For your gut flora and the flora in your garden
Today is National Diatomaceous Earth day
DE for short, diatomaceous earth looks like white clay and consists of microscopic skeletons of algae (diatoms) that have fossilized over millions of years. The diatoms are rich in silica.
DE is toxic to mammals but has many industrial uses, including water filtration and dynamite production.
The food grade DE is used as an anti-caking agent in the agricultural and food industries. Food grade DE is safe to use; it passes through the digestive system unchanged and does not enter the bloodstream.
One major health claim for diatomaceous earth is that it can help detox by scrubbing the digestive tract. This claim is based on its ability to remove heavy metals from water, which is the property that makes diatomaceous earth a popular industrial-grade filter. You can take a table spoonful in water on an empty stomach, just as you would with clay. BE careful not to inhale diatomaceous earth, as it will irritate and scar the lungs.
DE is also used as an insecticide. When it comes in contact with an insect, the silica removes the waxy outer coating from the insect’s exoskeleton, and the insect dies of dehydration. Some farmers also believe that adding DE to livestock feed kills internal worms and parasites.
I use DE in my garden when I have an infestation of aphids or spider mites or pests that are brought in by ants, because I refuse to use chemicals in my garden.
