“Made of Phenolphthalein (one and one-half grains in each), Cascara Sagrada, De-emetinized Ipecac and Prunes.”
The following report on the composition of Prunoids is submitted by the Association’s Laboratory:
“From an examination of Prunoids it is concluded that the amount of cascara or extract of cascara in the preparation is very small. Also the quantity of “de-emetinized ipecac” is insignificant. The claim is made:
“The levulose of prunes, a constituent of Prunoids, is hygroscopic and thus when brought into contact with the saliva of the mouth or contents of the stomach, disintegrates and prompt medication is insured.”
“Actually the amount of prunes which may be present in Prunoids is negligible. For all practical purposes, therefore, Prunoids are phenolphthalein.”
According to the information included on and in the box Prunoids are
“An Ideal Laxative, Purgative, and Intestinal Tonic” ... “particularly adapted to the treatment of constipation ...”
They are said to act as an “intestinal tonic”—a claim which in the light of the examination is obviously unwarranted—and because of this, it is said that they:
“Will permanently remove constipation without causing after constipation.”
