In short
Recent clinical trials are investigating the use of Alnus Glutinosa Pollen, commonly known as alder tree pollen, as part of a mixture for allergy testing and potential treatment. This research aims to better understand and manage allergic reactions, particularly those related to tree pollen allergies. The trials focus on evaluating the effectiveness and safety of using this pollen extract in diagnostic procedures and possibly in immunotherapy for allergic conditions.

What is Alnus Glutinosa Pollen?
Alnus glutinosa pollen is a type of tree pollen that comes from the Alnus glutinosa tree, commonly known as the black alder or European alder. This tree is native to Europe and parts of Asia, and its pollen is known to cause allergic reactions in some people.
Medical Uses
While Alnus glutinosa pollen itself is not used as a treatment, it is an important component in diagnostic tests and immunotherapy for allergies. The pollen is used in:
- Skin prick tests: These tests help diagnose allergies to tree pollens, including Alnus glutinosa.
- Immunotherapy: Alnus glutinosa pollen extracts may be used in allergy shots or sublingual immunotherapy to help desensitize patients to this allergen.
Allergic Reactions
Alnus glutinosa pollen can cause allergic reactions in sensitive individuals. These reactions are typically part of a condition called allergic rhinitis or hay fever. Symptoms may include:
- Sneezing
- Runny or stuffy nose
- Itchy eyes, nose, or throat
- Watery eyes
- In some cases, asthma symptoms
These symptoms are caused by the immune system's overreaction to the pollen, which it mistakenly identifies as harmful.
Diagnosis
Diagnosis of an allergy to Alnus glutinosa pollen typically involves:
- Skin prick test: A small amount of the allergen is placed on the skin, which is then pricked. A positive reaction (a raised, itchy bump) indicates an allergy.
- Blood tests: These can measure the levels of specific IgE antibodies to Alnus glutinosa pollen in your blood.
- Nasal provocation test (NPT): This test involves exposing the nasal passages to the allergen and measuring the response.
Treatment
Treatment for Alnus glutinosa pollen allergy may include:
- Avoidance: Minimizing exposure to the pollen during its peak season.
- Medications: Antihistamines, nasal corticosteroids, and other allergy medications can help manage symptoms.
- Immunotherapy: This treatment involves exposing the patient to gradually increasing amounts of the allergen to reduce sensitivity over time. It can be administered as subcutaneous injections (allergy shots) or sublingual tablets.
Precautions and Considerations
When dealing with Alnus glutinosa pollen allergy:
- Be aware of the pollen season for alder trees in your area.
- Monitor pollen forecasts and plan outdoor activities accordingly.
- Keep windows closed during high pollen days.
- Shower and change clothes after being outdoors during pollen season.
- Consult with an allergist or immunologist for proper diagnosis and treatment plan.
It's important to note that Alnus glutinosa pollen allergy often occurs alongside allergies to other tree pollens. Your healthcare provider may test for and treat multiple allergies simultaneously.
