Nature has been a source of medicinal agents for thousands of years and an impressive number of modern drugs have been isolated from natural sources. Pisidium guajava (Guava) leaf family name is Myrtaceae. Leaf and bark extracts have in vitro antimicrobial activity mostly associated with flavonoids such as Morin glycosides, quercetin and quercetin glycosides. Antimicrobial activity of Pisidium guajava, studied from dried leaves.The chemical nature of the extract was determined and extractions of active substance from the leaves were done by using ethanol. The method of application of this herbal extract on cotton, organic  cotton and bamboo fabrics using citric acid as cross-linking agent was processed in 80oC for 15 minutes with pH level 4.5. The antimicrobial activity of the finished cotton, organic  cotton and bamboo fabrics based on optimized process parameters was assessed against bacteria that normally exist in the textile materials like Gram positive, Staphylococcus aureus and Gram negative, Escherichia coli by paper disc method and also fabrics evaluated objectively.
