Formulation and Comparison of Herbal Gels Containing Essential oils and their Antimicrobial Evaluation.

Abstract

Objective: The current study aimed to formulate and evaluate herbal gels con-taining essential oils for the treatment of infection caused by microbial species, i.e., S. au-reus, E. coli, P. aeruginosa, and B. subtilis. These species are also responsible for acne directly and indirectly.

Material and methods: The gels were prepared using a gelling agent with 1% Carbopol-940, and they were further evaluated for physical appearance, drug content, in-vitro drug release, viscosity, extrudability, pH, and spreadability. Further, anti-microbial screening was done with various microbial species.

Results: Studies revealed that the gel was highly effective against the selected species ex-cept for the fungal strain. ZOI was observed ranging from 3.1 ± 0.01 mm to 13.4 ± 0.14 mm. The maximum ZOI was observed at 13.4 ± 0.14 mm against S. aureus. The physical properties of the gel satisfied the standard parameters.

Conclusion: The prepared herbal gel was found to have highly promising activity against bacterial species associated with bacterial infection but in a dose-dependent manner. How-ever, more research is required.
