Kellogg's Sanitone Wafers

Kellogg's Sanitone Wafers was a brand name for a dietary supplement, advertised as as a "nerve force" restorative (and, in fact, boasted to being the "greatest nerve strengthener known to science"), that was manufactured and distributed by F. J. Kellogg Co. (Battle Creek, Michigan). According to a Kansas State Board of Health analysis, the wafers were "tablets, coated with sugar and calcium carbonate, weigh[ing] about .983 grams, and found to contain chromium salt and phenolphthalein."
