Editing Pluto Water (section)

== Laxative properties ==
The water's high native content of mineral salts generally made it effective as a laxative within one hour of ingestion, a point emphasized in the company's promotional literature. Company advertisements stated the laxative was effective from a half-hour to two hours after ingestion. The active ingredient of Pluto water was listed as [[sodium sulfate|sodium]] and [[magnesium sulfate]], which are known as natural laxatives.  The water also contains a number of other minerals, most notably [[lithium]] salts. The sale of Pluto water was halted in 1971 when lithium became a [[controlled substance]].<ref name="hoosier" />
