Madder Root Fine Ground Dry Powder - Rubia Tinctorium 100 Grams

Madder Root Fine ground dry powder - Rubia tinctorium - 100 grams contains rubian, rubiadin, ruberythric acid, purpurin, tannin, sugar & especially alizarin. Although not as a general rule employed medicinally, It is generally used as a dye. The most interesting of the colouring substances it contains is the alizarin, & this is now termed dihydroscyanthraquinone. This occurs as orange-red crystals, almost insoluble in water, but readily soluble in alcohol, ether, the fixed oils & alkaline solutions. The alcoholic & aqueous solutions are rose-coloured, the ethereal, golden-yellow; the alkaline, violet & blue when concentrated, but violet red when sufficiently diluted. A beautiful rose-colour is produced by precipitating a mixture of the solutions of alizarin & alum. When taken into the stomach it imparts a red colour to the milk & urine, & to the bones of animals without affecting any other tissue. The effect is observed most quickly in the bones of young animals & in those nearest to the heart.
