Respiratory allergies are irritation and swelling in the nose. It is caused by an overreaction of the immune system to allergens like pollen, dust mites, or mold. It can cause a runny nose, itchy eyes, sneezing, and coughing.
Allergens cannot always be avoided. Symptoms may be managed with medicines, such as antihistamines and steroids. Some people turn to natural therapies to further ease symptoms.

- Flavanoids, such as quercetin are a class of plant pigments T1-T8
- Helminth therapy is an intentional infection with hookworm or whipworms U1
- Oligomeric proanthocyanidins (OPCs) are compounds found in grape seed and pine bark extractsP1
