menstruums |
1 definition found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Menstruum \Men"stru*um\, n.; pl E. {Menstruums}, L. {Menstrua}. [L. menstruus. See {Menstruous}.] Any substance which dissolves a solid body; a solvent. The proper menstruum to dissolve metal. --Bacon. All liquors are called menstruums which are used as dissolvents, or to extract the virtues of ingredients by infusion or decoction. --Quincy. Note: The use is supposed to have originated in some notion of the old chemists about the influence of the moon in the preparation of dissolvents. --Johnson.
