Once again medical truths of the recent past are being up ended. It appears that mom wasn’t always right about cleanliness- NOT! Cleaning a wound and dressing it is still the best approach but an alternative way of thinking about antibacterial chemicals inspired by medicinal clays appears to be gaining interest. Spurred by the evolution of Methicillin-resistant Staphylococcus aureus (MRSA) or the flesh eating bacteria scientific investigation into medicinal clays is beginning to unlock their secrets. Those secrets appear to be that certain chemical ions like Fe+2, Cu+2 and Zn+2 or in other words Iron,Copper and Zinc which ionize with two positive valences are important to the clay’s antibacterial properties. More work needs to be done but these scientists appear to be onto something.
So the take away message of this research in my mind appears to be that if you can change the environment that a microbe likes you can kill it.
While looking into this I found that montmorillonite clay has been used as part of the scaffold for tissue engineering in bone. I’ve included the link below.
