I never get the flu ever. If I get the sniffles I take 21 caps of olive leaf and within 4 hours I am not sick. Really.
I get fresh olive leaves and dry them and then grind them and I put them in vegetarian caps. For people not wanting the caps they can take it with water but it taste terrible.
One woman with cancer use to fill her blender half way up with olive leaf and add water slowly to the top of the blender and drank that everyday for 3 months and no longer had cancer.
I recently had a patient cure himself with olive leaf from emphysema.
