since the day JFK was killed I had a sore throat and ear pain from a nearly deadly flu in my very early childhood.
Both improved as well as well as my weak immune system. Furthermore, I contribute it to olive leaf extract that five of my 10 fungus infected toe nails spontaneously healed. I am hoping the others will do so as well in the near future.
It helped improving my gut pain. Yes, you read right, my guts were painful and sort of inflamed or whatsoever. I don't care for the proper medical term.
Washing my hair in winter an going out two hours later was a garantee for a cold as well as walking in the rain. This has disappeard.
Now I walk in the snow without a scarf and without a cap. This was impossible all the years ago.
