Have used mullein in both tea and pill form. It does help some people but not much for me. My copd is both emphysema as well as chronic bronchitis. The bronchitis causing most of the mucus. I take mucinex dm daily and fisetin which is a natural anti-inflammatory (100mg twice daily with meal). The fisetin helps prevent or lessen mucus and then mucinex and lots of water thins whatever mucus there might be.
"Huff" breathing helps bring it up and I also use a "flutter" device that creates vibrations to loosen mucus. You can learn about Huff breathing and Flutter devices by searching this site.
It ain't easy being wheezy.

I drink it all the time.

So I ordered some. The first cup my lungs felt good, then the next time I drink it made my chest tight so I'm not gonna drink anymore..have a blessed day

I get both of them off eBay. Order on line delivered in mail. [https://www.ebay.com/itm/265316688930?_trkparms...]

Hope the link works, or just look it up. Should be able to get it at any herbal store also. I find it cheeper on line.

Hi Donna, this is Victoria. Mullein did not agree with me.. but I do have sensitivities to some herbs and medications. I didn’t do well with Mucinex either or huffing. Although those helped Gary, I think we’re all different. The only way you’ll know is if you try it.🤗🌻
