Homeopathy, Ayurveda and allergy: an honest answer to the question everyone asks me

Why the question comes up in every consultation

In India, homeopathy and Ayurveda are often the first line, not the last resort. They are available, affordable, familiar, and they carry a reputation for being gentle — which matters enormously to a parent weighing up giving a five-year-old a steroid inhaler. By the time someone arrives at an allergy clinic they have frequently spent two or three years, and a considerable amount of money, on other treatment.

I want to be clear about the tone of what follows. Nobody should be made to feel foolish for what they have already tried. The useful question is not "why did you do that" but "what did that treatment actually do, and what would this one do differently".

The confusion about small doses

Immunotherapy is sometimes explained to patients as "like homeopathy, but medical". This is where the misunderstanding starts, so it is worth taking apart.

Allergen immunotherapy uses precisely measured amounts of a specific, standardised allergen extract — the exact thing your skin prick test identified. The dose starts small and increases over months to a maintenance level, which is then sustained for three years. The increasing dose is the entire mechanism: it retrains the immune response, shifting it away from the IgE pathway. There is a measurable target dose, and going below it does not work.

Homeopathic preparation uses serial dilution, on a principle that greater dilution produces greater potency. At common dilutions, no molecule of the original substance remains. The direction of dose is the opposite, and the underlying principle is different.

They are not two versions of one idea. They are two different ideas that both happen to involve the word "small".

What the evidence shows

Allergen immunotherapy has been studied in large randomised controlled trials for grass, house dust mite and several other allergens. It reduces symptoms and medication use, and — unusually among allergy treatments — the benefit persists for years after the course is finished. It is the only treatment we have that modifies the disease rather than suppressing the symptom. It also carries real risks, which is why it is prescribed after testing and not before, and why it is not right for everyone. That part is covered on the immunotherapy page.

Systematic reviews of well-designed studies of homeopathy in allergic disease have not demonstrated an effect beyond placebo. This is not a claim that patients did not feel better — many report that they did. Allergic rhinitis fluctuates naturally with season, humidity and exposure, and placebo effects in symptom-scored conditions are substantial and genuine. Feeling better is real. It is the attribution that is uncertain.

Ayurveda, specifically

Ayurveda is a broad system and deserves a more careful answer than homeopathy, because parts of it overlap with advice I would give anyway. Nasya and saline nasal irrigation, steam, avoiding known triggers, attention to sleep, diet and weight, and breathing practice in pranayama — these are reasonable, low-risk, and some have supportive evidence in their own right. I have no objection to a patient continuing them alongside treatment, and I would rather know about it than not.

Two cautions, and they are serious ones. First, some marketed "herbal" and "Ayurvedic" preparations for asthma and skin disease contain undeclared corticosteroids. Patients taking them for months arrive with the features of long-term systemic steroid exposure, believing they have taken nothing but herbs. If you are taking something and it works remarkably well and remarkably fast, bring the packet. Second, delay itself causes harm: a child whose asthma is treated symptomatically for three years while inflammation continues can lose lung function that does not come back.

About steroid fear

Behind this question there is almost always another one: a fear of steroids. It deserves a straight answer. Inhaled steroids are not the same as the oral or injected steroids that cause weight gain, diabetes and bone loss. The inhaled dose is measured in micrograms and delivered to the airway rather than the bloodstream. The effect on a child's growth is small — and untreated asthma affects growth too, as well as school attendance, sleep and lung development.

The more useful comparison is not "steroid versus no steroid" but "a small daily preventer dose versus repeated courses of oral steroids and nebulisation every time it flares". The second of those is the higher steroid exposure, by a wide margin.

Bring what you are already taking

Every packet, every bottle, including anything herbal or homeopathic. Nothing is judged, and it genuinely changes what I advise.
