@Chocolove Thank you so much for the link on sinus infections! I've been squirting my nose with saline solution but I can see now that it's woefully inadequate. A vaporizer to deliver essential oils deep into sinus cavities makes a lot of sense. What essential oils do you use? There were several different opinions on this subject. On a side note, you mentioned adrenal support because sinus infections can stress the adrenals. I have a problem with cortisol surges. Will taking adrenal support intensify this?
