The invention discloses a 
mouth wash. The 
mouth wash is prepared through the steps that pseudo-
ginseng, wild chrysanthemum flowers, 
honeysuckle, mint and deionized water are proportionally mixed, then the mixture is smashed through a smashing 
machine, filtered and subjected to 
reflux condensation in 100 DEG C boiling water, 
reflux is kept, standing is performed for 18-24 h, 
centrifugal filtration is performed again, extract is condensed out, 
chlorhexidine, 
essential oil, polyoxyethylene hydrogenated 
castor oil, 
sodium monofluorophosphate and deionized water are mixed, the mixture is stirred for 60 min in a stirring 
machine at the rate of 1000 rpm at 80-90 DEG C, the extract which is condensed out is added, the mixture continues to be stirred and then is cooled, the PH value is regulated to be about 7 through a PH 
regulator, and the product is obtained. The novel 
mouth wash can prevent breeding of dental 
bacteria, eliminate ozostomia, clear away heat and toxic materials, disperse swelling and stop bleeding, prevent sensitivity and the like.
