It has also been used as a base ingredient for tissue engineering.<unk>  is used in many dermatological over-the-counter remedies, such as in acne treatments (this information may not be mentioned on the label specifically). Internal use There are many over the counter remedies for internal use that contained<unk>  before discontinuation. Examples include Kaopectate (Upjohn), Rheaban (Leeming Div., Pfizer), and Diar-Aid (Thompson Medical Co.). The labels on all of these showed the active ingredient to be Attapulgite, each tablet containing 600 (or 750 mg) of this component along with inert materials or adjuvants. However, since April 2003, attapulgite medication was discontinued due to lack of evidence according to the U.S. Foods and Drugs Administration.

Experiments demonstrated that weightlessness leads to a rapid bone depletion, so various remedies were sought to counter that. A number of pharmaceutical companies were asked to develop calcium supplements, but apparently none of them were as effective as<unk> . The special<unk>  that was used in this case was Terramin, a reddish<unk>  found in California. Benjamin Ershoff of the California Polytechnic Institute demonstrated that the consumption of<unk>  counters the effects of weightlessness. He reported that "the calcium in<unk>  ...is absorbed more efficiently ...<unk>  contains some factor or factors other than calcium which promotes improved calcium utilization and/or bone formation." He added, "Little or no benefit was noted when calcium alone was added to the diet."
