The invention herein describes a procedure for organically extracting the
lipophilic components from plants of the Family Euphorbaciae,
specifically but not limited to the genus Croton. The extraction (CGO
110), is deplete of the normal proanthocyanidin content found in the
parent material, yet retains its pharmacocological abilities and unlike
the parent material, is selectively cytotoxic to cancer cells. The
depletion of the proanthocyanidin components makes the product more
amenable to preparations for the benefit of ameliorating both human and
animal disease.
