New Look Bottle - Same Great Product!
Powerful antioxidants help support the health of the airway passages and mucous membrane. Stinging nettle, quercetin, bromelain and bitter orange offer natural help with seasonal irritants. This powerful blend enhances immune function and inhibits the release of histamine and other inflammatory compounds that initiate the sneezing, swelling and itching of allergic reactions.
HistaBlock can be used to safely manage allergy symptoms and support breathing, without the side effects commonly associated with over-the-counter and prescription antihistamines, decongestants and nasal sprays.
