Antibacterial Properties of Topical Herbal Formulations Containing Euphorbia neriifolia, Diplazium esculentum, and Coleus blumei Extracts

Year: 2026

Type: article

Abstract: Bacterial skin infections remain a common health concern in tropical regions like the Philippines. To address the growing resistance to traditional antibiotics, this study developed and evaluated herbal products (soap, cream, and lotion) infused with KaPaMa extracts from Euphorbia neriifolia (Karimbuaya), Diplazium esculentum (Pako), and Coleus blumei (Mayana). The antibacterial activity of the herbal products at 0.2%, 0.4%, and 0.8% concentrations was evaluated using the disc diffusion assay against Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, and Acinetobacter baumannii. Results revealed that the lotion formulation demonstrated the strongest antibacterial activity against all tested bacterial species, with 0.4% concentration with the largest zones of inhibition. Cream formulations also demonstrated antibacterial effects, particularly the 0.8% concentration. Soap formulations showed minimal antibacterial activity at all concentrations comparable to the soap base. The findings of this study show that KaPaMa herbal cream and lotion can fight common skin infections. This could be used as an alternative skincare product using locally abundant plants.
