This stuff is my saving grace for allergies. I have AWFUL allergies and would usually take Allegra, Claritin or zyrtec. None of them really helped much, but took the edge off. I tried the "D" version of those medications and found that it made me extremely irritable. Stinging nettle has changed my life! I take 2 in the morning and 1 at night along with turmeric and black pepper and I have found extraordinary relief that I, honestly, never thought was possible. So grateful I found this brand.
