Very small - like a drop or two under the tongue. Depending on the sickness - maybe a few times a day. I can’t remember the name of the book and/or author. Unfortunately, I loaned the book out and never got it back. I found this about 15 years ago when I was constantly besieged w/bronchitis. Thought I’d give it a try and haven’t had bronchitis since.
Oh my. I’m on about my 4th week of bronchitis. After 1 zpack of antibiotics and then later at urgent care a breathing treatment (that I had an allergic reaction to), continuous use of mucinex and a vaporizer. I’m getting better but it’s slow.
I’m going to research your oil of oregano a little for dosage. Thanks.
