I have notice something of this so please explain: Olive leave extract is high in tannins and antioxide so this has to be takened alone and not with other herbs for instant with buchu, sage, garlic, golden rod, cleavers and other in other formula with Black-Walnut . And this is recommended for killing yeast and other infection. what is it. I have tried olive leave and cocconut oil and thought of such interaction and neutralization and reduced killing power. hv, can you explain? thanks
