The two correctives are the pomegranate and the luke-warm water...

[4] عَنْهُ عَنْ بَعْضِ أَصْحَابِهِ رَفَعَهُ قَالَ قَالَ أَبُو عَبْدِ اللَّهِ ( عليه السلام ) ثَلَاثٌ لَا يُؤْكَلْنَ وَ هُنَّ يُسْمِنَّ وَ ثَلَاثٌ يُؤْكَلْنَ وَ هُنَّ يَهْزِلْنَ وَ اثْنَانِ يَنْفَعَانِ مِنْ كُلِّ شَيْ‏ءٍ وَ لَا يَضُرَّانِ مِنْ شَيْ‏ءٍ وَ اثْنَانِ يَضُرَّانِ مِنْ كُلِّ شَيْ‏ءٍ وَ لَا يَنْفَعَانِ مِنْ شَيْ‏ءٍ From him, from one of our companions, raising it, said, ‘Abu Abdullah -asws said: ‘Three things which are nor eaten and these fatten, and three are eaten and these slim (the body), and two benefit from every things and do not harm from anything, and two harm from everything and do not benefit from anything.

فَأَمَّا اللَّوَاتِي لَا يُؤْكَلْنَ وَ يُسْمِنَّ اسْتِشْعَارُ الْكَتَّانِ وَ الطِّيبُ وَ النُّورَةُ وَ أَمَّا اللَّوَاتِي يُؤْكَلْنَ وَ يَهْزِلْنَ فَهُوَ اللَّحْمُ الْيَابِسُ وَ الْجُبُنُّ وَ الطَّلْعُ وَ فِي حَدِيثٍ آخَرَ الْجَرَزُ وَ الْكُسْبُ وَ اللَّذَانِ يَنْفَعَانِ مِنْ كُلِّ شَيْ‏ءٍ وَ لَا يَضُرَّانِ مِنْ شَيْ‏ءٍ فَالْمَاءُ الْفَاتِرُ وَ الرُّمَّانُ وَ اللَّذَانِ يَضُرَّانِ مِنْ كُلِّ شَيْ‏ءٍ وَ لَا يَنْفَعَانِ مِنْ شَيْ‏ءٍ فَاللَّحْمُ الْيَابِسُ وَ الْجُبُنُّ So as for those which are not eaten and these fatten are the linen, and the perfume, and the Noura (Lime-wax); and as for those which are eaten and they slim (the body), so these are the dried meat, and the cheese, and the spadix’ – and in another Hadeeth: ‘The Prairie moon (a herb), and oil-cake; and the two which benefit from everything and do not harm from anything the luke-warm water and the pomegranate; and those two which harm from everything and do not benefit from everything, so it is the dried meat, and the cheese’.

قُلْتُ جُعِلْتُ فِدَاكَ ثَمَّ قُلْتَ يَهْزِلْنَ وَ قُلْتَ هَاهُنَا يَضُرَّانِ فَقَالَ أَ مَا عَلِمْتَ أَنَّ الْهُزَالَ مِنَ الْمَضَرَّةِ . I said, ‘May I be sacrificed for you -asws ! Then you -asws said: ‘They slimmen (the body)’, and over here they are both harmful’.
