Sodium carboxymethylcellulose sodium, sodium lauryl sulfate, glycerin, colloidal silicon dioxide, silicas, sodium cocoyl iodate, sodium dodecyne and sweetener, which are commonly used to make toothpastes for comparison of the degree of halitosis. , A perfume, a coloring agent and the like were used to make a control dentifrice, and an experimental dentifrice containing 0.01% by weight of the motherwort extract was prepared

Fifty men and women without dental caries were selected and cross-over test was performed for the beverage. The commercially available garlic powder was dispersed in water, allowed to stand for 24 hours, and diluted so that the measured value of the halimeter was 700 ppb or more. The diluted solution was used as a source of bad breath. After 30 minutes of gagging with 15 ml of garlic diluted solution, the degree of halitosis was measured with a half-meter after one minute, and then groomed for 30 seconds to 1 minute using a control group and an experimental group of toothpaste. After 1, 5, and 30 minutes of rinsing, the degree of halitosis was measured with a halimeter meter to measure the persistence of halitosis suppression. The results are shown in the following table.
