The Source of Traditions on Imam al-Riḍā (Vol 2) · Hadith 74 (#Ḥadīth #74)

74 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُعَلَيْهِ وَآلِهِ: اِدَّهنُوا بِالبَنَفسَجِ فَإِنَّهُ بارِدٌ في الصَّيفِ وَحارٌّ في الشِّتاءِ.

31-74 According to the same documentation, God’s Prophet (S) said, “Use viola to smell good since it feels cool in the summer and warm in the winter.”
