Ginkgo biloba (Ginkgo biloba): what it does, how to use it safely
Estimated reading time: 12 minutes
Key Takeaways
- Today we are looking at Ginkgo biloba, a living fossil of a tree that shows up in both traditional East Asian medicine and modern clinical research.
- People use standardized ginkgo leaf extracts for memory support, healthy circulation, and antioxidant protection.
- It seems to work by improving microcirculation and calming platelet stickiness, plus it offers antioxidant effects.
- One heads-up, ginkgo can increase bleeding risk, especially with blood thinners.

A small sensory moment
On a breezy day, ginkgo's fan-shaped leaves make a soft clapping sound that feels a bit like a slow applause. It is an ancient kind of calm. That quiet longevity is part of why people reach for ginkgo when they want steadier memory and better flow.
Traditional Uses
Traditional Chinese Medicine: Historically, the seeds were used in small, carefully prepared amounts for cough and phlegm. Modern TCM and integrative practice lean more on the leaves for circulation and brain health. Important safety note, raw or unprocessed seeds are toxic and should not be used at home.
Ayurveda: Not a classical Ayurvedic herb. In modern practice, some clinicians use standardized leaf extract for "vata" type memory and circulation concerns, but this is an adoption rather than a traditional entry.
Unani and regional folk use: Limited classical use. In East Asia, roasted seeds appear in cuisine and older texts. Again, this is not recommended for self-care due to toxicity risk.
Overlap and differences: Most modern benefits center on the leaf's effects on blood flow and oxidation control. The ancient seed use does not translate well to contemporary self-care.
Modern Research
- Strong to moderate: Vascular support and microcirculation. Standardized extracts like EGb 761 can modestly improve peripheral and cerebral blood flow, partly by antagonizing the platelet activating factor receptor. In daily life, that may mean warmer hands and a touch more mental clarity in some people.
- Moderate: Cognitive support in mild cognitive impairment and early dementia. Trials using 120 to 240 mg per day show small improvements in memory and executive function. Results are not dramatic and do not stop disease progression.
- Preliminary to mixed: Anxiety, mood, tinnitus, and vertigo. Some small studies suggest mild benefit, while others do not.
- Unknowns: Which subgroups respond best, ideal duration beyond 6 to 12 months, and how it compares head to head with standard drugs in different conditions.
Safety, Dosage and Effective DRV
Standardized extract (for example, EGb 761, typically 24 percent flavone glycosides and 6 percent terpene lactones)
- General wellness: 120 to 240 mg daily, divided twice or three times
- Therapeutic ranges used in studies: 120 to 240 mg daily
- More is not better. Higher doses tend to raise side effect risk without clear added benefit.
Avoid or use only with medical guidance if you:
- Take blood thinners or antiplatelet medicines (aspirin, clopidogrel, warfarin, DOACs)
- Have a bleeding disorder or low platelets
- Have surgery scheduled in the next 1 to 2 weeks (stop ginkgo earlier if advised)
- Are pregnant, especially in the third trimester, or breastfeeding
- Have epilepsy or a seizure history
Interactions to know:
- Anticoagulants and antiplatelets, higher bleeding risk
- SSRIs or other antidepressants, rare reports of serotonin-related effects
- Antiepileptics, case reports of altered seizure threshold
- Diabetes medications, possible changes in blood sugar response
Seed warning: Ginkgo seeds are toxic and are not a safe substitute for leaf extract.
Friendly disclaimer: General info only; check with a qualified clinician for personal advice.
Active Compounds, explained simply
- Flavonoids, such as quercetin and kaempferol. These are antioxidants that mop up reactive oxygen species, which can reduce everyday oxidative wear and tear on cells.
- Ginkgolides, especially A, B, and C. These block the platelet activating factor receptor. In plain terms, platelets are a little less sticky, so microcirculation improves.
- Bilobalide. A terpene that seems to protect nerve cells and steady cell signaling.
Think of ginkgo's compounds as a traffic manager for tiny blood vessels, with a side gig as a cleanup crew for cellular stress.
Practical Effects and Applications
Short term (days to weeks): Gentle support for blood flow and antioxidant tone. Some people notice less coldness in fingers and toes.
Longer term (8 to 12 weeks or more): Modest help with memory and day to day cognitive tasks in older adults or those with early decline. Not a cure, more like a soft assist.
- Physiological: Improves microcirculation, reduces platelet clumping, supports endothelial function.
- Psychological: May slightly support alertness and mood in some users, although results vary. See stress support options
Synergy ideas, with caution:
- Antioxidants, such as vitamin C and E, for oxidative stress balance
- Adaptogens for overall brain resilience, ashwagandha rhodiola tongkat ali but avoid any herb that also thins blood
Who It's Probably Best For
- Adults looking for gentle cognitive support during aging
- People with cold hands and feet related to poor microcirculation
- Those with intermittent claudication who are working with a clinician
- Adults seeking antioxidant support who are not on blood thinners
- Not ideal for anyone with a bleeding risk, upcoming surgery, or complex polypharmacy
Myth vs Fact
Myth: Ginkgo cures Alzheimer's disease.
Fact: It may modestly support cognition in some people, but it does not cure or halt neurodegeneration. Larger trials show mixed outcomes.
Why this myth persists: Early promising studies and word of mouth.
Myth: Natural means safe for everyone.
Fact: Ginkgo can raise bleeding risk and interact with common medicines. Natural does not automatically mean risk free.
Why this myth persists: Long cultural use and over-the-counter availability.
Myth: You will feel sharper the first day you take it.
Fact: Benefits, when they occur, usually take weeks of steady use.
Why this myth persists: Marketing and occasional placebo effects.

How to Use
Standardized extract capsules or tablets
- Look for 24 percent flavone glycosides and 6 percent terpene lactones
- Take 120 to 240 mg per day with food, split into two or three doses
- Give it at least 8 weeks before judging effects
Liquid extract or tincture
- Use products that specify equivalent standardized content
- Typical range is what matches 120 to 240 mg of standardized extract daily
Tea or whole leaf
- Not equivalent to standardized extracts used in research
- If you still want a tea, steep 1 to 2 teaspoons dried leaf in hot water for 10 minutes. Expect mild bitterness. Do not rely on tea for clinical goals.
Taste tips
- Pair with orange peel or a slice of fresh ginger to soften the astringency
