ambrosia trifida pollen + ambrosia artemisiifolia pollen

A **combination allergenic extract** composed of pollen from *Ambrosia trifida* and *Ambrosia artemisiifolia* used in allergen immunotherapy and diagnostic allergy testing for ragweed sensitization. This product is marketed as a non-standardized biologic allergen extract for **skin test diagnosis** in patients with a clinical history of ragweed allergy and, after dilution, for **subcutaneous immunotherapy**. Its therapeutic effect is based on controlled exposure to ragweed allergens to modulate the allergic immune response, while its diagnostic use relies on provoking an IgE-mediated hypersensitivity response in sensitized individuals. The product has been marketed by Greer Laboratories and is distinct from the approved sublingual short ragweed tablet product that contains only *Ambrosia artemisiifolia*.
