How Ginkgo Biloba May Influence Blood Pressure

Ginkgo biloba has long been praised for its potential memory-boosting effects and circulatory benefits. It's one of the most widely used herbal supplements in the U.S. and Europe, often marketed as a natural way to support brain health, enhance energy, and even lower blood pressure. But when it comes to your heart and vascular health, especially if you're managing hypertension, it’s worth taking a closer look at the facts.

What Is Ginkgo Biloba?

Ginkgo biloba is derived from the leaves of the ginkgo tree, which has been used in traditional Chinese medicine for centuries. Today, it's commonly sold in tablet, capsule, and tea form. Many people take it for memory issues, age-related cognitive decline, or simply for general wellness.

However, despite its popularity, clinical evidence doesn’t support many of the health claims, especially when it comes to its effects on blood pressure.

Does Ginkgo Biloba Lower Blood Pressure?

Despite its reputation, there is no significant scientific evidence to show that ginkgo biloba lowers blood pressure in a meaningful way. According to the University of Michigan Health System, research has not proven it effective in treating hypertension or heart disease.

Some small studies suggest that ginkgo may slightly reduce blood pressure, but the effect is not strong or consistent enough to recommend it as a treatment. In fact, taking it when you're already on blood pressure medication could do more harm than good.

Why You Should Avoid Ginkgo If You’re Taking BP Medications

If you're on medication for high blood pressure, adding ginkgo to the mix can be risky. Dr. Guy L. Mintz, a cardiologist and director of Cardiovascular Health at North Shore University Hospital in New York, warns that ginkgo may cause blood pressure to drop too low when combined with certain medications. This is particularly concerning for older adults who might already be using the supplement for memory issues or age-related conditions like Alzheimer's disease.

According to Mount Sinai Health System:

• Ginkgo can interact negatively with antihypertensive drugs, such as nifedipine (Procardia), a common calcium channel blocker.

• Sudden drops in blood pressure could lead to dizziness, fainting, or worse falls and heart rhythm issues.

The University of Michigan Health System recommends avoiding ginkgo altogether if you're on blood pressure medication unless specifically advised by your healthcare provider.

Other Health Risks and Interactions to Know

The risks of ginkgo extend beyond blood pressure. One major concern is increased bleeding risk, especially when combined with certain medications or before surgical procedures.

Avoid ginkgo biloba if you’re taking or scheduled for:

• Antiplatelet therapy (e.g., aspirin)

• Anticoagulants (blood thinners like warfarin, Eliquis, or Xarelto)

• NSAIDs such as ibuprofen or naproxen

• Surgery (stop taking ginkgo at least one week prior)

Ginkgo may also interfere with:

• Anticonvulsants like carbamazepine (Tegretol) and valproic acid (Depakote), potentially reducing their effectiveness

• Medications for infections (e.g., HIV, tuberculosis)

• Treatments for depression, anxiety, asthma, high cholesterol, cancer, or autoimmune diseases

• Erectile dysfunction drugs and medications for psychiatric or neurological conditions

Pregnant individuals should also avoid ginkgo due to risks like excessive bleeding during delivery or premature labor, per the National Center for Complementary and Integrative Health.

What to Do Instead

If you're looking to manage blood pressure naturally, talk to your doctor about safer and evidence-backed alternatives. Lifestyle adjustments can play a big role, including:

• Reducing sodium intake (ideally under 1,500 mg per day)

• Regular cardiovascular exercise, like walking, swimming, or cycling

• Managing stress with techniques like meditation or yoga

• Eating more potassium-rich foods such as bananas, spinach, and sweet potatoes

While ginkgo biloba may seem like a harmless herbal remedy, its interactions with blood pressure medications and other treatments can be dangerous. If you're taking prescription drugs or managing a chronic health condition, always consult your healthcare provider before adding any supplement to your regimen.
