A food allergy is an abnormal immune response to a specific food or a component of food. The most familiar form is IgE-mediated allergy; where the immune system makes IgE antibodies to a food protein and triggers a rapid reaction in minutes to hours that can include hives, swelling, vomiting, wheeze, or in the worst cases Anaphylaxis. There are also non-IgE and mixed reactions that can be slower and involve gut or skin symptoms. The clinical pattern like timing and organs affected is crucial to tell true allergy from intolerance or sensitivity.

The current understanding is that food allergy arises from a mix of genetic predisposition and environmental factors. Family history of eczema, asthma, hay fever raises risk; skin barrier problems in infancy like atopic dermatitis are linked to later food allergy; and environmental or lifestyle factors like diet, timing of allergen introduction to babies, microbiome composition, infections, pollution and vitamin D exposure are all under investigation as contributors.

Safety first:

If someone shows signs of anaphylaxis like throat tightness, sudden breathing difficulty, fainting or collapse, drop in blood pressure, or rapidly spreading hives with breathing problems then call emergency services. Anaphylaxis is a medical emergency. Individuals with diagnosed severe food allergy should follow a management plan from their clinician and carry epinephrine as prescribed.

IMPORTANT REMEDIES:

1. Apis mellifica: Sudden swelling, red-pink puffy skin, stinging or burning pains, better from cold applications, hypersensitivity to touch. Used for hives or angioedema-type swelling following exposure.

2. Arsenicum album: Anxious, restless person with burning pains, acrid discharges, marked thirst for small sips, and symptoms often worse at night. Used where there’s vomiting/diarrhoea, burning skin lesions or extreme restlessness after food.

3. Pulsatilla nigricans: Gentle, weepy, changeable symptoms: thick, bland discharges, food-related bloating or fullness, symptoms worse in warm rooms but better in open air, and complaints that come and go. Symptoms shift easily.

4. Natrum muriaticum: People with delayed reactions, tendency to skin eruptions, salt-craving or salt-sensitivity history, and emotional sensitivity. Used for recurring skin complaints linked to foods.

5. Urtica urens:Intense stinging, nettle-like hives or prickling skin sensations, used for acute urticarial reactions.

6. Lycopodium, Carbo vegetabilis, Nux vomica, Sulphur : These remedies each have characteristic digestive and skin symptom pictures described in classical materia medica and may be selected when the patient’s overall pattern like digestion, temperament and modalities points to them. For example, Lycopodium is often used for bloating and gas with food-intolerant complaints. Carbo veg for collapse/weakness after food. Nux vomica for irritability and food-related cramping; Sulphur for chronic skin eruptions aggravated by warmth.

Always prioritize safety. If a reaction looks severe or includes breathing/circulatory compromise, use epinephrine if you have it and call emergency services first. Do not delay emergency care.
