Abstract: Medicinal plants have garnered global attention for their healing properties, particularly in nanoparticle synthesis, a method recognized for its environmental friendliness, low toxicity, and cost-effectiveness. Catharanthus roseus (Periwinkle or Sadabahar), a traditional medicinal plant abundant in tropical regions, stands out as a key player. Rich in phytochemicals, especially alkaloids, its leaves and roots have proven medicinal benefits, including anticancer and antihypertensive effects. Beyond its medicinal uses, the plant finds application in textiles, particularly medical textiles, aligning with the global trend toward sustainable practices. The green synthesis of nanoparticles using C. roseus is gaining traction due to its eco-friendly, non-toxic, and cost-effective nature compared to traditional methods. The study focused on the antibacterial activity of the extract against common pathogens, utilizing the well-diffusion method. The resulting aqueous extract exhibited notable antibacterial efficacy, particularly against Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, and Bacillus cereus. C. roseus emerges not only as a versatile medicinal resource but also as a valuable tool for eco-friendly and cost-effective applications in medicine and industry.
