Yellow Dock Root (Rumex crispus) | Liver, Digestive & Skin Clarity Support

Yellow Dock Root (Rumex crispus)

Yellow Dock Root, botanically known as Rumex crispus, is a cornerstone herb in Western and Ayurvedic herbalism, prized for its rich content of anthraquinone glycosides, iron, tannins, and oxalic acid. Traditionally used as a bitter digestive tonic and gentle laxative, modern research has begun to validate its hepatoprotective, anti-inflammatory, and iron-supporting properties. Available in 50 g and 100 g sizes.

Key Benefits

• Liver & gallbladder tonic — anthraquinone glycosides stimulate bile production and support hepatic detoxification pathways
• Digestive bitters & bowel regularity — mild laxative action via emodin and chrysophanol supports healthy gut motility
• Natural iron source — one of the richest plant sources of non-haem iron, traditionally used to support iron levels and combat fatigue
• Skin clarity support — liver-cleansing action indirectly supports skin health; traditionally used for eczema, psoriasis, and acne-prone skin
• Anti-inflammatory & antioxidant activity — tannins and flavonoids contribute to free radical scavenging and reduced inflammatory signalling

Clinical Research & Evidence

• Hepatoprotective activity: Studies published in the Journal of Ethnopharmacology have demonstrated that Rumex crispus root extracts exhibit significant hepatoprotective effects in animal models, reducing liver enzyme elevations (ALT, AST) and oxidative stress markers induced by hepatotoxic agents.
• Anti-inflammatory properties: Research in Phytotherapy Research identified that anthraquinone fractions from Rumex crispus inhibit COX-2 expression and reduce pro-inflammatory cytokine production (IL-1β, TNF-α), supporting its traditional use in inflammatory skin and digestive conditions.
• Antimicrobial activity: In vitro studies have shown that Rumex crispus extracts exhibit inhibitory activity against Staphylococcus aureus, E. coli, and Candida albicans, attributed to tannin and anthraquinone content (Industrial Crops and Products, 2014).
• Iron content & nutritional support: Yellow dock root is documented in nutritional herbalism literature as one of the highest plant sources of bioavailable iron, with traditional use validated in ethnobotanical reviews for supporting iron-deficiency anaemia alongside vitamin C-rich foods (Economic Botany, 1986).
• Antioxidant capacity: Phenolic-rich fractions of Rumex crispus demonstrated significant DPPH and FRAP antioxidant activity in studies published in Food Chemistry, attributed to quercetin, kaempferol, and hydroxycinnamic acid derivatives.
