Homemade St. John’s Wort Tincture and Extract Recipe using Food Grade Ethanol
St. John’s Wort is a flowering botanical herb known for its bright yellow blossoms, perforated-looking leaves, and long history in traditional herbal preparations. A homemade St. John’s Wort tincture or extract turns the fresh flowering tops into a liquid preparation that is easier to measure, blend, and store for educational and botanical projects.
This guide explains how to make a St. John’s Wort tincture using fresh Hypericum perforatum flowering tops and an 80 proof ethanol-water menstruum prepared from USDA Certified Organic 200 Proof Food Grade Ethanol. St. John’s Wort is not best handled with straight 200 proof ethanol. This recipe uses a lower-proof menstruum because fresh flowering tops bring both alcohol-friendly and water-friendly compounds into the extraction.
What is St. John’s Wort?
St. John’s Wort (Hypericum perforatum) is a perennial flowering herb recognized for its bright yellow flowers and leaves marked with tiny translucent dots that look like perforations when held to the light. It is native across parts of Europe, Asia, and North Africa and has become widely naturalized in many other temperate regions.
For tincture making, the relevant plant part is the fresh flowering top. This includes the flowers, buds, and tender leafy aerial parts collected during active bloom. The fresh plant is preferred for this recipe because the flowering tops are the most valued material for traditional St. John’s Wort tincture preparation.
St. John’s Wort contains compound groups often discussed in extraction, including naphthodianthrones such as hypericin and pseudohypericin, phloroglucinols such as hyperforin, flavonoids, xanthones, tannins, and phenolic acids. Because these compound groups do not all behave the same way in alcohol, this recipe uses an ethanol-water menstruum rather than straight 200 proof ethanol.
Why Make St. John’s Wort Tincture or Extract?
A St. John’s Wort tincture gives you a liquid way to work with a fresh flowering herb that is seasonal and time-sensitive. The flowering tops are usually gathered when the plant is in bloom, and tincturing is one way to preserve that botanical material in a compact, shelf-stable format.
St. John’s Wort has a long history in traditional botanical preparations. This historical context is included for background only and should not be read as a medical claim.
For herbalists, apothecaries, and DIY makers, St. John’s Wort is a useful example of why plant state matters. Fresh flowering tops are preferred in this recipe, while dried material is not treated as the default choice.
Where Does St. John’s Wort Grow?
St. John’s Wort grows in sunny, well-drained environments such as meadows, grasslands, field edges, roadsides, and disturbed open areas. It has naturalized widely outside its native range and can be considered weedy or invasive in some regions.
If sourcing fresh flowering tops, correct identification and clean harvest location are important. Avoid roadsides, sprayed fields, industrial areas, treated landscapes, and locations exposed to runoff. If purchasing rather than harvesting, choose fresh or freshly processed flowering tops from a reputable herb supplier, grower, or apothecary.
Sourcing and Selecting Quality St. John’s Wort
Choose St. John’s Wort flowering tops from a reputable herb supplier, apothecary, cultivated garden, responsible foraging location, or fresh botanical grower. The material should be identified as Hypericum perforatum. Correct identification matters because not every yellow-flowering plant in the field is St. John’s Wort.
Fresh flowering tops should have bright yellow flowers, healthy green leaves, and a clean herbal aroma. Leaves should show the small translucent dots associated with Hypericum perforatum. Avoid wilted, moldy, discolored, dirty, or stale plant material.
Fresh material is preferred for this recipe. If using dried St. John’s Wort, the finished tincture may not match the fresh-flowering-top preparation described here. For the most faithful version of this recipe, use fresh flowering tops collected during active bloom.
Preparing St. John’s Wort for Extraction
Inspect the fresh flowering tops and remove insects, damaged stems, woody material, and debris. Rinse only if necessary, then allow any surface moisture to dry fully before maceration. Extra surface water can change the finished menstruum strength and may reduce extraction consistency.
Lightly chop the fresh flowering tops before adding them to the jar. The goal is to increase surface area while keeping the herb in a coarse, strainable form. Do not grind the fresh herb into a paste, since very fine material can be harder to strain and may produce more sediment.
Choosing the Right Menstruum
The menstruum is the liquid used to extract compounds from the plant material. For St. John’s Wort flowering tops, the recommended menstruum is 80 proof, or 40% ABV.
This strength gives the recipe both ethanol and water. Ethanol helps extract alcohol-friendly constituents such as hypericin-related naphthodianthrones, hyperforin-related phloroglucinols, flavonoid aglycones, and other less water-friendly compounds. Water helps support extraction of flavonoid glycosides, tannins, phenolic acids, and other water-friendly plant constituents.
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 80 Proof Works for St. John’s Wort
80 proof, or 40% ABV, works well for fresh St. John’s Wort flowering tops because it provides both ethanol and water in the same menstruum. This is useful for a flowering herb that contains a mixed compound profile rather than only oil-forward or resin-forward 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 less water-friendly constituents. An 80 proof menstruum is a practical target for fresh Hypericum perforatum flowering tops.
Recommended Ingredient-to-Menstruum Ratio
The recommended St. John’s Wort tincture ratio is 1:2 using fresh flowering tops. That means 1 part fresh St. John’s Wort by weight to 2 parts finished menstruum by volume. For an 8 fl oz batch, use 4 oz fresh flowering tops by weight.
| Ingredient State | Plant Part | Ratio | Amount for 8 fl oz Menstruum | Target ABV |
|---|---|---|---|---|
| Fresh | Flowering tops | 1:2 | 4 oz fresh flowering tops by weight | 40% ABV, 80 proof |
The ratio applies to finished menstruum volume, not ethanol volume alone. For this recipe, the finished 8 fl oz menstruum is made from 3.2 fl oz of 200 proof ethanol plus 4.8 fl oz of water.
How to Prepare 8 fl oz of 80 Proof Menstruum
To make 8 fl oz of 80 proof menstruum from 200 proof food grade ethanol, combine 3.2 fl oz of 200 proof ethanol with 4.8 fl oz of water. This produces 8 fl oz of 40% ABV menstruum before the fresh St. John’s Wort is added.
| Final Menstruum Volume | Target Strength | 200 Proof Food Grade Ethanol | Water |
|---|---|---|---|
| 8 fl oz | 80 proof, 40% ABV | 3.2 fl oz | 4.8 fl oz |
Measure carefully and mix the ethanol and water before adding the menstruum to the fresh flowering tops. 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 St. John’s Wort 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 when working with fresh chopped flowering tops. Let the bottle sit upright and decant carefully if you want a clearer pour.
