Is Ginger Tea Good For Your Kidneys?
For most people, ginger tea is safe for the kidneys—and it might even be beneficial. Ginger contains anti-inflammatory and antioxidant compounds that help protect kidney function.
Some studies suggest that ginger extracts can reduce oxidative stress, improve kidney function in diabetes, and protect against damage caused by toxins.
While these studies focused on ginger extract rather than ginger tea, the tea still contains some of the same beneficial compounds, just in lower concentrations.
But it’s not for everyone. If you have advanced kidney disease, take certain medications, or need to limit specific foods, you’ll want to check with your doctor before making ginger tea a daily habit.
Does Ginger Tea Contain the Same Compounds as Ginger Extract?
Most research on ginger and kidney health has used ginger extract, which is more concentrated than ginger tea. Ginger extract is made by isolating bioactive compounds from the ginger root, while ginger tea is made by steeping slices of fresh or dried ginger in hot water.
Even though ginger tea is less potent than an extract, it still contains some key active compounds, including:
- Gingerol – A powerful antioxidant and anti-inflammatory compound.
- Shogaol – Formed when ginger is dried or heated, known for its anti-inflammatory effects.
- Zingerone – Another antioxidant that may help reduce oxidative stress.
While the concentration of these compounds is lower in tea than in extract, regular consumption of ginger tea may still offer mild benefits for kidney health.
Benefits of Ginger Tea for Kidney Health
Ginger has been used in traditional medicine for centuries, but modern research is starting to confirm many of its health benefits—especially for the kidneys.
Most studies focus on ginger extract, which is far more concentrated than ginger tea, but since ginger tea contains some of the same active compounds, it may still offer mild kidney-supporting benefits.
Here’s how ginger tea might help your kidneys:
1. May Help Reduce Kidney Inflammation and Oxidative Stress
Your kidneys work hard to filter toxins and waste from your blood. Over time, this process can lead to oxidative stress and inflammation, which may contribute to kidney damage. Ginger contains natural antioxidants and anti-inflammatory compounds that may help counteract this damage.
One study found that ginger extract improved kidney health by reducing inflammation and oxidative damage in rats with kidney injury. Researchers observed increased levels of protective antioxidants like glutathione, while markers of cell damage significantly decreased.
What this means for you: While ginger extract is much stronger, drinking ginger tea may still provide some antioxidant benefits that help protect the kidneys from long-term damage.
2. May Help Protect Kidneys from Toxins
Kidneys are constantly filtering out harmful substances from the body, but exposure to toxins—like alcohol, medications, and environmental pollutants—can put them under serious stress. Studies suggest that ginger may have a protective effect against toxin-related kidney damage.
A study on ethanol-induced kidney damage found that ginger significantly reduced harmful waste buildup in the kidneys, including urea, creatinine, and uric acid. It also improved antioxidant activity, helping the kidneys function more efficiently.
What this means for you: If your kidneys are exposed to toxins, whether from alcohol, medications, or other sources, drinking ginger tea may offer some protective effects.
3. May Support Kidney Health in Diabetes
Diabetes is a leading cause of kidney disease. High blood sugar can damage the kidneys over time, leading to serious complications. Some studies suggest that ginger can help regulate blood sugar while also protecting kidney function.
A systematic review of animal studies found that ginger supplementation lowered key markers of kidney damage in diabetic rats. It also reduced oxidative stress and inflammation, two major contributors to kidney disease.
What this means for you: If you have diabetes or prediabetes, drinking ginger tea may support kidney health by helping to regulate blood sugar and reduce inflammation—but the effects are likely milder than ginger extract.
4. May Help Prevent Kidney Stones
Kidney stones form when certain minerals—like calcium and oxalate—build up in the kidneys and crystallize. While there’s no strong evidence that ginger can dissolve existing kidney stones, some research suggests it may help prevent them from forming in the first place.
Here’s how ginger may help:
✅ Diuretic Properties: Ginger tea may help increase urine output, reducing the concentration of stone-forming minerals.
✅ Anti-Inflammatory Effects: Kidney stones can irritate the urinary tract. Ginger’s anti-inflammatory compounds may help reduce irritation and discomfort.
✅ Possible Regulation of Oxalates: Some studies suggest that ginger may help regulate calcium and oxalate levels, two key minerals involved in kidney stone formation.

What this means for you: Ginger tea won’t dissolve kidney stones, but it may help prevent them by keeping your kidneys flushed and reducing inflammation.
5. May Support Kidney Function in People with Chronic Kidney Disease (CKD)
Chronic kidney disease (CKD) is a long-term condition where the kidneys gradually lose function. While ginger isn’t a cure, some studies suggest it may help slow down damage and improve certain kidney function markers.
A review of research on ginger and kidney health found that ginger extract supplementation was linked to:
✔️ Lower levels of creatinine and urea – High levels of these waste products in the blood indicate kidney dysfunction.
✔️ Improved antioxidant activity – Ginger’s antioxidants may help protect kidney cells from further damage.
✔️ Reduced inflammation – Since inflammation worsens CKD, ginger’s anti-inflammatory effects may be beneficial.
What this means for you: If you have kidney disease, ginger tea might help support kidney function, but always check with your doctor first—especially if you’re on medication.
Could Ginger Tea Be Bad for Your Kidneys?
For most people, ginger tea is safe and even beneficial for kidney health. However, there are certain cases where it may not be the best choice. Let’s look at when ginger tea might not be ideal.
1. Kidney Transplant Patients Should Be Cautious
If you’ve had a kidney transplant, drinking ginger tea may not be a good idea. The main concern is that ginger can interact with immunosuppressant medications, which are essential for preventing organ rejection.
- Ginger may affect drug metabolism, possibly altering how medications like tacrolimus or cyclosporine work.
- It has mild blood-thinning properties, which could increase the risk of bleeding, especially after surgery.
What this means for you: If you’ve had a kidney transplant, avoid ginger tea unless your doctor gives you the green light.
2. Can Ginger Tea Worsen Kidney Disease?
Ginger tea is not harmful to most people with chronic kidney disease (CKD) and may even provide some benefits. However, there are a few things to keep in mind:
- Medication Interactions – Ginger can interact with blood pressure medications, blood thinners, and diabetes drugs, which many CKD patients take.
- Dietary Restrictions – Some advanced CKD patients have to limit potassium or oxalates, though ginger is generally low in both.
What this means for you: If you have kidney disease, ginger tea is likely safe in moderation, but check with your doctor if you’re on medication or have dietary restrictions.
3. Can Too Much Ginger Be Harmful to Kidneys?
While ginger tea is generally safe, excessive amounts may not be ideal for kidney health. Drinking too much can lead to:
- Lower blood pressure, which may be an issue for people with CKD who are on medications to regulate it.
- Increased risk of bleeding, especially if you take blood thinners.
What this means for you: Stick to moderate amounts—1 to 2 cups per day is generally considered safe.
Final Thoughts: Should You Avoid Ginger Tea?
For most people, ginger tea is not bad for the kidneys—and in many cases, it’s actually beneficial. However, those with a kidney transplant, advanced kidney disease, or on multiple medications should consult their doctor before drinking it regularly.
