If you grew up in the south it is likely you have heard the old adage “God made dirt, and dirt don’t hurt,” but is there something really to that?  You many have seen a tv show about individuals with a drive to eat non-food items also known as pica, but when it comes to eating dirt, this phenomenon is often referred to by a more specific term “geophagia.”  When someone is exhibiting geophagia they are most likely struggling with a deficiency.  In some parts of Africa eating the soil is considered a telltale sign of a pregnancy.  One of the most interesting examples of geophagia is the kaolin ingestion common in the Georgia Piedmont region that appears to me mostly generationaly driven.  If you visit many small stores in this region you will come across “novelty” dirt, but the locals all know the dirt isn’t likely to be just a novelty.  If you grew up in this area you may have developed an affinity for the taste of this dirt and crave it like others crave various treats from their childhood.  With all this draw to eat dirt, is there any health benefit to eating dirt?  Let’s dig a little deeper.

In recent years microbiologists and immunologists have been working hard to discover what is causing the great shifts in allergies and inflammatory diseases which have been witnessing an upturn since as early as the 1980’s. A new study from Russia and Finland has found that children who were growing up in the country as opposed to more urban areas experienced fewer allergies and had more Acinetobacter naturally occurring on their skin.  Acinetobacter is one of the good bacteria that you were warned about killing if you kept using so much hand sanitizer.  To test their theories scientists brought out the mice. They took one group of mice kept in clean litter in a laboratory setting and a second set of mice in soil saturated litter and stored in a barn. After 6 weeks the mice in the “dirty” cage were less susceptible to allergens and asthma and had a greater presence of “good bacteria” in their guts. The mice in the “dirty” cage also had higher levels of anti-inflammatory proteins that are known to ward off asthma.  

Perhaps a more familiar form of soil used for health purposes is clay.  Bentonite clay is used internally to bind toxins as part of some detoxification routines.  One of our most popular chinese herbal supplements ~ Classical Pearl, created by my teacher in Portland, Oregon, has a small amount of mineral rich clay that is used synergistically to detoxify while balancing organ systems.  During the recent months we have made several changes to our practice.  One of these is moving all of our product sales to e-pharmacy providers or special orders when the product is not available.  Our patients receive a three month prescription that can be directly ordered and delivered to their home.  This is made possible by Crane Herb Company, whose mission follows:  We are dedicated to empowering Chinese herb practitioners in their lives as healers. To this end, we offer you and your patients the finest herb products, prescriptions, books, and medical supplies that we can find. And boy are we grateful for them during these changing times.

In short, a little dirt probably won’t hurt.  You definitely should keep washing your hands, especially when you have been out in public, but some bacteria is ok.  The bacteria on your garden fresh vegetables might even help you be healthier.
