Our tests showed that Shi-Xiao-San works by influencing key pathways involved in blood flow and inflammation. While promising, further studies are necessary to fully understand its mechanisms and benefits for treating blood clotting disorders.

Supports blood vessels
The pandemic prompted me to explore various supplements to boost my immune system against the new virus. I discovered quercetin, an antioxidant that combats oxidative stress, prevents cytokine storms, and strengthens blood vessel walls. It improves microcirculation, aids normal blood clotting, and prevents blood clots, particularly in lung vessels. Additionally, it maintains proper functioning of the bronchi and lungs while exhibiting antiviral activity. Quercetin also facilitates zinc, a potent immune booster, to enter cells.

Eye hematoma relief
I ordered this for my mother, who frequently experiences high blood pressure and eye haemorrhages. After she starts taking quercitin, the eye bruising resolves in three days, rather than the usual week. When taken alongside magnesium and vitamin D for prevention, her blood pressure remains stable.

Blood pressure normalised
I purchased this quercetin as bioquercetin was unavailable. It's quite effective, though the capsules are large. After my encounter with Covid, I consumed it alongside curcumin and continue to do so. This supplement is miraculous for treating coronavirus and aiding recovery. It has normalised my blood pressure, alleviating the attacks I suffered from age 18, thanks to its beneficial effects on blood vessels.

Quercetin as anticoagulant examined
Studies on in vivo antithrombotic activity of quercetin, a natural flavonoid isolated from a traditional medicinal plant, African eggplant (Solanum indicum).
Relevant to cardiovascular health
We investigated the potential of quercetin, a compound from the African eggplant, to act as an anticoagulant. By using various methods including bioassay-guided fractionation, we studied its effects on blood clotting in mice. Our experiments revealed promising anticoagulant activities.

While quercetin shows effectiveness against clot formation, further research is needed to fully understand its mechanisms and therapeutic potential in treating cardiovascular diseases. Overall, this suggests quercetin may serve as a valuable herbal option for cardiovascular health.

Taxifolin inhibits NETosis, aids thrombo-inflammation
Taxifolin inhibits NETosis through activation of Nrf2 and provides protective effects in models of lupus and antiphospholipid syndrome.
High relevance for thrombo-inflammatory diseases
We investigated how taxifolin, a bioactive flavonoid, could impact diseases associated with blood clots like lupus and antiphospholipid syndrome (APS). Using in vitro assays and mouse models, we observed that taxifolin significantly inhibits the formation of neutrophil extracellular traps—an action known as NETosis—linked to inflammation and clotting. Notably, taxifolin reduced autoantibody formation and large-vein thrombosis in these models. This pioneering study suggests that taxifolin may offer protective benefits against thrombo-inflammatory conditions, making it an exciting area for further research.

Baiying Qingmai reduces thrombosis
Baiying qingmai formulation ameliorates thromboangiitis obliterans by inhibiting HMGB1/RAGE/NF-κB signaling pathways.
Research supports traditional remedy use
We explored how Baiying Qingmai Formulation (BF) affects thromboangiitis obliterans (TAO) by analyzing its chemical makeup and how it interacts with various signaling pathways.

Our findings showed that BF significantly inhibits important proteins related to inflammation and blood clotting. It not only decreases harmful cytokines but also increases protective metabolites in the bloodstream.

Ultimately, we believe BF offers a promising path to alleviate symptoms of TAO by reducing blood clots and improving vascular health in affected individuals.

Quercetin aids hemorrhoid treatment
Evaluation of the Efficacy and Safety of a Compound of Micronized Flavonoids in Combination With Vitamin C and Extracts of , , and for the Reduction of Hemorrhoidal Symptoms in Patients With Grade II and III Hemorrhoidal Disease: A Retrospective Real-Life Study.
Relevant study on hemorrhoid relief
We closely examined a retrospective study focused on how a blend of micronized flavonoids, including quercetin, can alleviate symptoms of grade II and III hemorrhoidal disease.

Patients taking this compound showed a notable 89.8% success rate in reducing hemorrhoid severity after just one week of treatment.

Improvements were seen across a range of symptoms with no reported side effects. Overall, this study suggests that quercetin, alongside other ingredients, may effectively help manage hemorrhoidal symptoms safely.
