So I thought that I would grapefruit seed extract (it was full strength) I was sneezing and looking like I was going to die. The night before last I did not sleep cause every five seconds I was blowing nose and sneezing. I put some in my ears and my left one is still a little clogged. Last night I decided to go a different route and put some fully ozonated olive oil in both my ears and nose this morning I blew my nose and another worm came out!!! I think that I am gonna try the olive oil it does not make me sneeze or cause inflammation. By the way you are not supposed to use the grapefruit seed at full strength so I would use it with coconut oil or ozonated olive oil.
