Yes, Lybrate-user you can use this local application but at fact these kind of local application will help only to restrict its growth and it will act as a palliative treatment, if you really want to get rid of it you need to take some medication but as well as with that proper diet and some hygiene facts needs to follow, like stop synthetic sour things in food, consume maximum water at least 45 ml×body weight per day, use boiling water for cloth washing, etc for more details you can contact me.
Hope it will help you,
take care.
