Calcium bentonite is a mineral formed from clay, pressed over geological ages into rock-hard, tan to off-white sedimentary deposits. It is mined and pulverized for its medicinal and absorptive properties, according to scientists at Arizona State University Biodesign Institute. Calcium bentonite is both non-toxic and versatile in its ability to absorb undesirable substances for removal from your body or from food products, and in its ability to absorb beneficial substances and deliver them to your body for health and beauty benefits.
Medical
Medical researchers at the Arizona State University, School of Life Sciences, report that a study of 20 clays from around the world, of types that included calcium bentonite, documents antimicrobial qualities in at least three samples, two of which are mined in the United States. The susceptible bacteria include methicillin resistant staphylococcus aureus, MRSA, a bacteria called Mycobacterium ulcerans, a tuberculosis-related organism that causes a flesh-digesting disease called Buruli. The bentonite clays also showed effectiveness against Escherecia coli and Salmonella, both of which are causes of foodborne illness. However, some clays, including calcium bentonite, are contaminated by ground water pollution and may also contain toxic mineral elements like arsenic. Do not use them for medical purposes unless you consult your doctor and use only materials known to be pure and clean.
Clarifying
Geologists reporting for Manitoba's Mineral Resources in Manitoba, Canada, describe calcium bentonite deposits as clay beds compressed into thick, rock-like, sedimentary strata. The calcium bentonite is mined and pulverized for use by the food industry. Calcium bentonite absorbs organic color and odor molecules from vegetable oils, making it water-clear. Colors and aromas can then be reintroduced to meet consumer expectations. Soap manufacturers often use recycled oils which can be purified with calcium bentonite before adding appealing colors and aromas for bath or laundry products.
Pharmaceuticals and Cosmetics
Industrial geochemists with Minerals Zone.com, describe hydrated forms of calcium bentonite which display the physical properties of a gel or paste when made with water and glycerin. This serves as an inert and non-toxic carrier for hygiene and cosmetic agents in toothpastes and skin creams. A dense mixture of bentonite, blended in a 1 to 4 proportion with water, produces a heavy, grease-like substance, the ointment base for many topically applied medicines, and even as a base for lipstick.
