I gave these exact lozenges to my father in November 2019 when he had what we believe was likely Covid.
I look them myself a couple months later when I think I had it. I never had a lot of coughing. My major symptom was being completely unable to do anything after 7 but go to bed. This last two weeks.
My father was in the hospital for a week. Thankfully this was before they knew what Covid was and were being paid to ventilate people. I believe the lozenges and elderberry I gave him made it less serious.
That is great to hear! I used them one day when my asthma was making it hard to breathe and they helped a lot. They aren’t cheap but are worth the money. I keep the cheaper menthol drops around for mild asthma, but these will be kept for Covid unless I get a bad bronchitis.
