This herbal product(eight different medicinal plants) has been developed by a scientist named Sophie Chen. The individual herbs have shown cancer fighting properties. But it is the synergistic results that are valued. Many prostate patients report success in reducing PSA values. Take a look at the attached website for more specifics. Ann heard Dr. Chen speak at a conference in 1998. She is well regarded and her product is being evaluated and used by many main stream physicians. A study in Int J Oncol (GREECE) Apr 1999, 14(4)p713--9,:9908 This particular study investigated the anti-proliferation (growth) and anti-tumor effects of PC-Spes. It was administered as a food supplement to rats. No toxicity was shown. The product was given at two different levels 0.5% and 0.25% but both were active in suppressing both tumor incidence and rate of growth. Ann's NOTE: Time for studies in humans! I have certainly heard a lot of 'anectodal' evidence of its value in reducing PSA (the test for measuring activity in prostate cancer) Take a look at the Wall Street Journal article p B1, Wednesday, May 17, 2000-all about PC-Spes (creation,sales, and use by some physicians and many patients).
