North America:1700-1900 Used as a pot herb by the English and Swedish settlers. The fresh leaves were boiled in lard or sweet cream for scrofulous ulcers, sore eyes, and glandular swellings. The roots and seeds were given in cases of dysentery. The Native American tribes used yellow dock as both a medicine and a dye. The bruised root was used as a poultice for abrasions and sores, itching of the skin and eruptions. 3.
All Docks are under Jupiter, of which the Red Dock, which is commonly called Bloodwort, cleanseth the blood and strengthens the liver, but the Yellow Dock root is best to be taken when either the blood or liver is affected by choler. All of them have a kind of cooling, drying quality: the Sorrel being most cool and the Bloodworts most drying.
