Formulation and evaluation of antimicrobial herbal ointment containing Colocasia esculenta

Herbal medicine refers to the use of any plant's seeds, berries, roots, leaves, bark, or flowers for medicinal purposes. The objective of the study was to formulate and evaluate the antimicrobial herbal ointment from ethanolic extracts of leaves of Colocasia esculenta. The ointment base was created, and the ointment was made by using the levigation process to incorporate the extract into the base. It was assessed for physicochemical criteria such as colour, odour, pH, spreadability, extrudability, consistency, diffusion studies, solubility, and washability once the formulation was completed. The formulation was further tested for stability at various temperatures, revealing no differences in irritancy, spreadability.
