You probably do this already, but if not, look into drinking mullein tea. It is close to miraculous for respiratory issues.
We get our fresh mullein leaves, stems, flowers, from that top notch #1 best quality company, Mountain Rose Herbs. Someone suggested them to us. Their stuff is the freshest and therefore the most potent.
After steeping the tea, just make sure to strain it well, to remove the tiny hairs of the mullein leaves from being ingested, as some might find them irritating to the lungs. We didn’t, but I still strain it anyhow.
I also get Wormwood, Black Walnut tincture, and Black Seed oil from them as well.

As a long time smoker I can attest to this, but not as miraculous as high niacin doses with NAC.
Thank you for posting your source for black seed oil. Mountain Rose is good stuff. I buy dried hibiscus (roselle) from them, great color and taste as tea or flavoring for kombucha.
I’ll look for some at your link. I’m taking the Black Seed Oil and I bet it would go down better mixed in some of that. I put my dose today in a cup of hot green/peppermint tea. It was just OK. The day I took it in equal part honey was a shocker. It shocked my lungs right back into working after more than a year.
Thanks Kalamata!
