thanks for the suggestion. I was considering Olive Leaf for a while, it does sound great. But it apparently can lower blood pressure and blood Sugar to a point of comatose! There is a big warning for people with low blood pressure and low blood Sugar (my case). So unfortunately, I didn't dare try it, even though it does seem really good.
Yes Pau d'Arco also - very right. I love the taste. Also boil it for long.
