A PSA test, or prostate-specific antigen test, measures the amount of PSA in the blood. While all men have some PSA in their blood, high levels may indicate prostate cancer or non-cancerous problem with the prostate, like prostatitis. According to the National Cancer Institute, there is no established normal or abnormal level of PSA, but age-specific PSA ranges may be used. If you have a high PSA level, talk to your doctor about what this could mean for you, and ways to help reduce the level, including herbal supplements. Before consuming any herb, consult with your doctor to make sure it is safe for you to use.
Take a supplement called PC-Spes2. According to a 2008 study by M Shabbir et al., published in the journal "Oncology Reports," this supplement reduced PSA levels in seven out of 10 patients in the course of one month. PC-Spes2 contains eight herbs and has been shown to inhibit prostate cancer cell growth. Ask your doctor if this is safe for you to consume.
Take a pomegranate supplement. According to Memorial Sloan-Kettering Cancer Center, compounds like tannins and polyphenols in this supplement help reduce inflammation, contain antioxidant properties and help lower serum PSA levels. You can also drink pomegranate juice.
Consume a milk thistle supplement. A 2005 study published in "Cancer Research" by P. Davis-Searles, et al., found that compounds in milk thistle helped suppress prostate antigen secretion, as well as inhibited prostate cancer cell growth. Ask your doctor if you should use milk thistle before consuming it, as it may not be appropriate for everyone.
Drink green tea, or take a green tea supplement. A plant compound called EGCG helps lower PSA levels and decreases the risk of developing prostate cancer, according to a 2004 article by E. Pezzato et al, published in the "International Journal of Cancer."
