Horsford's Acid Phosphate, circa 1885

Prepared according to the directions of Prof. E. N. Horsford, of Cambridge, Massachusetts, this concoction was suggested for dyspepsia, indigestion, headache, mental and physical exhaustion, nervousness, hysteria, night sweats, consumption, and other ailments. According to their advertising: "This Acid Phosphate…imparts new energy to the system, giving the feeling and sense of increased intellectual and physical power."
