The Pharmacopeia of the United States was created to establish standards for drug quality.

The Pharmacopeia (and the National Formulary) were adopted as official standards in the Food and Drug Act of 1906.

Concerns arose that commercial preparations could deviate from those in the Pharmacopeia causing variations in effects.

Licenses required for medicinal alcohol caused pharmacies to add liquor sales.

The Civil War stressed the finances of the journal as Southerners stopped subscribing.

Trimming costs by reducing the number of pages and financial assistance from the college helped it survive.

Procter was honored with a life-sized statue at the headquarters of the American Pharmaceutical Association in 1941.
