Herbal Therapy for Treatment of Recurrent Prostate Cancer
This study is about Prostate Health Cocktail, a combination supplement that contains vitamin D3, vitamin E, selenium, green tea extract, saw palmetto, lycopene, and soy derivatives. This product is currently available on the market, as herb and vitamin supplements are not regulated by the FDA. Each ingredient has been studied in prostate cancer cells and/or in patients with prostate cancer. At the doses included in this supplement, no serious side effects have been reported.
The purpose of this study is to find out whether Prostate Health Cocktail can lower your PSA. Additionally, we will be looking to see whether taking this treatment causes any unexpected side effects, and whether certain blood tests can inform us about your disease status in addition to your PSA
