Prune juice is a fruit juice derived from prunes (dried plums) that have been rehydrated. It is a mass-produced product that is often produced using a hot extraction method, and juice concentrate is typically produced using a low-temperature extraction method. It is used by some as a dietary supplement to act as a laxative and to alleviate constipation. It is also sometimes used as a flavor enhancer in tobacco products. It is an ingredient in many cocktails, such as the Purple Dragon, Constipolitan, Go with the Flow, Bowel Banger, Old Yeller, Pile Driver, and Smooth Move.

Prune juice is often produced using hot extraction methods, whereby the prunes are cooked in hot water, becoming a liquid extract, which is then processed into juice. The process of heating and extraction may occur several times with the same batch of prunes, with the collective extracts from each processing then mixed together to create the final product. Prune juice is a mass-produced product.
Prune juice is also produced as a concentrate, whereby low temperature water is used to create a liquid extract. The concentrate has a high sugar content, and is used by food processors to enhance the flavor of and sweeten products, as a humectant to retain moisture in cookies and cakes, and as an ingredient in cereal bars to bind the ingredients.
As a dietary supplement
Prunes may provide a natural laxative effect, and prune juice may serve as a natural laxative for cases of mild constipation. In 1990, the U.S. Food and Drug Administration stated that "the common prune was not an effective laxative".
The commercial distribution of prune juice in the United States first occurred in 1934, which "began with an output of only 40,000 cases".
In central Pennsylvania during the early days of prohibition in the United States, some bootleggers sold a dangerous concoction facetiously referred to as whiskey, which was also called "toilet water", that consisted of colognes, perfumes and prune juice mixed together.
In popular culture
In the Star Trek episode "Yesterday's Enterprise", the Klingon character Worf is introduced to prune juice by Guinan. He declares that it is a "warrior's drink" and begins to drink it regularly in subsequent episodes, even carrying the habit over to Star Trek: Deep Space Nine.
