Ambrosia chamissonis pollen

Ambrosia chamissonis pollen, also known as Silver Burr Ragweed pollen, is a highly allergenic substance derived from the *Ambrosia chamissonis* plant, a species of ragweed native to the western coastal regions of North America. This wind-borne pollen is a significant cause of seasonal allergic rhinitis (hay fever) and dermatitis in susceptible individuals. Upon inhalation, it triggers an immune response, leading to symptoms such as sneezing, runny nose, itchy eyes, and skin rashes. In some cases, exposure can exacerbate or induce asthma. The allergenic properties are attributed to specific proteins within the pollen grains. As an active ingredient, it is utilized in allergen immunotherapy to desensitize individuals to ragweed pollen.
