Tips: If you are using it for the first time or after multiple uses, it is recommended that you wash it first with hot water or lemonade. It is recommended to use it twice or three times a week. During the first few days of using the tongue scraper may in some cases provoke a feeling of nausea. This feeling will disappear with time, please don't worry. Do not use the tongue scraper too deep into the root of the tongue, to avoid the sensation of vomiting cause by simulation. Kids should use it under parental supervision.
