History & Folklore
Throughout history, madder has been used principally as a red dye for a variety of fabrics. In the ancient world, madder root was taken medicinally to treat jaundice, sciatica, and paralysis, and it was also used as a diuretic. When ingested, madder imparts its distinctive color to bones, milk, and urine, and it probably owed much of its reputation as a diuretic to this property.
Medicinal Actions & Uses
Madder fell largely out of use in the 19th century, and is now only rarely employed to treat kidney and bladder stones.
