Black Walnut

Energetics

Cold, dry, bitter, highly astringent.

Constitutional Fit (Ayurveda)

Best suited to Kapha and Pitta constitutions — its cold, drying, astringent nature counters excess moisture and heat. Not indicated for Vata types prone to dryness, unless used briefly and in small doses.

TCM Pattern

Associated with Damp-Heat, particularly in the digestive and lower burner — its astringent, drying quality clears damp stagnation and discourages parasitic or fungal overgrowth.

Tissue States

• Western (Matthew Wood): Indicated for Damp and Lax tissue — tightens what has become too loose, dries what has become too wet.
• Ayurvedic (Dhatu): Acts on Rasa and Rakta (plasma and blood), clearing ama (toxic buildup) from the digestive and lymphatic terrain.

Summary

A cold, bitter, highly astringent remedy. Black Walnut Hull draws its power from the juglone-rich green hull harvested before maturity. It tightens lax tissue, clears damp stagnation, and creates an inhospitable environment for parasitic overgrowth throughout the digestive and lymphatic terrain.
