Allergy velvet is a disease condition caused by hypersensitive reaction of our body’s immune system to pollen produced by velvet grass. Pollens are famous for producing severe allergic reactions in people. Since they are aeroallergens they usually cause symptoms such as running nose, asthma, watery eyes, sneezing, itching etc. Like in other immune reactions, here also, Ig E antibodies are responsible for causing such adverse reactions when the body is exposed to the particular allergen. Skin tests as well as blood tests are available for determining allergy velvet. Skin tests are more sensitive and less expensive.
