This product really helped my sinus issue. It didn't take it away completely but it did what it claims to do. I'll purchase again as needed.*

I had the worst post nasal drip, just started taking this yesterday, one with breakfast, one with dinner, it was the first night I slept. It worked so
well for me, and I have tried other natural things, but this was amazing. So happy I decided to try it.*

Dump the drugs! Go all natural by T. Small on Jan 4, 2018 (Source: Amazon)

I felt great with my sinus problems by marie p. on Jan 4, 2018 (Source: Amazon)

I am on 17 medications and only 57 years old. It's hard for me to know when something is working or not. But wow...I felt great with my sinus problems. When the 1st bottle was finished I could feel pretty quickly when it wore off. So I tried one more bottle...thinking it must have been a fluke...and voila...I felt amazing... sinus pain, pressure, and dryness inflammation gone. I thought nothing would ever help me. I've tried everything out there and even had two sinus surgeries and this little bottle turns out to be my miracle. Great job LES Labs and thank you !*

This product does appear to be working. I have only taken 3 doses so far but have already noticed an improvement with postnasal drip. My sinuses seem clearer. It's a little pricey but worth it if it totally resolves my symptoms ????*

Try it!*

Very pleased! by Ishmael muhammad on Dec 27, 2017 (Source: Amazon)

This is eliminated sinus congestion. Normally in the winter about twice a week I would be congested at night and when I woke up. I haven’t had any congestion since I’ve been taking these.*

This product is working for me without side effects. by Retired in California on Dec 27, 2017 (Source: Amazon)

This product product is working for me and I am having fewer sinus headaches. I hope with continued use it will get even better.*

It works! by April C. Naill on Dec 17, 2017 (Source: Amazon)

This is the only product that I’ve found that works for post nasal drip. I have it so bad I’ve seen three specialist with no resolve. I bought this product based on the other reviews and out of desperation. My post nasal drip is so bad I constantly have to clear my throat and wake up gagging at night. I take one pill in the morning and one at night and my symptoms aren’t as bad. I’d say I’m 90% better.*
