Homeopathy for Allergic Rhinitis: A Systematic Review

Area of Science:

• Integrative Medicine
• Immunology
• Pharmacology

Background:

• Allergic rhinitis (AR) significantly impacts quality of life.
• Homeopathic interventions are explored as alternative treatments for AR.

Purpose of the Study:

• To systematically review the efficacy and effectiveness of homeopathic treatments for seasonal or perennial allergic rhinitis (AR).

Main Methods:

• A systematic review of randomized controlled trials (RCTs) for homeopathic treatment of AR.
• Data extraction and risk of bias assessment by two independent authors.
• Meta-analysis performed on eligible trials, quantifying treatment effects with risk ratios (RR) and confidence intervals (CI).

Main Results:

• Eleven studies were included; most had a high risk of bias.
• Three trials using Galphimia glauca for seasonal AR showed statistically significant symptom relief compared to placebo.
• A homeopathic nasal spray demonstrated equivalent efficacy to a conventional nasal spray.

Conclusions:

• The overall quality of evidence for homeopathic interventions in AR is low to uncertain.
• Galphimia glauca or homeopathic nasal sprays may offer small benefits for AR symptoms.
• The efficacy of isopathic treatment for AR remains unclear.
