Works
Absolutely the best natural Lung and Bronchial pill I have ever used. Also helps with ear issues!

Great buy for seasonal allergies and prone to nasty sinus & double ear infections or sinusitis!
Works great. I had sinus surgery over two years ago now and so my sinuses are still trying to get back to normal. I have horrible allergies and get sinus infections & double ear infections constantly - they get so bad that I will not show any symptoms until it gets so bad that I am really close to a respiratory infection. I know have to keep sinus meds and all the goods on hand the minute I catch on that I am getting sick. These work really well so far for me. Granted it won't get rid of my sinus infections when they're past the normal procedures and have to go to the doctor, but they do help with some of the pain and if I catch it early then it will get rid of it. I keep a bottle of these in my medicine cabinet. It's a good deal for the price as you get a lot in the bottle and I liked the ingredients! Will continue to purchase and have on hand when I need it! Thanks!

Natural Lung, Bronchial & Sinus Health
I love this product and will continue to use when I need it! It really works! I have mold in my office and was coming home wheezing. When I took the product it cleared that up along with my sinuses. It was packaged well, it came quickly and it is a good price for a product that is effective.

Worth the money
Have used this for over 25 yrs and has helped my bronchial and sinus issues. Is not an overnight solution but over time it can make a huge difference. Even my doctor has commented. Zero side effects or taste

Been taking for 6 days now and I noticed that I don't sneezed a lot in a day, I still do but not as much as before,a bit expensive though coz I have to take 3x a day and the content only 45. I don't take antihistamine since I take this. I breathe easier too. Will buy again 01/08/25: Bought again, wishing its cheaper huhuhu🥲 it works but doesn't last long, only for about half a day at most

This is the first year I’ve ever experienced Having so many chronic sinus inflammation problems. I thought I was getting constant sinus infections but it’s just inflammation. I had done rounds of antibiotics, which always seem to clear it up, but within about two months I’d get another one. I finally realized that it wasn’t sinus infections. I Only had inflammation. I never felt sick, Only stuffy and sounded sick when I would talk. Our local supplement store recommended these and honestly they have been a godsend. I haven’t had another sinus flareup since I’ve been taking them. They’re worth a try if you’ve been struggling a lot. I take one in the morning and one at night and feel so much better.

Quand j'ai commencé, j'avais gros rhume, bronchite, sinusite, bref... J'ai vu une très nette amélioration en quelque jours, jusque être au top en maximum 1 semaine. J'ai continué et tut est parfait Vais continuer à prendre cette référence (Attention au délai de livraison un peu long si urgent ?)
