American Heritage® Dictionary of the English Language, Fourth Edition
- n. Any one of a family of hydrous aluminum silicate minerals, whose molecules enclose cations of sodium, potassium, calcium, strontium, or barium, or a corresponding synthetic compound, used chiefly as molecular filters and ion-exchange agents.
Century Dictionary and Cyclopedia
- n. A generic name of a group of hydrated double silicates in which the principal bases are aluminium and calcium or sodium. They are closely allied to the feldspars among anhydrous silicates. They are decomposed by acids, often with gelatinization; and most of them intumesce before the blowpipe. Among them are analcite, chabazite, harmotome, stilbite, etc. They occur most commonly in cavities and veins in basic igneous rocks, as basalt or diabase, as at Bergen Hill, New Jersey; they thus often fill the cavities in amygdaloid.
- n. mineralogy Any of several minerals, aluminosilicates of sodium, potassium, calcium or magnesium, that have a porous structure; they are used in water softeners and in ion exchange chromatography.
GNU Webster's 1913
- n. (Min.) A term now used to designate any one of a family of minerals, hydrous silicates of alumina, with lime, soda, potash, or rarely baryta. Here are included natrolite, stilbite, analcime, chabazite, thomsonite, heulandite, and others. These species occur of secondary origin in the cavities of amygdaloid, basalt, and lava, also, less frequently, in granite and gneiss. So called because many of these species intumesce before the blowpipe.
- n. any of a family of glassy minerals analogous to feldspar containing hydrated aluminum silicates of calcium or sodium or potassium; formed in cavities in lava flows and in plutonic rocks
- Swedish zeolit, from Greek zein, to boil (from its swelling and boiling under the blowpipe); see yes- in Indo-European roots. (American Heritage® Dictionary of the English Language, Fourth Edition)

“A few months ago, I suggested to Willy that he should try a detoxification substance called zeolite to remove some of the deep toxins that may still reside in his body and brain, as the result of being chemically compromised for so many years as a child (a lack of nutrients leads to weakened detoxification ability, as all detoxification pathways in the body and the brain are 100% nutrient dependent).”
“Litonite is a zeolite, that is, a special gravel that absorbs mineral salts and then gradually releases them to plant roots via an ionic interchange.”

“It's a miracle mineral called zeolite, and it is perhaps one of the most important substances on Earth today.”
“Some people even feel it necessary to take mineral called zeolite to help ride their systems of harmful heavy metals, but consuming zeolites may have unknown ramifications as well.”
