Lazarus Naturals offers CBD oils and tinctures using industrial hemp. The company uses kosher alcohol to purify and distill the oil to limit the risk of contamination with solvents. A third party tests the CBD oil for heavy metals and pesticides. The results of the tests are available through their website and they offer transparency about the details of the tests. While they admit to trace amounts of THC in some of their products, they note that the amount is less than 0.3 percent and their products do comply with the standards set by the U.S. Federal Government.
