Chronic Sinusitis....Nevermore?!
Julie B.•January 26, 2018
This is bizarre. I'm a chronic sinusitis sufferer. I order a bottle in desperation. I'm in misery. Sinus draining and painful and feeling just horrid. I take these capsules for a day.
And then...
I'm better. I've never had a sinus infection go away so quickly and without antibiotics. I'm slightly in shock. Happy shock. I can't believe this stuff worked and worked so quickly. I'm now going to make it part of my daily routine. I'm not being compensated for this review, either.

Feel and Hear The Difference!!
Lynn•January 17, 2018
It does not matter what time of the year it is in Florida...I have dealt with post nasal drip for so long (Years).
Sadly, I began to just feel as though I would have to deal with it everyday for the rest of my life. Every year my doctor would tell me to use saline spray. Personally I don't like using saline spray. I believe in getting to the root cause of an issue and resolving it, when possible, as oppose to putting a "band-aide" on it. I decided to order this product after reading the reviews.
I am so pleased with it. I felt a huge difference within 3-4 days of using it. I started off by taking 3 pills a day (6am-2pm-8pm). Long story short... after using the product (3 x a day) for one week, I no longer wake up with the feeling of a layer of "goop" covering my vocal chords.
For those who have post nasal drip and would prefer to pop a pill as oppose to taking time out to use a Nettie Pot or carry around saline spray this is a great product. Use it accordingly and you will feel and hear the difference!!

I felt great with my sinus problems
marie p.•January 2, 2018
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 !
Works- But only briefly for me
Loren Capsopoulos•November 10, 2017
Sorry for the 2 stars, but although this product has wonderful reviews, I can't use it. I took one capsule and had allergic reaction (headache, itching, gastric issues, and insomnia). I will say that it DID work as described, I just can't take it. I finally figured out that I must be allergic to the Butterbur because it is in the Ragweed family of plants. Didn't know that when I ordered it. I don't mean to discourage anyone else from trying this, but be aware of that plant relationship. Update : Decided, out of desperation, to try this again. This time, I took it with a meal and had no adverse reactions. It could have just been fluke the last time. At any rate, I just felt it fair to change my review.
It really works!

I was tired of my sinuses always being stuffy. OTC meds helped some, but not fully. Not a fan of Nettie pots.
I Googled supplements for allergies and came upon a blurb on WebMD that mentioned half a dozen that were known to help alleviate allergy/sinus issues. Armed with this new information, a quick search of Amazon led to this product which contained four of the ones mentioned on WebMD. The reviews were mostly positive and I figured that for $20,I'd give it a try.
Holy wow! I felt relief in FOUR hours! I now go through an entire day without issues. I will definitely purchase again,.
