The plates will be left at room temperature from three to four days. Scraping out of the crystal powder of the extract from the plates will be carried out \[27\].~The peppermint mouth rinse that was used in this study had 1% peppermint base, 10% xylisorb, 5% glycerin, 1% Tween 20%, 5% alcohol 96%, 0/18% methyl paraben, and 0/02% propyl paraben \[28\].~Similarly, green tea plus peppermint mouthwash will be prepared at the same way but by adding 50% green tea leaves and 50% peppermint in the extract."
