摘要

Wound healing in diabetic patients is often compromised due to excessive inflammation, oxidative stress, and impaired angiogenesis, leading to delayed recovery and increased susceptibility to complications. This study aimed to develop an emulgel formulation of guava leaf oil, derived from Psidium guajava (Myrtaceae), and evaluate its wound healing potential in nondiabetic and diabetic rats. Preliminary phytochemical analysis of guava leaf oil identified active compounds such as d-limonene, β-caryophyllene, and 1,8-cineole, which are known for their anti-inflammatory and antioxidant properties. The emulgel was formulated and assessed for physical attributes, including pH, viscosity, spreadability, and stability. The emulgel demonstrated potent antimicrobial activity, with the 1% concentration showing significant efficacy. In vivo studies revealed enhanced wound contraction in diabetic rats treated with the emulgel, supporting its role in promoting excision wound healing. These findings underscore the therapeutic potential of guava leaf oil emulgel as an effective agent for managing nondiabetic and diabetic wounds, providing a foundation for future clinical applications.
