- Safety: Ginkgo Biloba thins the blood. Do not combine it with aspirin, warfarin, or ibuprofen without consulting a doctor, as it significantly increases bleeding risk. Stop taking it 2 weeks before surgery.
- Effectiveness: Clinical trials show Ginkgo is most effective for tinnitus caused by vascular insufficiency (poor blood flow) in the brain. It is less effective for tinnitus caused by noise-induced hearing loss or ear trauma.
- Key Benefit: The active compounds (flavonoids and terpenoids) dilate capillaries and reduce blood viscosity, delivering more oxygen to the auditory nerve and cochlea.
The ringing is relentless. It isn’t a sound from the outside world; it is a phantom noise generated by a starving auditory nerve. You have tried white noise machines. You have tried ignoring it. Now you are looking at herbal shelves.
Ginkgo Biloba is one of the oldest tree species on earth. Its leaves have been used for thousands of years to improve memory and circulation. But can a leaf silence the ringing in your ears? The answer depends entirely on why your ears are ringing.
Researchers believe the mechanism is hemodynamic. I summarized the pharmacological action of EGb 761, the standardized Ginkgo extract. Evidence indicates that ginkgo biloba’s benefits for tinnitus are mainly vascular, working by “unclogging” the tiny blood vessels that supply the ear.
Physiologically Speaking: Feeding The Cochlea
The inner ear is an energy hog. It has no backup blood supply (no collateral circulation). It relies on a single, tiny artery (the labyrinthine artery) to deliver oxygen. If this artery narrows due to age, stress, or plaque, the cochlea suffocates.
Physiologically speaking, a suffocating cochlea misfires. These misfires are interpreted by the brain as ringing. Ginkgo Biloba increases nitric oxide levels, which relaxes the blood vessel walls (vasodilation). It also makes blood less sticky (anti-platelet effect). This allows blood to squeeze into the microscopic capillaries of the ear, restoring oxygen supply and calming the nerve.
A direct comparison reveals the target audience. If your tinnitus is “somatic” (caused by jaw clenching or neck tension), Ginkgo won’t help much. If your tinnitus is “vascular” or “cerebrovascular” (associated with dizziness, memory issues, or cold hands/feet), Ginkgo is highly relevant. A study in the Neuropsychiatric Disease and Treatment journal found that standardized Ginkgo extract was as effective as the drug Pentoxifylline for treating sudden hearing loss and tinnitus.

5 Clinical Methods To Test Efficacy
1. The 12-Week Trial
Ginkgo is slow. It takes time to remodel microcirculation. Do not expect silence in 3 days. Commit to a 12-week trial. If there is no change in volume or pitch by week 12, it is not the right tool for your type of tinnitus.
Pro-Tip: Keep a symptom diary rating your ringing from 1-10 daily to track subtle improvements.
2. The Dosage Floor
Most studies showing failure used low doses (40mg). Studies showing success typically used 120mg to 240mg per day. You need to hit this therapeutic threshold to see vasodilation effects.
Pro-Tip: Split the dose (e.g., 120mg morning, 120mg afternoon) to keep blood levels stable.
3. Standardized Extract Only
Raw Ginkgo leaves contain ginkgolic acids, which are toxic and allergenic. Only buy extracts labeled “Standardized to 24% Flavone Glycosides and 6% Terpene Lactones.” This ensures the toxin has been removed and the medicine is present.
Pro-Tip: Look for the code “EGb 761” on the label if possible.
4. Stack with Magnesium
Magnesium protects the nerves from excitotoxicity (over-firing). Ginkgo improves blood flow. Together, they protect the hardware (nerves) and improve the fuel supply (blood). This is a synergistic pairing for ear health.
Pro-Tip: Use Magnesium Glycinate or Threonate for better brain absorption.
5. Monitor Blood Pressure
Ginkgo can slightly lower blood pressure. If your tinnitus gets worse when you stand up quickly, you might have low blood pressure already. Monitor closely.
Doctor’s Note: If you feel dizzy, stop immediately.
Stacking Your Strategy For Silence
To make this work 20% better, stack your Ginkgo Biloba with CoQ10 (Ubiquinol).
Ginkgo delivers the fuel (oxygen/glucose) to the ear. CoQ10 helps the mitochondria inside the ear cells use that fuel efficiently. The inner ear has one of the highest metabolic rates in the body. By optimizing both delivery and utilization, you give the auditory cells the best chance to repair and stop screaming.
Safety & Precautions
1. Bleeding Risk
Ginkgo inhibits platelet aggregation (clotting).
Safety Note: If you get frequent nosebleeds or have a surgery planned, Ginkgo is contraindicated.
2. Seizure Threshold
Ginkgo seeds contain a neurotoxin (ginkgotoxin). While leaves have less, high doses can theoretically lower the seizure threshold.
Caution: Avoid if you have epilepsy or take anti-seizure medication.
3. Diabetes Interaction
Ginkgo may affect insulin secretion.
Heads Up: Monitor blood sugar closely if you are diabetic; you might need to adjust meds.
4. “Raw” Leaf Danger
Never eat fresh Ginkgo leaves or seeds from a tree. They are toxic.
Doctor’s Note: Only use processed, encapsulated supplements.
5. Headache/Dizziness
Paradoxically, the rush of blood to the brain can cause headaches initially.
Warning: Start with a lower dose (60mg) and titrate up to avoid the “Ginkgo Headache.”
5 Common Myths vs. Facts
Myth 1: It cures all tinnitus.
Fact: It helps vascular tinnitus. It does little for noise-induced damage (dead hair cells) or somatic tinnitus (jaw issues). It is a circulation booster, not a magic eraser.
Myth 2: It works immediately.
Fact: It takes 4 to 6 weeks to see significant changes in microcirculation. Patience is mandatory.
Myth 3: Any brand works.
Fact: The supplement industry is rife with adulteration. Many “Ginkgo” supplements are just quercetin or rutin fillers. Buy reputable, standardized brands.
Myth 4: It prevents Alzheimer’s.
Fact: Large studies (like the GEM study) showed it did not prevent Alzheimer’s, but it did improve cognition in those with vascular dementia/insufficiency.
Myth 5: It’s just a placebo.
Fact: While some studies are mixed, meta-analyses confirm it outperforms placebo significantly for tinnitus related to cerebral insufficiency and dementia.
The Bottom Line
Blood flow quiets the noise.
My analysis concludes that for the efficiency-minded user, Ginkgo Biloba is a viable first-line trial for tinnitus, provided you fit the profile (vascular issues, age-related decline). It addresses the root cause of “starving” ear cells.
The key factor here is quality. Make sure to get the standardized extract. For a clinical-strength effect that reaches the inner ear, go for 120mg of EGb 761 Standardized Extract twice a day. Pair it with magnesium to relax the nerves while the ginkgo helps open up the blood vessels.
