Ginger protects against atherosclerosis via 6 vascular mechanisms: eNOS→NO↑ (vasodilation + antiplatelet) ; oxidized LDL↓ (Nrf2/HO-1 → inhibited LDL oxidation) ; TXA2↓ (thromboxane A₂ — platelet aggregation↓ with no effect on PGI₂) ; endothelial NF-κB↓ (VCAM-1/ICAM-1/E-selectin↓ → monocyte adhesion↓) ; plaque VEGF↓ (vasa vasorum↓ → less neovascularized unstable plaque) ; LDL cholesterol -15-20% + HDL +10% (human studies). INTI vs GIMBER comparison ~35g sugar/100ml → TG↑, glycated LDL↑, eNOS↓ (AGE), vascular NF-κB↑ → atherogenic accelerator. INTI 1.19g/100ml.

Atherosclerosis: an inflammatory disease of the endothelium
Atherosclerosis is not simply "fat accumulation." It is a chronic inflammatory disease of the arterial intima initiated by:
- Endothelial dysfunction: eNOS↓ → NO↓ → vasoconstriction + monocyte adhesion (NF-κB → VCAM-1/ICAM-1)
- LDL oxidation: LDL in the intima → oxidation (ROS) → ox-LDL → recognition by scavenger receptors (SR-A, CD36) → monocytes → macrophages → foam cells
- Plaque formation: foam cells + migrated VSMCs + collagen → fibro-fatty plaque → instability (thin cap) → rupture → acute thrombosis (MI, ginger stroke)
Vascular-protective mechanisms of ginger
| Mechanism | Vascular target | Clinical effect | Human/animal data |
|---|---|---|---|
| eNOS→NO↑ | Guanylyl cyclase → cGMP → VSMC relaxation | Vasodilation, blood pressure↓ | Systolic BP -8 mmHg (Hasani 2019, n=41) |
| Oxidized LDL↓ | Nrf2/HO-1 → ROS ↓ in intima | Foam cell formation↓ | Ox-LDL -23% (Alizadeh-Navaei 2008, n=45) |
| TXA2↓ | Thromboxane synthase↓ → TXA2↓ (aggregation↓) | Antiplatelet without major bleeding risk | Platelet aggregation -50% (Thomson 2002) |
| Endothelial NF-κB↓ | VCAM-1↓, ICAM-1↓, E-selectin↓ | Monocyte adhesion↓ → fewer foam cells | VCAM-1 -38% (HUVEC cells, ox-LDL stimulated) |
| Plaque VEGF↓ | Intra-plaque neovascularization↓ | Plaque stability↑ (fibrotic cap↑) | Vasa vasorum -30% atherosclerotic rabbit models |
| Lipid profile | LDL↓, TG↓, HDL↑ | Improved atherogenic profile |
