Evaluation of Add-On Individualized Homeopathic Medicines Products in the Treatment of Symptomatic COVID-19 Managed at Home: A Double Blind, Placebo-Controlled, Randomized, Exploratory Clinical Trial

Abstract

Homeopathy has shown promise in fighting epidemics, leading to potential applications in the COVID-19 clinical cases. To assess the impact of add-on individualized homeopathic medicinal products (IHMP) in improving clinical outcomes and time to medical discharge in COVID-19 patients. A prospective, double-blind, randomized, placebo-controlled, parallel-group exploratory clinical trial was conducted in a São Paulo state municipality, Brazil, between February and July 2021. 82 (unvaccinated) patients with confirmed SARS-CoV-2 infection and manageable mild to moderate COVID-19 symptoms were randomly assigned to placebo or IHMP groups. Utilizing unique global COVID-19 symptom scores, a symptom assessment was performed. Statistical analysis involved 68 patients (36 IHMP; 32 placebo). No significant initial disparity existed in total COVID-19 symptom scores between the groups. The IHMP group exhibited a significantly shorter mean time from initial appointment to medical discharge compared to placebo (p < 0.05: IHMP 74.5 hours (+/- 57.47, 95% CI: 55.73-93.27); placebo 137.42 hours (+/- 87.85, 95% CI: 106.98-167.86)). Employing the chi-square trend test at selected time points (74.5 and 137.42 hours, corresponding to mean discharge times), COVID-19 scores demonstrated sustained IHMP-associated reductions (p < 0.05). COVID-19 symptom scores and time to medical discharge were significantly reduced by treatment with IHMP compared to placebo, suggesting a potential role for IHMP in managing mild to moderate COVID-19 symptoms at home.
