Bioshield Herbal Oil is a food grade non-toxic oil, however, it will not handle applications below grade, i.e. against damp soil. A better product for the inside of the garden bed would be our AFM Dynoseal. This is a non-toxic waterproofing membrane designed for below grade applications such as foundation walls, roofing, shower pans and fence posts. This will block moisture from rotting the wood and stop the tannins in the wood from leaching into your soil.For the outside of the raised bed, use our Vermont Natural Coatings Polywhey Exterior Stain which is a long lasting, non-toxic, ultra-low odor stain and sealer all in one.
