"I went to Allah's Messenger (ﷺ) along with a a son of mine whose palate and tonsils I had pressed with my finger as a treatment for a (throat and tonsil) disease. The Prophet (ﷺ) said, "Why do you pain your children by pressing their throats! Use Ud Al-Hindi (certain Indian incense) for it cures seven diseases, one of which is pleurisy. It is used as a snuff for treating throat and tonsil disease and it is inserted into one side of the mouth of one suffering from pleurisy.""
