Mucu-Tone was a multi-purpose “alterative tonic” which was manufactured for a brief period in the early 1900’s. Two of its active ingredients are Cascara sagrada and Nux vomica. Nux vomica is the poisonous seed of the Strychnos nux-vomica tree and contains ca. 4% by weight of the poisonous alkaloid strychnine. Cascara sagrada is the bark of the bearberry tree (Rhamnus purshiana). Known as a laxative by native Americans, cascara sagrada was widely used in over-the-counter medicines until banned by the FDA due to its toxicity and potential carcinogenicity.
The Rexall company was started in Boston in 1904 by Louis K. Liggett, who also founded the United Drug Company. The “Rexall” name was derived from the words “Rx to all,” an allusion to the company’s goal of providing low-priced, high-quality prescription medications. The Rexall name was franchised to individual owners, and soon the company lost profits to more competitive retail pharmacy chains. The Rexall company survives today as Rexall Sundown, Inc., which markets vitamins and healthy living products.
