Clinical Studies

Allergy Relief is a homeopathic preparation for the relief of allergic rhinitis symptoms (seasonal allergies), sneezing, watery eyes and allergic reactions.


Allergy Relief Spray: Clinical Evidence

A clinical trial was carried out in 11 general practices in Switzerland2. The trial involved patients suffering from allergic rhinitis and/or hay fever for a period of at least two years and who were over the age of 18.

Allergy Relief spray was applied for 14 consecutive days, 3-5 times daily with 1-2 puffs into each nostril.

Patients had to fill out a diary recording the following symptoms: rhinorrhoea, nasal obstruction, sneezing attacks, pharyngeal irritation, coughing and irritated eyes.

A total of 63 patients with an average age of 33 years attended the trial which had been carried out from April until August.

  • At the end of the treatment, the average symptoms which had been recorded in the diaries were reduced by 30-50%. In particular, the sneezing attacks and nasal congestion had improved significantly.
  • The majority of patients experienced an improvement in their symptoms and approximately 12% of patients had noticed no change whatsoever.
  • Upon completion of the study, 55% of patients rated the spray as excellent or good for efficacy. The treating physicians also shared this judgement.
  • About 70% of patients would use the Allergy Relief spray again, thereby showing that the majority were satisfied with this treatment.
  • Almost no side effects were reported and 90% of all users rated the tolerability as good or even excellent.
