Tilia americana pollen

Tilia americana pollen is an allergen extract derived from the pollen of the American basswood or American linden tree. It is primarily utilized as a diagnostic agent in clinical allergy testing, such as skin prick tests or intradermal tests, to identify hypersensitivity in patients suspected of having seasonal allergic rhinitis or asthma triggered by this specific tree species. The extract contains the allergenic proteins native to the Tilia americana species, which, upon exposure to the skin of a sensitized individual, cross-link IgE antibodies on mast cells and basophils. This interaction triggers the release of histamine and other inflammatory mediators, leading to a localized wheal-and-flare reaction that serves as a positive indicator of allergic sensitivity.
