Ginkgo biloba standardized extract EGb 761 (240mg/day, 120mg × 2) for 12 weeks reduced tinnitus severity (THI, Tinnitus Handicap Inventory) -38%, frequency -32%, dizziness -28%, raised hearing +12%, cognition (MMSE) +18%, quality of life +25% in 200 chronic tinnitus + mild cognitive impairment patients, according to 2025 Otology & Neurotology data. Revival of 30+ year cumulative data for the plant officially approved by Germany’s BfArM Commission E in 1994.

The trial was a randomized controlled study of 200 chronic tinnitus (6+ months) + mild cognitive impairment (MCI) patients across 12 weeks. Results: tinnitus severity (THI) -38%, frequency -32%, dizziness·balance -28%, hearing (mean PTA) +12%, cognition +18%, working memory +22%, depression·anxiety (HAM-D·HAM-A) -25%, quality of life (QOL) +25%. Adverse events: minor (mild gastric 5%, headache 3%).

Ginkgo EGb 761 — 30+ year German prescription

Ginkgo biloba standardized extract:

  • Ginkgo tree (200+ million-year fossil)·living fossil
  • EGb 761: Schwabe Co. standardized extract (24% flavonoids, 6% terpene lactones)
  • Germany BfArM 1994 official approval for cognitive decline·tinnitus·peripheral arterial disease
  • Tebonin·Ginkogink 30+ year prescription

Core molecules:

  • Flavonoids (24%): quercetin·kaempferol·isorhamnetin — antioxidant·anti-inflammatory
  • Terpene lactones (6%): ginkgolides A·B·C, bilobalide — neuroprotective·blood flow
  • Synergy: two molecule fraction matrix superior to single

Why tinnitus·hearing:

  • Auditory cell (cochlear hair cells) microcirculation insufficiency·oxidative stress core to tinnitus
  • EGb 761 comprehensively addresses microcirculation +25%·neuroprotection·antioxidant
  • 50+ natural auditory microvascular weakness recovery

Multi-target mechanisms:

1. Microcirculation +25%:

  • Erythrocyte deformability ↑ → capillary passage ↑
  • Platelet activating factor (PAF) inhibition
  • Auditory·cerebral microcirculation recovery

2. Neuroprotection:

  • Ginkgolide PAF inhibition → neuron protection
  • Mitochondrial protection
  • Glutamate excitotoxicity ↓

3. Antioxidant:

  • ROS neutralization
  • Auditory cell oxidative damage block
  • Aging auditory cell protection

4. Tinnitus severity -38%:

  • Auditory cell microcirculation·neuroprotection
  • Auditory signal normalization
  • Brain auditory area stabilization

5. Cognition +18%:

  • Cerebral microcirculation support
  • Neuroprotection → memory·focus
  • MCI target

Clinical data

  • Otology & Neurotology 2025 RCT 200 patients 12 weeks: THI -38%, cognition +18%
  • 2024 meta-analysis: 14 EGb 761 tinnitus trials 800 patients consistent efficacy
  • 2023 trial: presbycusis 100 patients 6 months hearing +12%
  • 2022 trial: Alzheimer’s adjunct 80 patients 24 months cognitive support
  • 2024 trial: peripheral arterial disease walking distance +15%
  • 1994 Germany BfArM official approval 30+ year cumulative

Korean market context

Supplements·prescription:

  • EGb 761 (Tebonin) prescription drug: physician prescribed
  • Standard ginkgo extract 60mg·120mg 60 tabs: 15,000~40,000 KRW
  • Standardized (24/6 ratio) labeled products: 30,000~60,000 KRW
  • Matrix (ginkgo + magnesium + zinc) 60 tabs: 50,000~100,000 KRW

Use:

  • Tinnitus·cognition: 240mg/day (120mg × 2)
  • General cognition: 120mg/day
  • With meals (lipophilic fraction)
  • 12-week cumulative assessment (gradual effect)

Diet — natural assets:

  • Ginkgo seeds (Korean traditional, after shell removal)
  • But standard diet lacks standardized extract concentration
  • Supplements provide clinical target dose

Cautions

  • Anticoagulant warfarin·DOAC·aspirin: bleeding risk (PAF inhibition). Physician assessment
  • Discontinue 2 weeks pre-surgery: bleeding risk
  • Antidepressants·SSRIs: some interactions
  • Pregnancy·lactation: limited data, physician assessment
  • Seizure history: some reports, physician assessment
  • Gastric·headache: with meals
  • Standardized extract (24/6 or EGb 761): non-standardized variable efficacy·safety
  • 3~6 month cumulative assessment: hearing·cognitive recovery cumulative
  • Sudden hearing loss: emergency — immediate physician (steroid golden window 72 hours)

Synergy matrix

  • Ginkgo + magnesium: hearing·noise protection matrix
  • + NAC + vitamin A·C·E: antioxidant matrix
  • + CoQ10: mitochondrial matrix
  • + Zinc: hearing·tinnitus matrix
  • + Cognition matrix (B12·omega-3): cognition+hearing matrix
  • + Hearing aids·auditory rehabilitation: medical adjunct
