Lamb's quarters (Chenopodium album) is a common wild plant found in many temperate regions across the world. While it’s sometimes consumed as a leafy green in foraging and traditional cuisines, it is also a known source of airborne allergens. The plant produces fine, powdery pollen during the summer, which can become airborne and cause allergic reactions such as hay fever, nasal congestion, and asthma symptoms in sensitive individuals. Due to its wide distribution and allergenic potential, lamb's quarters is often included in inhalant allergy panels.
It may lead to symptoms like sneezing, nasal congestion, itchy eyes, and asthma-like breathing difficulties during its pollen season.
