Black Walnut Hulls Juglans nigra

Botanical Information

Common Names: Black Walnut

Botanical Name: Juglans nigra

Family: Juglandaceae

Description: Large deciduous tree with pinnate leaves, deeply furrowed dark bark, and green spherical fruits that blacken as they age. The green hull (pericarp) around the nut is the primary medicinal part.

History & Tradition

• Traditional North American and European remedy for intestinal parasites and fungal infections.
• Used externally for ringworm and skin conditions.
• Known for its strong, dark staining juice and potent astringent/antiseptic properties.

Cultivation & Parts Used

Parts Used: Green hulls (fresh or dried); sometimes leaf.

Growing Conditions: Deep, fertile soils; full sun; temperate climates.

Collection: Hulls harvested while green and still soft, before they fully blacken and decay.

Doctrine of Signatures

The dark, inky, strongly staining hull suggests deep cleansing of hidden, tenacious issues (like parasites and fungi). The tough shell and strong tree reflect boundary, protection, and inner fortification.
