One product that I started taking quite a few years ago was Saw Palmetto. This is an herb that reduces prostate inflammation. The best brand I have found is Herb Pharm's alcohol liquid extract. Simply put three full droppers of Saw Palmetto every day in juice or EmergenC effervescent Vitamin C, and you will soon be feeling better unless it is a problem where you need to see a doctor. It will taste somewhat bitter, but you will get used to the taste when you experience the benefits. You can get this product from Vitacost.com on the internet.
A second great discovery in past years involved drinking tomato juice. It not only helps the prostate, but studies have shown that tomato juice prevents cancer also. You can buy 6 oz and 12 oz cans of juice at just about any grocery store. I try to drink at least one 6 oz can of tomato juice each day. In addition to helping my prostate, I also get valuable potassium from the tomato juice which is a body energizer. Then, finally, the juice reportedly helps to rebuild your liver if it is damaged.
