Yellow dock root is one of Western herbalism's foundational 'blood cleansers' — a term describing its ability to support liver processing of waste products and improve iron bioavailability through its tannin-chelating action. It is particularly valued for iron-deficiency anaemia, chronic skin conditions (eczema, psoriasis), and sluggish liver with constipation. Its iron-rich content combined with liver-supportive bitters makes it synergistic with nettle for building blood.
