Cured my allergy problem by T├┐ on May 29, 2020 (Verified Purchase)

I had years of allergies. After using Leslabs Sinus & Seasonal for about 2 months my sinus & allergy/runny nose problem just disappeared. It works great!! I highly recommend this product.*

Great for seasonal pollen allergies by Scott M. on May 26, 2020 (Verified Purchase)

Worked wonders within the first few days of using it. Started with 2-3 tablets per day initially and worked down to 1 per day after that. Was taking any and all OTC allergy medication with no relief. Stopped taking OTC allergy medications once I started with this to see how it did and it really worked great. Two downsides,1) while taking 2-3 tablets per day, I did notice heavy chest palpations. I am guessing it is from the butterbur as some other reviewers have mentioned. Once down to 1 tablet a day, no more palpations. 2) the delay in getting refill bottle. Was going to take over a month to get refill. One suggestion, I did not see a subscribe and save option. Would enroll in that immediately.*

This product works for me by EMMANUEL PENA on May 24, 2020 (Verified Purchase)

Seems to really help by Carolyn on May 24, 2020 (Verified Purchase)

My son who is 19 years old has suffered from allergy type symptoms on and off over most of his life. Now that he is in college things seem to have improved. We're not sure if it's because he's in a new environment. Anyway, when he comes home and suffers from symptoms of post nasal and runny nose he takes this and says it seems to help.*

Would recommend! by yrdsale_queen on May 22, 2020 (Verified Purchase)

Amazed at how well this works. I ran it by my herbalist and she gave it her seal of approval. And when it worked so effectively for me, it got my seal of approval too!*

Works great for Seasonal Allergies by J McAdams on May 22, 2020 (Verified Purchase)

My son gets itchy eyes, runny nose & the like every spring. This supplement helped take the edge off his allergies so that he was not miserable at all, just a slight sniffle. Will purchase again next season for sure!*
