Ovoferrin

Ovoferrin was a tonic originally produced in the United States by A.C. Barnes Company^[1] of Philadelphia, Pennsylvania^[2] and later by Zonite Products Corporation, which acquired A.C. Barnes Company in 1929.^[1] The product grossed approximately $400,000 annually in 1929.^[2] Both Ovoferrin and Argyrol continued to be exclusively manufactured by A.C. Barnes Company, which became a subsidiary of Zonite Products Corporation. On January 2, 1946 Ovoferrin and Argyrol were assigned to Erwin, Wassey & Company, a New York based advertising agency.^[3]

Chemical composition

Ovoferrin's manufacturer described its makeup as being neutral in reaction. A tablespoon was stated to be equivalent to a single grain of elementary iron. When potassium ferrocyanide is added to Ovorferrin no change is observed. However the addition of hydrochloric acid to Ovoferrin produces a well-known color and precipitate of Prussian blue. This indicates that hydrochloric acid changes Ovoferrin, producing an inorganic iron.^[4]
