lactuca sativa whole

Lactuca sativa whole is an allergenic extract derived from the garden lettuce plant, utilized as a diagnostic agent in clinical allergy testing. The extract contains a comprehensive profile of proteins from the whole plant, which, when introduced to the skin of a sensitized individual, cross-links allergen-specific immunoglobulin E (IgE) antibodies on the surface of mast cells and basophils. This interaction triggers the release of inflammatory mediators like histamine, resulting in a visible wheal-and-flare reaction that confirms hypersensitivity to lettuce. According to DrugBank, this entry represents a specific pharmaceutical preparation used to identify allergic sensitivities in patients.
