SBP 07 - Comparative Efficacy of Fresh Aloe vera Extract and Aloe vera Powder, USP with Zinc nanoparticles vs. with Clindamycin as Cream against Staphylococcus epidermidis, Staphylococcus aureus, and Streptococcus pyogenes

This quantitative research was done to determine the antibacterial properties of Aloe vera extract and Aloe vera powder in combination with Zinc nanoparticles and Clindamycin as cream against Staphylococcus epidermidis, Staphylococcus aureus, and Streptococcus pyogenes. The researchers formulated an antibacterial cream following the formula which used distilled water, EDTA, glycerin, carrageenan, olive oil, Tween 80, Stearic acid, Benzoic acid, combined with the aloe vera extract, aloe vera powder, zinc nanoparticles, and Clindamycin to determine their synergistic effect against the test microorganisms. To determine the antibacterial properties of the cream formulations, the researchers used the Agar Well Diffusion Method and Disc Diffusion Assay method. The experimental groups employed four combinations of cream namely: Aloe vera extract plus Zinc nanoparticles, Aloe vera extract plus Clindamycin, Aloe vera powder plus Zinc nanoparticles, and Aloe vera powder plus Clindamycin. The results of the study verified that Aloe vera extract has antibacterial capacity and synergistic activity with zinc nanoparticles (minimal) and Clindamycin. The results are open to possibilities in the formulation of other dosage forms using aloe vera extract in higher concentrations and a combination of aloe vera extract with other plant extracts that can be used in the treatment of many bacterial infections specifically in the treatment of Acne vulgaris. 

This project was undertaken to explore innovative and effective treatment options for managing infections caused by Staphylococcus epidermidis, Staphylococcus aureus, and Streptococcus pyogenes, which are common pathogens associated with skin infections. With the growing concern of antibiotic resistance and the limitations of conventional treatments, we aimed to evaluate the potential of combining natural remedies like fresh Aloe vera extract and Aloe vera powder, USP, with emerging nanotechnology-based agents such as zinc nanoparticles, and compare their efficacy to a widely used antibiotic, clindamycin. By leveraging the antimicrobial, anti-inflammatory, and wound-healing properties of Aloe vera alongside the potential of zinc nanoparticles and traditional antibiotics as a broad-spectrum antimicrobial, we sought to identify effective, affordable, and sustainable treatment alternatives. This study aims to reduce the dependency on conventional antibiotics while addressing public health challenges posed by drug-resistant bacteria, ultimately advancing efforts in combating antimicrobial resistance and improving the quality of skin infection management. Our study compares the efficacy of two innovative formulations: fresh Aloe vera extract and Aloe vera powder, both combined with zinc nanoparticles, versus traditional clindamycin cream. Aloe vera brings its natural healing and soothing effects.

In conclusion, our research study highlights the remarkable potential of combining natural plant-based remedies, such as Aloe vera, with modern nanotechnology and traditional antibiotics to combat bacterial skin infections. Formulations using Aloe vera extract or powder enriched with Clindamycin demonstrated significant antibacterial efficacy, which opens to possibility of using plant sources to cure diseases. This innovation not only offers an effective solution but also addresses pressing issues like antibiotic resistance, affordability, and accessibility in low-resource settings. We recommend the use of aloe vera extract in increased concentrations and to combine the extract with other plant extracts to test its antibacterial potential. Our work bridges the gap between nature and science, offering hope in the fight against bacterial skin infections.
