Related Powder.—SWEET'S RED POWDER. A preparation termed Sweet's red powder, has been considerably employed by many practitioners. It causes emesis as well as catharsis, and, as an alterative, is reputed of considerable efficacy in many chronic diseases. It is prepared as follows: Take of mandrake root, in fine powder, 5 ounces; bloodroot, in fine powder, 1 ounce. Place the powders in a percolator and thoroughly exhaust with alcohol. Evaporate the tincture obtained to the consistence of molasses, and, while hot, add to it finely-powdered white sugar, 6 ounces; croton oil, to which a little salt of tartar has been added to neutralize the acrid principle, 1 drachm; and oil of cloves, ½ drachm. Mix thoroughly together, spread on glass or on a plate to dry, finely powder, and bottle. The dose is from 5 to 30 grains. Probably this powder might be prepared as follows: To 6 ounces of finely-powdered white sugar, add 1 drachm of croton oil, prepared as above, and ½ drachm of oil of cloves; mix, triturate thoroughly together, and, continuing the trituration, add, gradually, 160 grains of resin of podophyllum and 46 grains of sanguinarine.
