Seidlitz powders

The powders were often packaged in a small envelope containing two coloured paper wraps, one white and one blue. The white packets contained tartaric acid, and the blue packets contained a mixture of 75% w/w Rochelle salt (potassium sodium tartrate) and 25% baking soda (sodium bicarbonate). The powdery contents of both packets were stirred or dissolved separately in water and then mixed, giving off carbon dioxide with a characteristic fizzing sound.[https://news.google.com/newspapers?nid=1144&dat=19210713&id=rFcbAAAAIBAJ&sjid=7EkEAAAAIBAJ&pg=5966,4003384 Why do Seidlitz Powders fizz?], The Pittsburgh Press (PA), 13 July 1921 The drink was described as "a cooling, agreeable draught".{{cite book

After ingestion, the powder combines with gastric juices to develop cathartic intestinal gases which can be somewhat helpful in evacuating the users' bowels. However, their use can also lead to unpleasant side effects,[https://jamanetwork.com/journals/jama/article-abstract/230926 WHAT A SEIDLITZ POWDER DID; HOW AN ACUTE OBSTRUCTION WAS RELIEVED BY POSTURAL CHANGE] and can even be fatal[http://www.webpanda.com/ponder/epitaphs.htm Epitaph of a woman who apparently died from Seidlitz powder] in subjects with conditions such as hernia, bowel obstruction or other ailments.

Seidlitz powders, manufactured by numerous chemical factories from the early 19th century onwards, take their name from the village of Sedlec near Most, Czech Republic (previously in Bohemia). The village seems to have received its Germanic name (Seidlitz) some time after 1526, when the Battle of Mohács brought about the collapse of Medieval Hungary. The Lands of the Bohemian Crown fell under the control of the Habsburgs, the German-speaking rulers of Austria (later the Austro-Hungarian Empire).

Although Seidlitz powders have a digestive effect, they should not be confused with 'Sedlitz water' (also named for Sedlec), a well-known bitter mineral water which has been used since the 16th century as a digestion regulator and laxative. Sedlec (Seidlitz) was described in an 1867 guide to European spa towns as "a wretched-looking place, hardly meriting the name of a village, and the wells - whence the water should be derived - are a few shallow, circular pits, whose contents very seldom find their way to this country [ie England]." The Sedlitz water has a chemical analysis similar to sources in nearby towns such as Zaječická hořká from Zajecice (NB German name 'Seidschitz' bitter water'), Korozluky (Ger: Kollosoruk) and Bílina (Bylany or Püllna). The water itself was characterized as "a yellowish, somewhat oily-looking fluid, with a nauseous, intensely bitter taste."{{sfn|Madden|1867|p=241-2}}

These and similar products - with somewhat interchangeable terminology - appear to have no connection with Seidlitz powders. Likewise, the powders have little connection (apart from the digestive effect) with these types of mineral-rich water which were evaporated and the residue formed into pills such as Bilina digestive pastilles, not unlike Vichy pastilles.

Though rarely used today, the term "Seidlitz powder" lives on as a lyric from the popular song "A Fine Romance" by Jerome Kern and Dorothy Fields. Written for the 1936 musical film, Swing Time, with Fred Astaire and Ginger Rogers, it was released on a 1956 jazz album by Ella Fitzgerald and Louis Armstrong, Ella and Louis Again, with the lines "We two should be like clams in a dish of chowder / But we just fizz like parts of a Seidlitz powder."

"Sounds like a seidlitz powder" is in a O. Henry story, "The Foreign Policy of Company 99".

One of the four clerks of Dodson and Fogg is mixing a "Seidlitz Powder," perhaps to treat a hangover, in chapter 20 of Charles Dickens' Pickwick Papers.

Noël Coward would tease the US theatre critic Alexander Woollcott “by recalling that one of [the latter’s] critical colleagues had called him ‘the Seidlitz Powder of Times Square’.” [Barry Day (2021), Noël Coward On & In Theatre, Alfred Knopf: New York, p.279]
