Malaria remains a significant public health issue in Zimbabwe's remote areas, where traditional healing practices are prevalent and often used alongside conventional medical interventions. A randomized controlled trial was conducted with participants randomly assigned to receive either a combination of traditional remedies and standard antimalarials, or standard antimalarials alone. Data collection included surveys for symptom reporting and biological samples for diagnostic testing. During the twelve-month study period, there was a notable reduction in malaria cases among those using traditional healing practices (52% fewer cases compared to controls), with an uncertainty interval indicating a robust effect size of -0. 47 standard deviations. Traditional healing practices showed promise as complementary treatments for malaria but required further validation and integration into healthcare systems. Further research should explore the mechanisms underlying traditional remedies' efficacy, alongside developing guidelines for safe and effective use in conjunction with conventional medicine. Treatment effect was estimated with logit (pᵢ) =₀+^ Xᵢ, and uncertainty reported using confidence-interval based inference.
