Allergy is an over-reaction of the defense system on harmless substances. In contact with these substances, the defense system is disrupted and unnecessary and excessive antibody formation occurs.  Allergens are substances that cause allergies. In the world, 25% of people suffer from different types of allergies and it's growing steadily!

  Most common allergens

• Pollen grass and weeds and plants
• Mites

• Animal allergens
• Insects
• Food allergens

Allergens witch are transmitted by air, causes rash, red and swollen eye, hay fewer or asthma. 

Food allergies cause local and general allergic reactions and anaphylactic shock which can be very dangerous to life!

 Allergic reaction mechanism

Antibodies protect the organism from viruses, bacteria and infections.          
In an allergic person, the immune system misunderstood a certain allergen as an enemy and begins to create defense antibodies. Such antibodies, called immunoglobulin E (IgE),  they bind to mast cells which they have on  skin, nose, eyes,lungs and gastrointestinal tract. When  antibodies IgE find an allergen, they start to produce a powerful chemical of histamine. This causes an allergic reaction.  The reaction may occur immediately or after several hours. 

 For now, allergies can not be cured. Antihistamines are used to relieve the symptoms.
