Allergies are misguided reaction to foreign substances by the immune system, the body system of defense against foreign invaders and pathogens (the agents of infection). Acacia tree or babul is known for its medical treatments but might have some allergic reactions to certain individuals because of the pollens present in the tree. The symptoms includes low grade fever, sneezing, stuffy or running nose, itchy nose, watery eyes, itchy skin, sore throat, poor appetite, frequent headaches, sinus pressure and facial pain. Allergies are caused by allergens. The allergens present in Acacia Babul are Acacia Tree Pollen and are reported to cause pollinosis or strong allergic reactions. Most of the allergies are treated by avoiding whatever causes the allergy. Only when the allergic reaction is strong, an allergist is concerned.
