NOTE:

 

Penn State University announced in 1995 that minced horseradish holds promise in decontaminating wastewater and now says it may clean contaminated soils as well!

Penn State's center for Bioremediation and Detoxification reports that minced horseradish combined with hydrogen peroxide can completely remove chlorinated phenols and other contaminants found in industrial wastes. Experiments involve applying the mixture directly to tainted soils or growing horseradish in contaminated soil and rototilling the roots just before applying hydrogen peroxide!

The cleansing properties of horseradish have been known for more than a decade, however creating a purified form has been far too expensive. This method has proved to be just as effective, but at a fraction of the cost!
