I am a big fan of olive leaf as well. Olive leaf is antiviral, antifungal, antiparasitic, and antibacterial. I have had excellent results. Both are high in the active ingredient oleorupin. Look for 18% oleorupin or higher on the label.

I have tried many over the years and for some reason GNC's the one that works best for me. I don't like their price and I have seen it go up 2 times in the last 10 years but it always works for me.

There are a ton of olive trees around Los Angeles. When I cant afford to buy it, I just boil the leaves and drink the tea. I cant say I recommend anyone else do that. One must know exactly what they are doing when picking wild herbs. Though, around the spring, olives should be clearly visible on the fruit baring trees.

Could we please have an Olive Leaf Extract page? My family has used it for our pets and children to quickly recover from conjunctivitis and shingles, and after one megadose yesterday with one cayenne capsule (as a carrier) my husband finally has gotten some relief for the horrible burning associated with chronic prostatitis. Hopefully he will continue to improve, because doctors don't know how to treat prostatitis. I've personally experienced energy and the same sense of well being from olive leaf extract, that I get when I take diatomaceous earth. I just feel that olive leaf extract is deserving of its own page, and hope you will too!
