Abstract
The present invention provides cannabis oil compositions, including cannabis oil compositions containing vitamin E, and methods for preparing the cannabis oil compositions. In some embodiments, the invention provides a method for preparing a cannabis oil composition comprising eluting cannabinoids from cannabis plant material with a solvent to produce an eluate; filtering the eluate with a filter to produce a filtrate; evaporating the solvent from the filtrate with a distiller to produce a distillate; and purging the distillate under conditions sufficient to remove residual solvent. In some embodiments, the method further includes mixing a quantity of vitamin E with the extract. Blended cannabis oil compositions containing mixtures of cannabis oil preparations are also described.
