It is served as a food, as special additives in cosmetology, and for the treatment of many diseases.

It is imagined that this plant was brought from the south-western Asia and its helpful properties have led to the prompt spread of onion all around the world. However, not always we can observe only benefit of this plant; seldom people have an allergy to this product.

The Reasons of Onion Allergy

The defense of the immune system is the main reason of the development of hyperactivity, which negatively perceives protein of the vegetable and rejects it by producing antibodies.

Another significant point is the hereditary factor: if one parent possesses the allergy, the child has 50% of the probability of developing this disease. But when both parents have onion allergy, the risk may be 90%. The allergic reaction is able to occur not to the vegetable itself, but to the chemicals that were used to treat the onions for active growth and better safety.

Besides, unbalanced diet of women during pregnancy can induce one more possible reason for the occurrence of allergy.

Frequent use of onions in large quantities can cause the production of antibodies of a child to this product even before his birth: this kind of allergy is observed among the babies up to 12 month old, therefore, these vegetables are even forbidden for children up to 8 months.

After 8 months, the kid can eat the onion, but it must be undergone through the heat treatment. 3 years old children are allowed to eat fresh onions, but it is more reasonable at once to check the existence of the allergen, because a huge percentage of people have an individual intolerance to this vegetable.

In addition, people who have hyperacidity should not use onions too, because they can irritate the digestive organs and even increase the degree of acidity. People with kidney problems, liver and gastrointestinal tract also exclude the onions from their ration.

  •  in some cases, the illness is accompanied by asthmatic syndrome, Kvinke edema (extensive urticaria), and anaphylactic shock. These conditions are dangerous for life, so it is substantial to call an ambulance as quick as possible.

Each person has individual manifestations of allergy symptoms. Special attention should be addressed to the acute attack of allergy. When the first symptoms of the sickness appear, the intensive therapeutic interventions should be used instantly.

Onion Allergy Treatment


First of all, allergy treatment should be started with a general survey of the patient. It is significant to diagnose an allergic reaction particularly to an onion allergen, by taking the blood test.

After the diagnosis the doctor must prescribe antihistamines, such as Dimedrolum, Ketotifen, Claritin and Diazolin, but only the children’s dosage is used. Dimedrolum is prescribed in very severe cases.

It should be admitted, that the effects of the medicine are differ from one person to another. Thus, the same drug can be helpful and useless depending on the individual peculiarities of the organism.

Therefore, if taking of antihistamine doesn’t bring any positive results, the patient should consult the specialist and change the remedies.

It is forbidden to treat allergies alone, as intolerance to different medications can cause side effects; more rational is to ask physician and an allergist for a help.

Doctors can assign homeopathic remedies, which have a range of advantages:

• the effectiveness of medication without increasing the dose;
• they are not addictive;
• the development of the body’s resistance to allergens.

Nevertheless, it is vital to follow the dosage remedy very strictly to avoid negative effects.

A complete rejection of all types of onions is the best preventive measure that will protect people from symptoms of an allergic reaction.

The onion is possible to eat but after the complete heat treatment, then it is less harmful to the person with this allergy. If there were still deviations from the diet, the patient should drink sorbents, for example, activated carbon or enteros gel.

They are able to eliminate the allergen from the body quickly through the gastrointestinal tract.

Furthermore, such drugs block the action of the allergen, and do not allow it to be absorbed into the human blood.
