مُحَمَّدُ بْنُ يَحْيَى عَنْ عَبْدِ اللَّهِ بْنِ جَعْفَرٍ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ أَبِي الْحَسَنِ الرِّضَا ( عليه السلام ) أَنَّهُ قَالَ أَطْعِمُوا مَرْضَاكُمُ السِّلْقَ يَعْنِي وَرَقَهُ فَإِنَّ فِيهِ شِفَاءً وَ لَا دَاءَ مَعَهُ وَ لَا غَائِلَةَ لَهُ وَ يُهْدِئُ نَوْمَ الْمَرِيضِ وَ اجْتَنِبُوا أَصْلَهُ فَإِنَّهُ يُهَيِّجُ السَّوْدَاءَ .
4. Muhammad ibn Yahya has narrated from ‘Abd Allah ibn Ja‘far from Muhammad ibn ‘Isa who has said the following: “Abu al-Hassan, al-Rida’ , has said, ‘Feed your patients beets, the leaves, because there is cure in it without illness or shock and it makes sleep of a patient more relaxing; but abstain from its roots because it stirs up al-Sawada ’ (a certain illness).”’
