Healing Clay

Better Nutrition - - TRENDWATCH -

The use of mud or clay as a top­i­cal skin treat­ment is a com­mon prac­tice in some cul­tures, and the con­cept of us­ing mud as medicine goes back to ear­li­est times. Now re­searchers from the Mayo Clinic and Ari­zona State Univer­sity have found that at least one type of clay— a blue clay found in Ore­gon— may help fight dis­ease- caus­ing bac­te­ria in wounds, in­clud­ing some treat­ment- re­sis­tant bac­te­ria. The find­ings ap­pear in the In­ter­na­tional Jour­nal of An­timi­cro­bial Agents.

In lab tests, re­searchers found the clay is ef­fec­tive against Escherichia coli and Sta­phy­lo­coc­cus au­reus, in­clud­ing re­sis­tant strains. The lab tests are a first step in sim­u­lat­ing the com­plex en­vi­ron­ment found in ac­tual wounds. The re­searchers cau­tion that not all types of clay are ben­e­fi­cial— some may help bac­te­ria grow. More re­search is needed to iden­tify the an­tibac­te­rial prop­er­ties of different clays.
