Since testing positive for Covid in October 2020, I’ve had trouble taking a deep breath without coughing. Also, with at the end of taking a deep breath, I felt a slight discomfort like I had pushed my lungs too far. After 3 days of trying Herb Lore’s Mullein Tincture, my breathing felt ‘normal’ again. Even with seasonal allergies kicking in (and pollen levels very high), deep breaths do not trigger any cough or pain. I just ordered some of the non-alcohol Mullein for my 81-year-old mother and am hopeful that she will experience similar lung health improvement. Love this stuff! Highly recommend anyone who wants to improve their lung health to try this! K.J.
