If I've been working in a smokey place, I use saline spray to help but I have not been sick with anything for all these years. I think it's building my immune system even when I'm in contact with a lot of people.
I recommend taking the blends of at least 5 to 10 or more. Not just one mushroom. I ran into a number of ordering problems between my store and online and was without for a month, also was around smoke again AND found a major mold issue in my new place. So... I got sick. Not nearly as bad as I used to though. I tried to prevent getting sick with Reishi tea, and bought the only blend I could find shitake/maitake but it just wasn't enough and I got a full blown sinus infection. Difference is back in the day I would be in bed unable to walk my dogs even, now I am fine, just unable to do yoga or go to work and I sleep a lot.
I finally got ahold of a medicinal mushroom blend with about 10 or more strains and I'm getting better. Makes me really appreciate how well they were working all these years. Highly recommend them!!!
