Lambsquarters pollen is a well-known allergen as it is abundant, widespread, and highly allergenic. The pollen is dispersed by wind, making it difficult to avoid for those with hay fever or other respiratory allergies. In fact, it is one of the leading causes of weed-related allergies in the United States, affecting roughly 1 in 10 people.
For those who are allergic to Lambsquarters pollen, exposure can lead to symptoms such as sneezing, runny nose, itchy eyes, and even more severe respiratory issues. It is particularly problematic for those who already have asthma, as it can trigger an asthma attack.
Researchers have been studying Lambsquarters pollen in order to better understand the immune response it triggers and to develop more effective treatments for pollen allergies. One recent study found that the pollen of Lambsquarters has a particularly high content of a type of protein known as profilin. Profilin is a known allergen in many plant species and is often responsible for cross-reactivity between different types of pollen.
Those suffering with summer hayfever and allergy symptoms are strongly encouraged to schedule an allergy test to find out exactly which allergens are causing their symptoms.
