Abstract: The invention is a method of treating cancer comprising administering an effective amount of either a composition of three herbal extracts consisting essentially of 30% to 70% by weight Goldenseal, 20% to 40% by weight of Myrtle, and 5% to 20% by weight of Centaurea, or a composition of seven herbal extracts consisting essentially of 3% to 5% by weight Centaurea, 1.5% to 4% by weight Capsicum, 1.5% to 4% by weight Lobelia, 20% to 40% by weight Myrrh, 30% to 50% by weight Echinacea, 15% to 25% by weight Goldenseal, and 3% to 5% by weight Myrtle. The compositions were prepared by separately extracting each herb by mixing the herb in water, ethyl alcohol, or a mixture of water and ethyl ether, boiling and cooling the mixture, allowing the mixture to stand for about two weeks, filtering the mixture to obtain the liquid phase, and combining each of said extracts to obtain said compositions.
