Sunan Ibn Majah, Chapter: The Chapters on Medicine

"I brought a son of mine to the Prophet (saw), and I had pressed on an area of his throat due to tonsillitis. He said: 'Why do you poke your children with this pressing?' You should use this aloeswood, for in it there are seven cures. It should be inhaled for pustules in the throat, and given in the side of the mouth for pleurisy." (Another chain) from Umm Qais bint Mihsan, from the Prophet (saw) with similar wording.
