This is a great product. I have used the allergy tablets for several years and they worked great. I decided to use the allergy & sinus because sometimes my sinuses bother me along with my allergies. They work wonderfully. I prefer the liquid drops, however the tablets work just as well. I bite into the tablet, place it under my tongue and let it dissolve. There is no nasty taste, no side-effects, no drowsiness .... no complaints and the price is reasonable.
I always prefer natural alternatives.
