An allergy is a condition of unusual sensitivity of one person to one or more substances which may be harmless to the majority of other individuals.
In the allergic person, the allergic substance, known as an allergen, is viewed by the brain as a threat to the body's
well-being.

What can be treated?

Not just hayfever .. and not just food intolerances! When in the presence of an allergen, blockages occur, disrupting the normal energy flow in the body. The energy blockage causes interference in the communication between the brain and the body, which is often the first step in developing an allergic response. Many of the chronic illnesses today are due to allergies and many unexplained symptoms may be due to a sensitivity or intolerance to food & drink. Environment factors including computer screen radiation or wood, can also cause illness and an autoimmune response, giving rise to long term illness all of which can be treated with NAET. 

What are allergies?
Medical scientists are still researching to find the exact cause and nature of allergies, but may not have all the answers for years to come. From a Western medical point of view, an allergy is an over-reaction by the immune system. Therefore, for our purposes, an allergy is defined in terms of what a substance does to the energy flow in the body. When contact is made with an allergen, it causes blockages in the energy pathways called meridians, or we can say, it disrupts the normal flow of energy through the body's electrical circuits. This energy blockage causes interference in communication between the brain and body via the nervous system. This blocked energy flow is the first step in a chain of events which can develop into an allergic response. Allergies are the result of energy imbalances in the body, leading to a diminished state of health in one or more organ system.

When a virus attacks, an amazing defense mechanism goes into action. The struggle to rid the body of the invading virus we recognize as the symptoms of illness, such as fever, coughing, aches, vomiting, fatigue, etc. These are, in fact, signals of the battle that is going on inside the body as it tries to throw off the invading toxins-producing virus.

Untreated, the symptoms increase with serious results. Similarly, continuous contact with an allergen produces toxins in the body, causing similar reactions to occur. An undiagnosed or undetected allergic condition will produce conditions that are equally serious. Many times the allergic reactions produce symptoms that mimic other conditions.

Respiratory problems like bronchitis, pneumonia, and asthma, circulatory problems like chest muscle pains, poor circulation, rapid heartbeats, heart irregularities, gastro-intestinal problems like indigestion, acute abdominal pains, acute appendicitis, bloating, constipation, diarrhea and ulcers, genito-urinary problems like kidney and bladder infections, prostate troubles, pre-menstrual syndromes and post-menstrual disorders, impotency, infertility, muskulo-skeletal problems like unexplained pains anywhere in the body, various types of headaches, backaches, arthritis, restless leg syndrome, brain symptoms like brain fog, depression, anger, attention-deficit disorders, hyperactivity, learning disorders, skin problems like eczema, boils, slow healing wounds, environmental reactions like multiple chemical sensitivity, allergy to pollens, perfumes, animal danders, carpets, building materials, etc... just about any health condition could be merely a symptom of underlying allergies.

  But for some people, accidental contact with an allergen can produce terrifying toxins in the body that result in clearly diagnosed illness just as though that person had taken a poison. Diagnosis for either is not easy, but the milder the complaint, the harder it is for the patient to get good treatment. For instance, how do you treat a person for "feeling out of sorts, for a slight loss of memory, for a slight but persistent sore throat or cough, for a nagging, dull headache that does not respond to pain medications, for a persistent backache or a tingling feeling in the arms and hands that cannot be diagnosed by a neurologist?" Some of these unfortunate people have seen their physicians so many times that they cannot tell you how often they have been ignored, diagnosed as suffering from a "nervous disorder" or been labeled a hypochondriac.
