I am very interested in natural therapeutics and remedies, actually anything natural that might benefit my health & wellness AND do no harm. I had never heard of mullein tea, so I looked it up on healthline.com - a website I often find helpful and balanced. Here is their link for mullein tea:

I will give it a try myself to see if it’s helpful for my moderate COPD-asthma overlap syndrome. Thanks for the tip, and best of luck!
