A Trojan Horse Made of Clay

Clay 3 _ Medicinal Clay Trojan HorseIt may sound unappetizing, but for centuries, people have ingested clay for medicinal purposes and clay is now being used for cutting edge work in fighting diseases like cancer.

They can insert medications or compounds into the clays and then deliver it in the sense that it helps to time release the medicines. And also can act somewhat like a Trojan Horse, where cells may take the clay material in, not realizing what it is, and then once it’s inside, then all of a sudden the cell goes “uh-oh, there’s something else here besides clay”.In particular cancer treatment is probably one of the most studied fields right now. It’s the idea of delivering cancer drugs. How do you get the cancer drug inside the cancer cell? Cancer cells are pretty clever about what they let in and what they don’t let into their cells.
