To sniff the Indian and sea Qust (kind of incense)

Narrated Um Qais bint Mihsan:

I heard the Prophet saying, "Treat with the Indian incense, for it has healing for seven diseases;
it is to be sniffed by one having throat trouble, and to be put into one side of the mouth of one suffering from pleurisy." Once I went to Allah's Apostle with a son of mine who would not eat any food, and the boy passed urine on him whereupon he asked for some water and sprinkled it over the place of urine.

حَدَّثَنَا صَدَقَةُ بْنُ الْفَضْلِ، أَخْبَرَنَا ابْنُ عُيَيْنَةَ، قَالَ سَمِعْتُ الزُّهْرِيَّ، عَنْ عُبَيْدِ اللَّهِ، عَنْ أُمِّ قَيْسٍ بِنْتِ مِحْصَنٍ، قَالَتْ سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ " عَلَيْكُمْ بِهَذَا الْعُودِ الْهِنْدِيِّ، فَإِنَّ فِيهِ سَبْعَةَ أَشْفِيَةٍ. يُسْتَعَطُ بِهِ مِنَ الْعُذْرَةِ، وَيُلَدُّ بِهِ مِنْ ذَاتِ الْجَنْبِ ". وَدَخَلْتُ عَلَى النَّبِيِّ ﷺ بِابْنٍ لِي لَمْ يَأْكُلِ الطَّعَامَ فَبَالَ عَلَيْهِ، فَدَعَا بِمَاءٍ فَرَشَّ عَلَيْهِ.
