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.

SXS shows promise against blood stasis
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
214 people found this helpful
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.

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
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
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.

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.

Post-Covid, my family relied on quercetin to improve health. I ordered it for my mother, as her blood pressure rises and sometimes causes eye hemorrhaging. After starting quercetin, her eye issues cleared in three days instead of a week. Combined with magnesium and vitamin D, her pressure stabilises. My husband and I also took it as part of our Covid treatment regimen, leading to noticeable upgrades in our immune responses.

Remarkable blood pressure
4 people found this helpful
This product was a lifesaver! I purchased it just in time before I fell ill about a month later. My homemade hcq alongside this actively reduced my temperature and alleviated terrible aches. After two weeks, I measured my blood pressure and was astonished to see it drop from 150/100 to 118/85. The only downside is the hot maltodextrin which may disrupt gut health and affect blood glucose levels.

Thickened blood caution
My blood thickened after taking it with resveratrol. During menstruation, I passed clots instead of normal blood, which was quite frightening. I underwent blood tests which confirmed this issue, so I advise caution.

Quercetin from this brand is something I consistently take for myself and my loved ones. It acts as an internal rejuvenator, supporting blood vessel function, thinning the blood, and protecting cells from cholesterol. I take it twice yearly as a preventive measure, and I use it continuously for heart disease management.

We investigated whether quercetin, along with other flavonoids, impacts platelet activity, which is crucial for blood clotting. Using blood samples from healthy volunteers, we looked at how these compounds influence the activation states of platelets through a specialized laboratory technique.
Our findings showed that quercetin and the other flavonoids demonstrated significant antiplatelet activity, effectively blocking a key receptor involved in platelet aggregation. This work helps shed light on how these natural compounds may play a role in preventing cardiovascular issues by reducing unwanted blood clot formation.

We investigated the potential of Traditional Chinese Medicine (TCM) for finding natural medications to combat blood clots. Focusing on the plant Ledeb, we screened its components for their ability to inhibit thrombin, a key player in clot formation. Using advanced techniques, we identified eleven compounds, including quercetin, that demonstrated antithrombotic properties. Our results showed that specific components could effectively reduce thrombin activity, offering promising insights into natural treatments for thrombotic diseases. However, further studies are needed to confirm these findings and understand the mechanisms involved.
