Black Walnut (Juglans nigra) - Leaf, Liquid Extract Tincture (External Use Only)

This is an alcohol-based liquid extract (tincture) of the dried leaf of Juglans nigra, the Eastern black walnut, a North American tree of the Juglandaceae family. This product is intended for external (topical) use only - it is not to be taken internally. The leaf naturally contains tannins and juglone, a compound characteristic of walnuts.

Botanical name: Juglans nigra L. (Eastern black walnut; Juglandaceae)
Plant part: Dried leaf
Intended use: External use only - as a diluted skin or hair rinse, wash or compress. Do not swallow.
Also known as: black walnut, Eastern black walnut, American walnut
Extract type: Alcohol tincture (cold maceration in organic alcohol)
Other ingredients: Organic alcohol, vegetable glycerin, crystal clear purified water
Origin: Leaf responsibly sourced (USA); prepared in the USA. Gluten free.

This is the black walnut leaf. It is a different part from our Black Walnut Hull (the same tree), and a different plant from English walnut (Juglans regia) and Butternut (Juglans cinerea), which we sell separately - and it is the leaf, not the edible nut. Please read the external-use safety notes below.

External use only - important safety information, please read before use

For external (topical) use only. Do NOT take this product internally.

Patch test first: black walnut leaf contains juglone and tannins, which can irritate the skin - apply a small diluted amount to a small area first and wait 24 hours; stop use if any redness, itching or irritation occurs.
Contains alcohol: this tincture contains organic alcohol, which can sting or dry the skin - dilute it before use and do not apply to broken skin.
Staining: juglone is a natural brown dye and can stain skin, hair, nails and fabric - handle with care.
Where not to apply: do not apply to broken, irritated or sensitive skin, and keep it away from the eyes and mucous membranes.
Tree-nut allergy: black walnut is a tree-nut plant - do not use it, even on the skin, if you are allergic to walnuts or tree nuts.
Pregnancy / nursing: if you are pregnant or breastfeeding, ask a qualified healthcare practitioner before external use.
Keep out of reach of children; not for use on infants or young children. If irritation persists, discontinue use and consult a practitioner.

Frequently Asked Questions about Black Walnut Extract

What is Black Walnut (Juglans nigra) leaf extract, and how is it used?

Black walnut is a liquid extract of the dried leaf of Juglans nigra, the Eastern black walnut, a North American tree of the Juglandaceae family. This product is for EXTERNAL (topical) use only - it is not to be taken internally. This alcohol tincture is used as a diluted skin or hair rinse, wash or compress. The leaf naturally contains tannins (astringent compounds) and juglone, a compound characteristic of walnuts. Two things are worth knowing: this is the black walnut leaf (Juglans nigra), a different part from our Black Walnut Hull (the same tree) and a different plant from English walnut (Juglans regia) and Butternut (Juglans cinerea), which we sell separately - and it is the leaf, not the edible nut; and because it contains juglone and tannins (and this version contains alcohol) that can irritate or stain the skin, please read the external-use safety notes below.

What is the difference between the tincture and alcohol-free versions?

Both are external liquid extracts of the same Juglans nigra leaf; only the solvent differs. This tincture uses organic alcohol with vegetable glycerin and water; the alcohol can sting or dry the skin, so dilute it well before external use. The alcohol-free version is a glycerite made with vegetable glycerin and crystal clear water instead, gentler on the skin for those who prefer to avoid alcohol. Both are for external use only. Choose the tincture for a traditional alcohol-extracted format; choose the glycerite for a gentler feel. The botanical inside is identical. Please follow the external-use safety notes for both.

Is black walnut leaf the same as the hull, English walnut or butternut?

No - several walnut products are easy to mix up, so it helps to be clear. This is the leaf of Juglans nigra, the black walnut. The black walnut hull (the green outer covering of the nut) is a different part of the same tree, which we sell separately as Black Walnut Hull - the hull is especially rich in juglone. English walnut is a different species, Juglans regia (the common edible walnut), and we offer its leaf separately. Butternut, or white walnut, is Juglans cinerea, and we offer its inner bark. All are in the walnut family (Juglandaceae) and share tree-nut and juglone characteristics, but they are different parts or species. And note this is the leaf, not the edible walnut kernel. We label ours clearly as black walnut (Juglans nigra) leaf so it is not confused with the hull, with English walnut, or with butternut.

How do I use Black Walnut leaf extract externally?

This product is for external use only - do not swallow it. Shake well first, then dilute it in water before use (for example as a skin or hair rinse, wash or compress); because it contains alcohol, dilute it well so it does not sting or dry the skin. Always patch test first: apply a small diluted amount to a small area of skin and wait 24 hours before wider use. Avoid broken, irritated or sensitive skin, and keep it away from the eyes. Note that juglone can stain skin, hair, nails and fabric, so handle with care. Please read the external-use safety information below before use. Store in a cool, dry place away from direct light.

Is Black Walnut leaf safe? External-use safety information.

Please read this carefully. This product is for external (topical) use only - do NOT take it internally. Skin irritation: black walnut leaf contains juglone and tannins, and this version contains alcohol, which together can irritate the skin, so always patch test first and stop use if redness, itching or irritation occurs; do not apply it to broken, irritated or sensitive skin or near the eyes. Staining: juglone is a natural brown dye and can stain skin, hair, nails and fabric. Tree-nut allergy: black walnut is a tree-nut plant, so do not use it, even on the skin, if you are allergic to walnuts or tree nuts. Pregnancy and nursing: if you are pregnant or breastfeeding, ask a qualified healthcare practitioner before external use. Keep out of reach of children and do not use it on infants or young children. If irritation persists, discontinue use and consult a qualified healthcare practitioner. This tincture contains alcohol and should be stored in a cool, dark place.

ETHICALLY SOURCED, NATURAL INGREDIENTS 100% natural

Our Black Walnut (Juglans Nigra) Leaf is selected from regions with optimal growing conditions to support a high concentration of active constituents. We work only with trusted suppliers and focus on sourcing clean, well-preserved botanical material suitable for high-quality liquid extraction.

As a solvent, we use alcohol to preserve the integrity of the extract and support a clean extraction process.

To verify botanical identity and ensure consistency, all raw materials are tested in our laboratory using established analytical techniques. These include High-Performance Thin-Layer Chromatography (HPTLC) for plant authentication and fingerprinting, or Fourier-Transform Infrared Spectroscopy (FTIR) and other in-house methods. Our approach is guided by relevant standards such as those of the USP and Ph. Eur., ISO 17025 and cGLP, allowing us to maintain rigorous quality control, ensuring the material meets our specifications for identity, purity and composition.

METICULOUS EXTRACT PREPARATION Small-Batch

Hawaii Pharm determines the optimal herb-to-menstruum ratio for each botanical. For alcohol-based extracts, we use a carefully balanced alcohol blend to ensure maximum extraction of active compounds while preserving the plant's natural integrity.
Our master herbalists analyze each batch and adjust extraction parameters as needed, ensuring consistent quality despite natural variations in botanical sources.
The result is a potent, stable liquid extract that captures the full spectrum of the botanical's benefits.

COMPREHENSIVE LABORATORY TESTING Lab-Tested

Every batch undergoes multiple quality assurance tests including:

Organoleptic evaluation (color, consistency, aroma)
FTIR and/or HPTLC spectral analysis for identity confirmation
Microbiological testing (total plate count, E. coli, coliforms)
Yeast and mold screening
Alcohol content verification
