Bentonite and zeolite are two materials that are used in alternative medicine. Although both bentonite and zeolite are used to cleanse the body, the two purported healing agents come from different sources. Bentonite is a clay whereas zeolite is a crystallized mineral created by lava and water.
Sodium montmorillonite is a naturally occurring clay and hence its properties and composition can vary. It falls into the smectite group and is largely used for its swelling and adsorption properties.
Bentonite usually forms from weathering of volcanic ash, most often in the presence of water. However, the term bentonite, as well as a similar clay called tonstein, have been used for clay beds of uncertain origin. For industrial purposes, two main classes of bentonite exist: sodium and calcium bentonite.
Bentonite is listed as being used in foundry sand bonding, bleaching clay in oil refining and decolorizers, filtering agents, water impedance, animal feed, pharmaceuticals, paint, plasticity increasers, and ironore pelletizing. Another source reported Bentonite as being used as an adsorbent, emulsion stabilizer, and suspending agent.

Activated calcium bentonite is the most widely used bentonite in winemaking as it has a high swelling index and a pH of between 9 and 10. It also has a high proportion of exchangeable sodium and calcium. It is obtained by activating natural calcium bentonite with sodium carbonate, and then drying and grinding the resulting mixture.

Smectite refers to a family of nonmetallic clays primarily composed of hydrated sodium calcium aluminum silicate. Common names for smectite include montmorillonite or sodium montmorillonite ("sodium bentonite" or "Wyoming bentonite") and swelling bentonite ("Western bentonite"). Chemical Name: Hydrated sodium calcium aluminum silicate
from SigmaAldrich (UK). Natural bentonite clay (Beloon) (BC) was collected during the dry season from Azaz, northwest of Aleppo, Syria (latitude: 36 N, longitude: 37 E). BC purification and activation BC was initially dried in ambient conditions, followed by oven drying at 100 C for 24 h to remove moisture from the clay.
