What is Elderberry Allergy?
An elderberry allergy is an immune response triggered by exposure to elderberry plants or their derivatives. While elderberries are sometimes used in traditional medicine and food products, they can cause allergic reactions in sensitive individuals. This condition occurs when the body mistakenly identifies proteins in elderberries as harmful, leading to the release of chemicals like histamine. Reactions can range from mild irritation to severe, life-threatening symptoms. Although rare, elderberry allergy is possible, especially in people with a history of pollen or food allergies.

Common Causes
Elderberry allergy is primarily caused by direct exposure to allergenic proteins found in elderberries. Below are the most common triggers:
- Ingestion of elderberries or products: Eating raw or processed elderberries, juice, jams, or supplements.
- Skin contact: Touching elderberry plants or leaves, which can cause localized reactions.
- Inhalation of pollen: Breathing in airborne elderberry pollen during bloom season.
- Cross-reactivity: Allergies to related plants (e.g., birch, ragweed) due to similar protein structures.
- Inhalation of dried berries: Dust or particles from dried elderberries in homes or supplements.
- Handling concentrates: Exposure to elderberry extracts or tinctures without proper precautions.
- Occupational exposure
