"Al-'Ajwah is from Paradise and it contains a cure for poison. Truffles are a form of manna, and its liquid is a cure for the eye." (Using translation from Tirmidhī 2066)
قَالَ رَسُولُ اللهِ ﷺ الْكَمْأَةُ مِنَ الْمَنِّ وَمَاؤُهَا شِفَاءٌ لِلْعَيْنِ وَالْعَجْوَةُ مِنَ الْجَنَّةِ وَهِيَ شِفَاءٌ مِنَ السُّمِّ
