Patrick, Gusgold, et al. Looking back at some unfinished research--that never went further. There were a protocol of tests completed in mice. A number of Herbal supplements, and some in combination, were designated, by code number/letter systems--which I cannot get into, to ascertain what combinations were used, and by what %.
The Various herbs alone or in combination came from this list: licorice, black cohosh, dong quai, false unicorn, vitex berry root extract, fennel seed extract, red clover blossoms extract, genistein, and gamma oryzanol--and were evaluated for antitumor activity in severely immunodeficient mice bearing CWR22R and PC3 xenografts. The designated herbs in combo, in 5 tests, but known only to the researchers, inhibited tumor growth by 53%, 75%, 80%, 81%, and 87%. Tumor growth suppression was observed with all supplements, relative to untreated controls.
There is some other chatter, typical, to research papers--but the combinations of Herbs that produced the above % reductions cannot be found by me.
Their Written Conclusion was: Our results demonstrated that herbal supplements containing the aforementioned extracts inhibit, the growth of Tumor Xenografts, So in plain language I will translate--these Herbs inhibit or stop angiogenesis mechanisms. They then conclude further: that these supplements warrant further investigation, then the trail grows cold. As replication and continuance of these tests seem to have not occurred.
