taraxacum officinale pollen + helianthus annuus pollen + leucanthemum vulgare pollen

This product is a **combination allergenic extract biologic** composed of non-standardized pollen extracts from *Taraxacum officinale* (dandelion), *Helianthus annuus* (sunflower), and *Leucanthemum vulgare* (daisy). It has been manufactured and distributed by Greer Laboratories and is used in allergy practice for **skin test diagnosis** and **allergen immunotherapy** in patients with clinically relevant sensitization to these pollens. Its pharmacologic effect is immunologic rather than receptor-selective: diagnostically, it is intended to detect allergen-specific immediate hypersensitivity, and therapeutically, repeated exposure is intended to modulate IgE-mediated allergic responses and reduce allergen-induced symptoms in appropriately selected patients. The product was initially approved in the United States in 1968 as part of the allergenic extract category.
