Allergies are exaggerated immune responses to environmental stimuli known as allergens. Allergies are very common, and about 50 million people in North America suffer from allergies. One of the most common forms of allergies is allergic rhinitis (“hay fever”), which produces such symptoms

  • Nasal congestion
  • Itchy and watery eyes,
  • Sneeze,
  • Stuffy nose or brat
  • Scratch or sore throat
  • Throat clearance,
  • Drip cough after the nose.

The symptoms of hay fever can cause fatigue and lethargy. Other types of allergies can affect the skin (itching and itching). Allergic shock is a serious form of allergic reactions that can be life-threatening. In an allergic shock, there is swelling in the throat and shortness of breath. Asthma is also associated with allergies in many cases.
