Ginger and Blood Pressure: What We Know Today

Based on current human evidence, ginger does not have proven, consistent blood pressure–lowering effects in people with hypertension. While laboratory and animal data suggest several cardiovascular actions, high‑quality clinical trials showing that ginger reliably lowers blood pressure in hypertensive adults are lacking. At this time, ginger should not be relied upon as a treatment for high blood pressure, and guideline-supported lifestyle changes and prescribed medications remain the standard of care. ^[1]

How Ginger Might Affect the Cardiovascular System

• Antiplatelet effects: Ginger can inhibit thromboxane formation and platelet aggregation, which means it may thin the blood at certain doses. This effect is clinically important for bleeding risk but does not equate to proven blood pressure reduction. ^[2]
• Gastrointestinal and metabolic effects: Ginger has been studied for nausea, gastric emptying, satiety, and possible hypoglycemic effects, but these are separate from blood pressure outcomes. Human data tying these effects to lower blood pressure are limited. ^[1]

What Clinical Evidence Says About Blood Pressure

• Direct trials on ginger for hypertension are limited and inconsistent. There are no large, well‑designed randomized trials demonstrating that ginger supplements significantly lower systolic or diastolic blood pressure in people with established hypertension. ^[1]
• Reviews that cover multiple nutraceuticals sometimes list ginger among foods of interest, but this reflects preliminary or mechanistic evidence rather than robust clinical proof. Unlike agents such as fish oil or garlic that have more human data, ginger’s blood pressure evidence remains sparse and not definitive. ^[3]

Safety Considerations if You Use Ginger

Even if you enjoy ginger in food or tea, it’s worth understanding safety points especially if you have hypertension and take medications.

• Bleeding risk and interactions: Ginger’s antiplatelet activity may increase bleeding risk, particularly with anticoagulants (e.g., warfarin) or antiplatelet drugs (e.g., aspirin, clopidogrel), and with NSAIDs. Case reports describe elevated INR and nosebleeds when ginger was used with blood thinners. ^{[4] [5]}
• Surgery: Because of potential blood‑thinning effects, supplements are generally advised to be stopped at least two weeks before surgery and avoided immediately after. ^[6]
• Special populations: Avoid ginger supplements if you have gallstones or bleeding disorders, and avoid during pregnancy/lactation due to limited safety data. ^[7]

How Ginger Compares With Proven Strategies

Lifestyle measures and medications have far stronger evidence for lowering blood pressure and reducing cardiovascular risk than ginger.

• Diet: The DASH eating pattern (rich in fruits, vegetables, low‑fat dairy; lower sodium) is a proven approach for blood pressure reduction and is widely recommended. This strategy has consistent clinical support, unlike ginger. ^[3]
• Other nutraceuticals: Some supplements (e.g., fish oil, garlic) show more consistent human data than ginger, but quality varies and they can still interact with medications. Always discuss supplements with your clinician before starting them. ^[3]

Practical Guidance for People With Hypertension

• Enjoy ginger as a culinary spice or occasional tea if you like the flavor. Dietary amounts are generally considered safe for most people, but they have not been proven to reduce blood pressure. ^[1]
• Be cautious with concentrated ginger capsules or extracts if you are on blood thinners or NSAIDs, have a bleeding disorder, or have surgery planned. Check with your healthcare professional before using ginger supplements. ^{[4] [6]}
• Focus on proven blood pressure strategies: sodium reduction, DASH-style eating, regular physical activity, limiting alcohol, weight management, good sleep, and adherence to prescribed medications. These approaches have clear, measurable benefits for hypertension control and long-term heart health. ^[3]

Quick Summary Table

Topic	What the evidence shows	Takeaway
Ginger’s effect on BP	No robust, consistent clinical trials showing significant BP reduction in hypertensive adults	Do not rely on ginger to lower BP
Mechanisms	Antiplatelet effects; various GI/metabolic actions in preclinical/limited human contexts	Not the same as proven BP lowering
Safety	Can increase bleeding risk, interacts with blood thinners/NSAIDs; stop before surgery; avoid with gallstones and during pregnancy/lactation	Discuss supplements with your clinician
Strong alternatives	DASH diet, lifestyle changes, and prescribed medications	Proven to lower BP and reduce risk

---

Bottom line: There isn’t strong clinical evidence that ginger lowers blood pressure in people with hypertension, and supplements can carry bleeding risks especially with blood thinners so it’s safer to focus on well‑supported lifestyle measures and medications for blood pressure control. ^{[1] [4] [3]}
