Hello,
I just wanted to add that while on business in Shanghai I became ill with diarrhoea. I went to the Hilton hotel doctor and they gave me montmorillonite powder to mix with 50ml of warm water (3 packets daily), along with salts to drink and levofloxacin antibacterial. I did as instructed and the diarrhoea was cured almost instantly (less than one hour). The montmorillonite powder was branded as "smecta" and manufactured in China by Beaufour Ipsen Pharmaceutical Co., LTD. —Preceding unsigned comment added by 24.166.248.137 ( talk) 14:24, 20 September 2007 (UTC)

Some PubMed links to be potentially included in the article. The topics covered are multiple, including detoxification, adsorption of specific toxins / chemicals, adsorption of virus and others. The uses of montmorillonite are wide and many according to literature, though still require further investigation. A few of the many available articles below:

These are all animal studies, and should be labeled as such in the article. Obviously large scale toxic testing will not be done on humans for ethical reasons, so anti-toxic effects will generally be animal studies. -- Antoniolus ( talk) 22:19, 14 November 2008 (UTC)
Montmorillonite has recently caught my attention as an ingredient in body wraps. Just how much is it used is my question because as the Wikipedia article says it has absorbent properties. Just what is meant to absorb? Sweat? Fat? —Preceding unsigned comment added by 61.9.109.194 ( talk) 02:12, 8 August 2009 (UTC)
This talk page had no table of contents. I just fixed this problem (by adding some space at the top).

Vsmith has stated that "bentonite IS montmorillonite plus ~10% volcanic crud n stuff". I would like to see some citation for that.
AFAIK this "truth" is not universally accepted by specialists. Does Vsmith really think that montmorillonite doesn't contain any "volcanic crud n stuff"?
Neither bentonite nor montmorillonite, in their raw state, can be considered in any sense as "pure". This is just simple logic. Both of these minerals vary widely in their contents. Dyuku ( talk) 03:31, 25 August 2009 (UTC)
I have now added this new section, including 41 valid refs. Most of them are quite recent. The progress in science goes on, and let's hope that those with obscurantist views will somehow manage to reconcile themselves to new ideas and research.
Of course the section can be improved and expanded, but this takes time. Dyuku ( talk) 03:38, 25 August 2009 (UTC)

When I search google ( http://www.google.com/search?q=Montmorillonite+clay), many of the results are related to it's use in humans, yet when I come to Wikipedia to learn more about it, they talk about all it's uses except this. Article history shows someone removing large amounts of sourced info due to it being "primary". That's a counterintuitve rule for an info site, but ok. (I rather read primary sources directly than what some one thinks about it (secondary sources) and then form my own conclusions. You must start with information, right or wrong, first otherwise the third-party's analysis of it isn't very useful.)

In the uses section it is stated "Hence, Sodium Montmorillonite has come to be used as the major constituent in non-explosive agents for splitting rock in natural stone quarries...".

I've reverted the luminescent minerals category.
This was unsourced. It seems unlikely that a compound like this would be luminescent, and most unlikely that it would be a " luminescent mineral", implying eye-visible luminescence for the mineral mass as found.
Of course there is some thermoluminescence. Pretty much any clay will do that, it's used by archaeologists for dating potsherds. It's not interesting as a mineral as here. There is some work on using montmorillonite as a host matrix for exotic luminescent nanomaterials. That's the nanomaterial doing the work, not the montmorillonite, and not in the context of it being a native mineral as here.
