The Relationship Between Hesperidin and Blood Vessels

1. Anti-platelet aggregation effect  

· Hesperidin does indeed have certain antiplatelet and blood rheology-improving effects. Its mechanism of action primarily involves regulating blood viscosity, inhibiting platelet aggregation, and improving microcirculation, rather than directly interfering with coagulation factors. Since hesperidin can inhibit ADP-induced platelet aggregation, it reduces the risk of thrombosis.

· Experimental studies have shown that after administering hesperidin (160–320 mg/kg) to rats with acute blood stasis models, the maximum platelet aggregation rate was significantly reduced, and both whole blood viscosity and plasma viscosity also decreased markedly. This mechanism is similar to aspirin's antiplatelet effect but with weaker potency.

2. Improving blood rheological parameters  

Improving blood rheology: Hesperidin can improve blood rheological properties, such as reducing blood viscosity and promoting blood circulation, thereby aiding in the prevention and treatment of cardiovascular diseases. Since hesperidin can reduce haematocrit (Hct), red blood cell aggregation index, and fibrinogen (Fib) levels, while prolonging prothrombin time (PT) and thrombin time (TT), it helps improve hypercoagulable blood states. These changes help alleviate microcirculatory disorders, particularly in patients with chronic venous insufficiency or hyperviscosity syndrome.

3. Enhancing vascular function  

As a vitamin P-like substance, hesperidin maintains normal vascular permeability, enhances capillary resilience, and reduces bleeding tendencies (such as gum bleeding or retinal bleeding). This differs from ‘blood thinning’ and instead indirectly improves blood circulation by protecting vascular endothelium. Hesperidin also inhibits abnormal platelet aggregation. By regulating the activity of coagulation factors, hesperidin reduces the risk of thrombosis, improves blood flow, and plays a positive role in preventing cardiovascular and cerebrovascular embolism.

4. Improving vascular structure and function

· Enhancing vascular elasticity: Hesperidin promotes the synthesis of collagen in the vascular basement membrane and increases elastin content, thereby improving the resilience of the vascular wall. For patients with varicose veins or increased capillary fragility, it can alleviate stasis and oedema.

· Promotes vascular dilation. By activating endothelial nitric oxide synthase (eNOS), it increases nitric oxide (NO) release, dilates blood vessels, and reduces peripheral resistance. Experimental studies have shown that daily consumption of orange juice improves vascular dilation capacity by 12%, aiding in blood pressure reduction and improved microcirculation.

5. Prevent cardiovascular disease

Hesperidin can promote cholesterol metabolism, reduce low-density lipoprotein (LDL) cholesterol levels in the blood, and thereby lower the risk of cardiovascular disease. It can also inhibit cholesterol absorption and synthesis, reduce cholesterol levels in the blood, and prevent cardiovascular disease. Hesperidin is a flavonoid compound primarily found in the peel and flesh of citrus fruits. It possesses various bioactive properties, including antioxidant, anti-inflammatory, blood pressure-lowering, and cholesterol-lowering effects. Since hesperidin can inhibit cholesterol absorption and synthesis, it reduces cholesterol levels in the blood and helps prevent cardiovascular diseases. Additionally, hesperidin also has immune-boosting properties.
