allergy to lilac

Cross reactions

Once, a friend and daughter drove into our country house. A child of seven years old is sociable and purposeful. Dreams of becoming a cook. Everything that comes to hand cuts into soup.

And then just the lilac blossomed. The lilac has a magical property, all who see its flowers, are drawn to them – touch, smell, pluck. Children are no exception.

Yes, that would be nice. But the baby was allergic to birch. Neither I nor the girl’s mother heard about cross-reactions at that time. There is nothing to worry about – the birch has faded. The more we were surprised when the child’s lip was swollen. This is an allergic reaction. But what for ?

A little panic, a little tears and an antihistamine. We solved the problem, but thought hard. It turned out that birch pollen and lilac pollen are somewhat similar, and the allergy immune system sometimes confuses them. So I found out that there is an allergy to lilacs.

More than 2000 varieties of lilacs are growing all over the world, among which there are varieties without a characteristic lilac smell. Lilac lives for more than a hundred years. And she owes her name to the chaste nymph Siringa from Greek mythology.

In a panic, the nymph escaped from the god Pan and turned into a reed. It would seem, where does the lilac? But apparently there is still some kind of connection. The Greeks know better.

Insects pollinate lilacs – in this allergy sufferers. There will be little pollen in the air. Just do not bring lilac home. Outside the city, drinking tea in the shade of lilac is also not worth it.

If lilac pollen is more or less tolerable, then with essential oils it will be worse. Beautiful, fragrant flowers, a source of allergy-sensitive essential oils. Be careful – a runny nose or even bronchospasm can occur.

By the way, the lilac begins to bloom when the birch finishes blooming. If there is no heavy rain, birch pollen may remain on the leaves and flowers of lilacs.

Another fact, maybe someone will come in handy. A familiar allergist said she noticed an interesting pattern. Allergy sufferers who respond to plant essential oils, including lilacs, react to Flixonase nasal spray. I’m not kidding. Be careful.

Causes of a Lilac Allergy

  • Allergy. If you already have an allergy to trees, herbs, shrubs: olive, birch, ash, privet, jasmine, forsythia, phleum; hodgepodge, plantain, gauze.
  • Heredity. Allergy susceptibility is inherited;
  • Psychology. Yes, stress is not only an ulcer;
  • Hormones. Hormonal disruptions in the body;
  • Diseases – chronic and infectious;
  • Atopic dermatitis. Proteins can penetrate through atopic skin;
  • Pseudo-allergic reactions – to the smell of lilac.

Lilac proteins and cross-reactions

Lilac proteins and cross-reactions

Botanists rank lilacs in the Olive family. The main protein of plants of the olive family is Ole e 1. The same family has many other plants that are similar to lilac in pollen composition.

  • Olive;
  • Ash;
  • Forsythia
  • Fontanesia
  • Phyllorrhea;
  • Privet;
  • Jasmine;
  • Linocier.

The major (main) protein of lilac – Syr v 1 belongs to the family Ole e 1. Also in the pollen of lilac there are minor proteins: profiling and polcalcin.

Such a protein composition can provoke cross-reactions with other plants: with pollen from the buciferous family, cereal and meadow grasses.

  • Rhinocytogram – a cytological examination;
  • Fadiatop – ImmunoCap method. Determines whether the symptoms relate to allergies or not;
  • Provocation test.



An allergy to the major protein of the lilac Syr v 1 – Ole e 1 should be treated with Allergy immunotherapy (AIT).

Medicines for ASIT are in the Spanish drugs DIATER, Inmunotek (Oraltek).

Symptomatic (drug) treatment

  • You should meet the allergen as little as possible. If where lilac grows, then you do not need to go there;
