Allergy is a disorder of the immune system often also referred to as atopy. Allergic reactions occur to normally harmless environmental substances known as allergens; these reactions are acquired, predictable, and rapid. Strictly, 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.

Mild allergies like Hay fever are highly prevalent in the human population and cause symptoms such as allergic conjunctivitis, itchiness, and runny nose. Allergies can play a major role in conditions such as Asthma. In some people, severe allergies to environmental or dietary allergens or to medication may result in life-threatening anaphylactic reactions and potentially death.

A variety of tests now exist to diagnose allergic conditions; these include testing the skin for responses to known allergens or analyzing the blood for the presence and levels of allergen-specific IgE. The orthodox treatments for allergies include allergen avoidance, use of anti-histamines, steroids or other oral medications, immunotherapy to desensitize the response to allergen, and targeted therapy. The medical specialty concerned with allergies is allergology.

Risk factors for allergy can be placed in two general categories, namely host and environmental factors... Host factors include heredity, sex, race, and age, with heredity being by far the most significant. However, there have been recent increases in the incidence of allergic disorders that cannot be explained by genetic factors alone. Four major environmental candidates are alterations in exposure to infectious diseases during early childhood, environmental pollution, allergen levels, and dietary changes.

Common symptoms of allergy
Affected organ	Symptom
Nose	swelling of the nasal mucosa (allergic rhinitis)
Sinuses	allergic sinusitis
Eyes	redness and itching of the conjunctiva (allergic conjunctivitis)
Airways	Sneezing, coughing, bronchoconstriction, wheezing and dyspnoea, sometimes outright attacks of Asthma, in severe cases the airway constricts due to swelling known as angioedema
Ears	Feeling of fullness, possibly pain, and impaired hearing due to the lack of Eustachian tube drainage.
Skin	rashes, such as eczema and hives (urticaria)
Gastrointestinal tract	abdominal pain, bloating, vomiting, Diarrh

Many allergens such as dust or pollen are airborne particles. In these cases, symptoms arise in areas in contact with air, such as eyes, nose and lungs. For instance, allergic rhinitis, also known as Hay fever, causes irritation of the nose, sneezing, and itching and redness of the eyes. Inhaled allergens can also lead to Asthmatic symptoms, caused by narrowing of the airways (bronchoconstriction) and increased production of mucus in the lungs, shortness of breath (dyspnea), coughing and wheezing.

Symptoms of food allergy include abdominal pain, bloating, vomiting, diarrhea, itchy skin, and swelling of the skin during hives. Food allergies rarely cause respiratory (Asthmatic) reactions, or rhinitis.

Insect stings, antibiotics, and certain medicines produce a systemic allergic response that is also called anaphylaxis; multiple organ systems can be affected, including the digestive system, the respiratory system, and the circulatory system. Depending of the rate of severity, it can cause cutaneous reactions, bronchoconstriction, edema, hypotension, coma, and even death. This type of reaction can be triggered suddenly, or the onset can be delayed. The nature of anaphylaxis is such that the reaction can seem to be subsiding, but may recur throughout a prolonged period of time.

Substances that come into contact with the skin, such as latex, are also common causes of allergic reactions, known as contact dermatitis or eczema. Skin allergies frequently cause rashes, or swelling and inflammation within the skin, in what is known as a "wheal and flare" reaction characteristic of hives and angioedema.

Sulfite allergy Homoeopathic Approach:
Homoeopathic medicines act by:
Relieving the symptoms:
Preventing exacerbations (attacks)
Controlling and curing the disease process

Relieving Symptoms: Homoeopathic medicines offer considerable relief symptoms of Allergic patients
Preventing exacerbations (attacks):
Homoeopathic medicines prevent any exacerbations at fist prolonging the time between episodes and later preventing their occurrence leading to permanent cure. Controlling and curing the disease process: Homoeopathic medicines offer permanent cure in allergic conditions they act by curtailing the individual's immune response against allergens, thus decreasing their hypersentivity towards triggering stimuli. The development of allergic conditions is multifactorial and depends upon interaction between susceptible genes and environmental factors. Thus homoeopathy with its deep acting constitutional remedies offers excellent results.

Our medicines have not to be taken for life time. Once cured the patients develops immunity towards the triggering stimulus which is maintained even after medication is stopped.
