Saw Palmetto and Testosterone Level

Is Saw Palmetto good for bringing down your testosterone level? My PSA level is 0.3. Normal is 0.0 to 4.0. I understand too much testosterone can elevate your PSA level. I had my prostate removed several years ago.

Saw Palmetto is not known to decrease testosterone levels.
The goal of holistic therapy in prostate related problems is to decrease the risk of cancer by improving the general state of health with diet, exercise, outlook on life and herbs to strengthen the body systems, as required for each individual's current state of health and medical history.
