Mishkat al-Masabih 4524
Umm Qais reported God's messenger as saying:
“Why do you compress the uvula in this way? Use this Indian aloes wood, for it contains seven types of remedy, among them being a remedy for pleurisy. It is applied through the nose for a swelling of the uvula and poured into the side of the mouth for pleurisy.” 

(Bukhari and Muslim )
وَعَن أُمِّ قَيْسٍ قَالَتْ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «على مَ تَدْغَرْنَ أَوْلَادَكُنَّ بِهَذَا الْعِلَاقِ؟ عَلَيْكُنَّ بِهَذَا الْعُودِ الْهِنْدِيِّ فَإِنَّ فِيهِ سَبْعَةَ أَشْفِيَةٍ مِنْهَا ذَاتُ الْجَنْبِ يُسْعَطُ مِنَ الْعُذْرَةِ وَيُلَدُّ مِنْ ذَاتِ الْجنب»
