Abstract : The study aimed to formulate and evaluate a topical herbal ointment containing Phyllanthus emblica Linn. (amla) leaf extract for the management of burns and wound recovery, leveraging the plant’s documented antioxidant, antiinflammatory and collagen-promoting properties. Methanolic extract of P. emblica leaves was prepared, standardized through preliminary physicochemical and extractive value tests, and incorporated at selected concentrations into a simple ointment base using conventional fusion and trituration techniques. The finished formulations were evaluated for organoleptic properties, pH, spreadability, washability, homogeneity, and stability, followed by assessment of antimicrobial activity against wound-associated pathogens and in vivo wound-healing performance in excision and burn wound models in rodents. The present work focuses on the formulation and evaluation of a topical herbal ointment containing Phyllanthus emblica Linn. (amla) leaf extract for the treatment of burns and cutaneous wounds, exploiting its strong antioxidant, antiinflammatory, and antimicrobial profile and its documented ability to enhance collagen synthesis via ERK1/2 activation. Fresh leaves of P. emblica were shade-dried, powdered, and extracted using a suitable hydroalcoholic or methanolic solvent system, and the extract was standardized by determining extractive values, total phenolic content, and key tannins such as emblicanin-type compounds associated with wound repair. The optimized extract was incorporated into a simple ointment base at different concentrations (for example 5–20% w/w) using the fusion method, with suitable emulsifying agents and humectants to improve spreadability, stability, and patient acceptability. In vitro antimicrobial activity against common wound and burn pathogens, such as Staphylococcus aureus and Pseudomonas aeruginosa, was assessed by agar diffusion, aiming to demonstrate improved inhibition zones relative to plain base, in line with the known antibacterial effects of Phyllanthus emblica–containing topical systems. In vivo wound-healing efficacy was evaluated in rodent excision and partial-thickness burn models by monitoring percentage wound contraction, epithelization period, and tensile strength, as well as by histopathological examination of re-epithelialization, granulation tissue formation, neovascularization, and collagen deposition. Topical application of the amla leaf ointment yielded acceptable physicochemical and stability profiles and produced significantly larger antimicrobial zones of inhibition than the placebo base, supporting its potential to reduce wound bioburden. In animal models, the optimized concentration accelerated wound contraction, shortened the time to complete epithelial closure, and increased tensile strength compared with untreated and base controls, with histology revealing denser, better organized collagen fibers and reduced inflammatory cell infiltrate. These findings collectively suggest that Phyllanthus emblica leaf–based ointment is a promising, low-cost herbal candidate for adjunctive management of burns and chronic or acute wounds, meriting further mechanistic and clinical investigations to define optimal dosing, safety, and long-term outcomes in humans.
