Ginger and ginger hypertension: effect on blood pressure and blood vessels

High blood pressure (hypertension) affects 30% of Belgian adults according to Sciensano. It is the leading modifiable risk factor for stroke, heart attack, and kidney failure. Ginger is being studied for its natural vasoactive effects.

2019 Meta-analysis: results on blood pressure

A meta-analysis in Phytomedicine (Wang et al., 2019) integrating 6 randomized controlled trials (n=357) shows:

• Systolic pressure: average reduction of -6.36 mmHg
• Diastolic pressure: reduction of -2.12 mmHg
• Significant effect for supplementation ≥3g/day
• More pronounced effect in patients with stage 1 hypertension

For reference: a 5-6 mmHg reduction in systolic pressure reduces the risk of stroke by 13% and heart attack by 9% (meta-analysis Blood Pressure Lowering Treatment Trialists).

Vascular mechanisms of ginger

1. Calcium channel inhibition

[6]-gingerol inhibits voltage-dependent calcium channels (Vmax) in vascular smooth muscle cells — the same mechanism as calcium channel blockers (amlodipine, verapamil). Result: vasodilation of arterioles (Ghayur & Gilani, 2005, Journal of Cardiovascular Pharmacology).

2. Muscarinic receptor stimulation

Ginger extracts stimulate endothelial muscarinic receptors, inducing the release of nitric oxide (NO) — the primary physiological vasodilator.

3. ACE inhibition

Ginger moderately inhibits angiotensin-converting enzyme (ACE), a mechanism identical to ACE inhibitor drugs (lisinopril, enalapril) — but with much lower potency.

4. Mild diuretic effect

Ginger slightly increases diuresis, helping to reduce plasma volume and thus blood pressure.

5. Anti-platelet aggregation action

Reduction of blood viscosity → improvement of vascular rheology.

INTI vs. antihypertensives: putting it into perspective

Important: Ginger is NOT a treatment for medically diagnosed high blood pressure. Antihypertensives (ACE inhibitors, sartans, beta-blockers) have level 1 evidence with reductions of 10-20 mmHg.

The role of ginger is that of a preventive and optimizing supplement:

• Pre-hypertension (130-139/80-89 mmHg) without immediate medical indication
• Complement to a healthy lifestyle (DASH diet, exercise, salt reduction)
• Normotensive patients seeking to preserve their vascular health

Important precautions

• Interaction with antihypertensives: potentially additive effect → monitor blood pressure if taken concomitantly
• Orthostatic hypotension: increased risk if combined with diuretics
• Severe or poorly controlled hypertension: medical treatment is a priority

INTI Drink and vascular health

The INTI shot is part of a cardiovascular routine:

• Ginger: vasodilatory and anti-aggregating effect
• Curcumin + piperine: endothelial anti-inflammatory ginger
• Organic erythritol: GI 0, no glycemic impact (sugar raises blood pressure)
• 1.19g sugar/100ml: neutral glycemic load

Recommendation for vascular health: 1 INTI shot daily in the morning, for 3+ months.
