Yellow Dock
Rumex crispus
Family: Polygonaceae | Parts Used: Root
Yellow Dock is a deeply cleansing root that supports skin health, liver function, and blood vitality. Its bittersweet, cooling profile and anthraquinone content make it a gentle but effective alterative, helping the body clear toxins through the liver and bowel. Traditionally used for chronic skin conditions like psoriasis and eczema, anemia, and sluggish digestion. Its oxalate content means it requires caution with kidney conditions, and anthraquinone laxative action limits it to short-term use.
Traditional Uses
- Chronic skin conditions: psoriasis, herpes, eczema, acne
- Liver and gallbladder disorder support
- Anemia; supports iron absorption and blood vitality
- Addressing sluggish digestion
- Bile stimulation and detoxification
