As I written in last post that I will start posts (information) about the treatment & various techniques, which were used in home, against to the diseases. NOT against to severe diseases but if we don't look out on these diseases it will become severe one. Topic of today is Allergy, very common and simple disorder of our immune system against allergens (present in environment). Now question arises what are these,.... allergens??? Before this we have to know about brief knowledge about Allergy.
Allergy: - It is a disorder of our immune system against those environmental substances which are non-acceptable by our immune system like odour/smell (odour/smell of flower), allergy against food materials etc... (A simple definition)Biologically: - Allergy is one of four forms of hypersensitivity and is called type I (or immediate) hypersensitivity. It is characterized by excessive activation of certain white blood cells called mast cells and basophils by a type of antibody known as IgE, resulting in an extreme inflammatory response. Common allergic reactions include eczema, hives, hay fever, asthma, food allergies, and reactions to the venom of stinging insects such as wasps and bees.
Our body's immune system is familiar to many environmental substances, if un-familiar substances are faced by our immune system then Allergy may occur.In condition of Allergy, if our body comes in contact of foreign substance, our body release chemical like Histamin etc, which are responsible to the changes in our immune system.
