Abstract
Neem (Azadirachta indica) is a multipurpose tree with numerous health benefits. The antibacterial effects of the tree's numerous portions have been proved against a wide spectrum of microorganisms. The identification of bioactive compounds in this medicinal plant could lead to the development of new antibacterial treatments that are less expensive and more effective. Researchers employed Mentha aravensis to examine the effectiveness of alcoholic extracts of Mentha (Mint) on decaying teeth (Mint). Mint leaves have the same impact as chewing gums and, more importantly, they help to freshen your breath naturally. The extract, as well as the controls, were then tested microbiologically to see which concentration produced the largest inhibitory zone against Gram negative bacteria. In millimetres, the inhibitory zone was measured. A 10 mm zone of inhibition was produced using a 50 percent concentration of neem and mint extract. This was the largest zone of inhibition identified among the neem and mint concentrations studied. Neem and mint extracts showed antibacterial activity against Gram negative bacteria.
