Homemade Ginkgo Biloba Tincture and Extract Recipe
Ginkgo biloba is a distinctive botanical ingredient known for its fan-shaped leaves and long history of cultivation. A homemade ginkgo biloba tincture or extract turns dried ginkgo leaf into a liquid preparation that is easier to measure, blend, and store for educational herbal projects.
This guide explains how to make a ginkgo biloba tincture using dried Ginkgo biloba leaf and a 100 proof ethanol-water menstruum prepared from USDA Certified Organic 200 Proof Food Grade Ethanol. Ginkgo leaf is not best handled with straight 200 proof ethanol. A 100 proof menstruum provides both ethanol and water, which is better suited to extracting the leaf’s mixed compound profile.
What is Ginkgo Biloba?
Ginkgo biloba (Ginkgo biloba) is a deciduous tree recognized for its fan-shaped leaves and unusual botanical history. It is often described as a living fossil because ginkgo represents a very old lineage of trees with no close living relatives.
For tincture making, the relevant plant part is the leaf. The project ingredient reference specifies yellow ginkgo leaf for extraction. Ginkgo seeds have their own separate traditional context in Chinese herbal practice, but this recipe is not a seed preparation and the seeds should not be substituted for the leaf.
Ginkgo leaf contains flavonol glycosides, terpene lactones such as ginkgolides and bilobalide, organic acids, polysaccharides, and other compounds. Because those compounds do not all behave the same way in alcohol, this recipe uses a 100 proof ethanol-water menstruum rather than straight 200 proof ethanol.
Why Make Ginkgo Biloba Tincture or Extract?
A ginkgo biloba tincture gives you a liquid way to work with dried ginkgo leaf. Dried leaves can be bulky and slow to infuse directly, while a tincture keeps the botanical preparation in a compact, shelf-stable form.
Ginkgo has a long cultural history in China, and ginkgo seed appears in Traditional Chinese Medicine under the name bai guo. Ginkgo leaf preparations are more modern by comparison. This historical context is included for background only and should not be read as a medical claim.
For herbalists, apothecaries, and DIY makers, ginkgo leaf is a useful example of why proof selection matters. A balanced ethanol-water menstruum can support extraction of both alcohol-friendly and water-friendly leaf constituents.
Where Does Ginkgo Grow?
Ginkgo is native to China and is now widely planted around the world as an ornamental and street tree. It is valued for its distinctive leaf shape, strong urban tolerance, and bright yellow autumn color.
For tincture making, purchased dried ginkgo leaf is usually more practical than harvesting from landscape trees. Landscape trees may be exposed to road runoff, lawn chemicals, pollutants, or unknown growing conditions. Use properly identified botanical material from a reputable herb supplier whenever possible.
Sourcing and Selecting Quality Ginkgo Leaf
Choose ginkgo leaf from a reputable herb supplier, apothecary, or botanical ingredient seller. The material should be identified as Ginkgo biloba leaf. The project reference specifies yellow leaf, so look for clean, properly dried leaf material that has been handled for botanical preparation.
Good dried ginkgo leaf should be clean, dry, and free from mold, excess dust, insect damage, or musty odor. Leaf pieces may vary in size, but they should not smell stale, damp, or contaminated.
Avoid using unknown leaves gathered from public spaces, roadsides, or treated landscapes. Correct identification and clean handling matter because the finished tincture can only reflect the quality of the starting material.
Preparing Ginkgo Leaf for Extraction
Dried ginkgo leaf should be cut or lightly crumbled before extraction so the menstruum can reach more surface area. If the leaf is already cut and sifted, it can usually be used as-is.
Avoid grinding the leaf into a fine powder unless you are prepared for slower straining and more sediment. Powdered leaf can absorb more menstruum and may produce a cloudy finished tincture. Cut leaf is usually easier for home tincture preparation.
Choosing the Right Menstruum
The menstruum is the liquid used to extract compounds from the plant material. For ginkgo leaf, the recommended menstruum is 100 proof, or 50% ABV.
This strength gives the recipe both ethanol and water. Ethanol helps extract alcohol-friendly compounds such as terpene lactones and flavonol aglycones, while water helps support extraction of flavonol glycosides, polysaccharides, organic acids, and other water-friendly components.
Starting with USDA Certified Organic 200 Proof Food Grade Ethanol gives you a clean high-proof starting point that can be diluted accurately to the target strength. For more help with dilution, see this guide to dilute your 200 proof ethanol for tincture recipes.
Why 100 Proof Works for Ginkgo Leaf
100 proof, or 50% ABV, works well for ginkgo leaf because it gives the finished menstruum an even balance of ethanol and water. This is useful for a leaf that contains both alcohol-friendly and water-friendly constituents.
Using 200 proof ethanol undiluted would make the extraction too alcohol-heavy for this ingredient. Using a much lower proof could reduce the ethanol strength needed for some of the leaf’s less water-friendly compounds. A 100 proof menstruum is a practical middle ground for dried ginkgo leaf.
Recommended Ingredient-to-Menstruum Ratio
The recommended ginkgo leaf tincture ratio is 1:5. That means 1 part dried ginkgo leaf by weight to 5 parts finished menstruum by volume. For an 8 fl oz batch, use 1.6 oz dried ginkgo leaf by weight.
| Ingredient State | Plant Part | Ratio | Amount for 8 fl oz Menstruum | Target ABV |
|---|---|---|---|---|
| Dried | Leaf | 1:5 | 1.6 oz dried ginkgo leaf by weight | 50% ABV, 100 proof |
The ratio applies to finished menstruum volume, not ethanol volume alone. For this recipe, the finished 8 fl oz menstruum is made from 4 fl oz of 200 proof ethanol plus 4 fl oz of water.
How to Prepare 8 fl oz of 100 Proof Menstruum
To make 8 fl oz of 100 proof menstruum from 200 proof food grade ethanol, combine 4 fl oz of 200 proof ethanol with 4 fl oz of water. This produces 8 fl oz of 50% ABV menstruum before the ginkgo leaf is added.
| Final Menstruum Volume | Target Strength | 200 Proof Food Grade Ethanol | Water |
|---|---|---|---|
| 8 fl oz | 100 proof, 50% ABV | 4 fl oz | 4 fl oz |
Measure carefully and mix the ethanol and water before adding the menstruum to the ginkgo leaf. Use clean water suitable for food preparation. When ethanol and water are mixed, the liquid may warm slightly and the final volume can contract a little. For small home tincture batches, careful measuring remains a practical approach.

Storage Best Practices
Store finished ginkgo biloba tincture in amber or other UV-protective glass, away from heat and direct sunlight. A cool cabinet or pantry is a good choice. Keep the bottle tightly sealed to reduce evaporation and limit air exposure.
Clear glass can be used during maceration if the jar is kept away from sunlight. For finished storage, amber glass is preferred. Some sediment may settle in the bottle over time, especially if the leaf was crushed finely. Let the bottle sit upright and decant carefully if you want a clearer pour.

Final Thoughts
Ginkgo biloba is a useful example of why leafy botanical tinctures should not automatically be made with straight 200 proof ethanol. The leaf contains both water-friendly and alcohol-friendly compound groups, so a 100 proof ethanol-water menstruum is a better fit for this preparation.
For the most practical home recipe, use dried ginkgo leaf at a 1:5 ratio with 8 fl oz of finished 100 proof menstruum. With clean leaf material, careful dilution, and proper storage, homemade ginkgo biloba tincture can be a useful addition to educational and botanical extract projects.
