The COVID-19 pandemic has posed an unprecedented challenge to global health. Classical homeopathy may have a role to play in alleviating this burden. The objective of this study was to curate data on the treatment effect of classical homeopathy for COVID-19 in a real-world scenario to guide future scientific investigations.


Classical homeopaths from the International Academy of Classical Homeopathy (IACH) were asked to provide details on cases they treated by filling out a standardized questionnaire. COVID-19 cases were defined according to World Health Organization (WHO) criteria as suspected/probable/confirmed cases, with intervention provided being either stand-alone classical homoeopathy or combined with conventional therapy for COVID-19. Cases were followed up with main outcomes being ‘improved’, ‘not improved’ or ‘progressed’ post-treatment. Details of the homeopathic remedies used and main symptoms at the presentation were gathered. Factors associated with main outcomes were investigated with correlational and regression analyses.


367 patients (male 166, female 201) met eligibility criteria (mean age 42.75 years). The mean follow-up period was 6.5 (standard deviation, SD=5.3) days. 255 were confirmed COVID-19 cases, with 61 probable and 51 suspected cases, respectively. The most used remedy was Arsenicum album. Over 73% of COVID-19 patients (and about 79% of severe cases) improved under classical homeopathic treatment. The number of remedies required per individual was negatively correlated to improvement (P< 0.01). Fever, the most common symptom at presentation (74.4%), was associated with an increased likelihood of improvement (P<0.01). Improvement was negatively associated with advanced age, but not associated with sex (P<0.01).


This study suggests that classical homeopathy was associated with improvement in COVID-19, including severe cases. Despite limitations from study design and data sources, our findings should prompt further studies on the role of classical homeopathy in the management of COVID-19.
