Sahih Bukhari Volume 7, Book 71, Hadith Number 616.

Narrated By Um Oais: That she took to Allah’s Apostle one of her sons whose palate and tonsils she had pressed to treat a throat trouble. The Prophet said, “Be afraid of Allah! Why do you pain your children by having their tonsils pressed like that? Use the Ud Al-Hindi (a certain Indian incense) for it cures seven diseases, one of which is pleurisy.”
