The Test of a Tonic.

The field and function of a systemic tonic is gen- erally understood and appreciated by both physician and patient. To stimulate, whip or goad the vital pro- cesses is not to "tone," but, on the contrary, to ulti- mately depress. A real tonic is not a mere "pick-me- up," but some agent that adds genuine strength, force and vigor to the organism. The genuine tonic is a builder or reconstructor of both blood and tissue. Any agent which will increase the power of the blood to carry and distribute the life-giving oxygen is a tonic in the best and truest sense of the word. Iron in some form is an ideal tonic, as it builds up the vital red cells of the blood and the hemoglobin, which is their essential oxygen-carrying element. Of all forms of iron, none is quite as generally acceptable and readily tolerable and assimilable as Pepto-Mangan (Gude). It creates ap- petite, tones up the absorbents, builds the blood, and thus is a real tonic and reconstructive of high order. It is especially desirable because of its freedom from irritant properties, and because it never causes a con- stipated habit.
