Raynaud's disease causes spasms in the blood vessels of the fingers and toes, leading to blanching, pain, and numbness in cold weather. Ginger is one of the most studied natural vasodilators for this condition.
How ginger combats Raynaud's
Ginger improves peripheral circulation through several mechanisms:
- Vasodilation: Gingerols stimulate the production of nitric oxide (NO) by the endothelium, relaxing the arterioles in the extremities.
- Anti-platelet aggregation: Thins the blood in microvessels, facilitating flow in contracted capillaries.
- Thermogentic effect: Increases peripheral body temperature by 1 to 2°C within 30 minutes of ingestion.
- anti-inflammatory-science-utilisation">Anti-inflammatory ginger: Reduces vascular inflammation-natural-remedy">inflammation underlying secondary Raynaud's.
Clinical studies
One study (Prostaglandins, Leukotrienes and Essential Fatty Acids, 2019) shows that 2g of ginger/day for 8 weeks reduces the frequency of Raynaud's attacks by 35% and the duration of episodes by 40%. Infrared thermography confirms a 2.3°C increase in finger temperature after supplementation.
Turmeric: complementary vascular protection
INTI's turmeric protects the vascular endothelium against cortisol-naturel">ginger oxidative stress. Curcumin improves endothelial function comparably to physical exercise (American Journal of Cardiology, 2020). This dual protection of ginger + turmeric is particularly relevant for secondary Raynaud's (linked to an autoimmune disease).
INTI Protocol for Raynaud's
- Winter (prevention): 2 INTI shots/day — morning + before going out in the cold.
- Acute attack: 1 INTI shot in hot water — double effect (vasodilating ginger + heat).
- Secondary Raynaud's: 3 INTI shots/day (sustained anti-inflammatory action).
The absence of added sugar is important: sugar causes a reactive vasoconstriction after a glycemic peak, worsening Raynaud's symptoms.
Conclusion
Ginger is an effective natural vasodilator for Raynaud's disease. INTI Drink — organic ginger in Belgium + turmeric, sugar-free — offers a daily solution to improve circulation in the extremities and reduce attacks.
