All Hemp Seed Oil contains CBD .. to a greater or lesser degree.
Hemp Seed (from which the Oil is extracted) itself doesn’t contain any CBD.
The bud of a Cannabis Sativa flower is coated with trichomes, which contain more CBD than any other part of the plant. Seeds may be coated in CBD from the flowers and at pressing, the CBD may be transferred into the Oil.
Therefore the Oil does not have a consistent percentage of CBD present when tested as it depends on the strain of Hemp from which the Oil was produced as well as how rigorously the Seeds were cleaned/washed before pressing for Oil.
