THC removal means the actual separation of THC molecules from a given product. Treehouse Hemp removes THC through a patented process. Other companies use dilution to achieve compliant levels of THC. Dilution is simply adding filler material to lower the THC level of a product to the federal limit of 0.3%. This also dilutes the potencies of all other cannabinoids including the minor cannabinoids likely responsible for the desired entourage effect. We perform both 3rd party and in-house testing to ensure an undetectable amount of THC in every product.
