The goal of this study is to develop a formula and test its efficacy against bacteria found in the oral cavity. The goal of this study is to develop and test herbal mouthwash, as well as to determine its efficacy against oral microbial load. Water was removed from the plant materials that were collected. the plant components were collected and watersoluble compounds were removed. The antibacterial activity and physicochemical properties of prepared mouthwash were also tested. The present mouthwash possesses a good antibacterial property. The findings of the stability research back up the effectiveness of the preparation. Mouthwash is currently a liquid preparation that usually comprises antibacterial and antiseptic ingredients. These treatments can be used to limit microbial growth in the mouth, but they can also be utilised for other reasons, such as analgesic, anti-inflammatory, or anti-fungal properties. The ingredient contains turmeric, clove oil, honey and Peppermint oil were chosen for mouthwash, and the final formulation was tested for antimicrobial activity against Staphylococcus aureus and S. salivarius cultures, as well as physical properties such as pH, colour, and stability. The presence of mouthwash has a strong antibacterial effect. Mouthwash is a liquid preparation that generally contains antibacterial and antiseptic compounds, and it is stable in a variety of temperatures. This solution can be used to minimise microbial growth in the mouth, as well as for other purposes such as analgesic, anti-inflammatory, or antifungal activities.
