From Wikipedia, the free encyclopedia

Ze339 brand herbal extracts are taken from the leaves of a unique variety (Petzell) of the butterbur (Petasites hybridus) plant. Petzell is grown on GAP-managed farms in Europe.

[edit]

Seasonal allergic rhinitis

[edit]

Ze339 is indicated for seasonal allergic rhinitis (hay fever). The ingredient has been evaluated in placebo-controlled, double-blind clinical studies. Ze339 was shown to be as effective as the antihistamines cetirizine and fexofenadine.[1][2] Against desloratadine, an improved version of loratadine, Ze339 had better efficacy in relieving congestion and other allergy symptoms.[3][4] In these studies, Ze339 was shown to be less sedating than cetirizine and fexofenadine.[1][2]

Pharmacology

[edit]

Ze339 brand extract is not an antihistamine and represents a symptomatic treatment with very different properties.[3] In-vitro studies show that petasins in Ze339 brand extract inhibit leukotriene biosynthesis and block degranulation in activated mast cells and eosinophils.[5][6]
