Kruschen salts, still available for sale in some countries, are similar to Andrews Salts and Epsom Salts. Advertisements in 1922 promised health, happiness and beauty for a farthing a day. There were 4 farthings in a penny. The Bank of England’s online inflation calculator calculates that £1 in 1922 would equal £51.25 in 2016. The ad recommended a morning dose, just a pinch big enough to lie on a sixpence, a farthing’s worth, or about 13p in 2015’s money. Not bad if it delivered all it promised:-
“You feel a sense of fitness, of inward cleanliness and refreshment. Your cheeks glow with radiant health – headaches are a thing of the past. You live every moment of your life, rejoicing in the sunshine. Health’s everything.”
Perhaps this explains the penchant older generations had for taking a rounded teaspoonful dose of baking soda in warm water every time they felt a little underpar. The majority trusted what they were told.
The Advertising Standards Authority would surely have had something to say about such “Good Health” claims for a purgative today.
The advertisement appeared on the first page of Good Housekeeping September 1922.
