I don’t recommend following those instructions about the Taveez. Sometimes doing those things have worse long term effects.
I recommend the following:
1- Have her wear the Herz of Imam Jawad (a) and Imam Redha (a).
2- Slaughter a sheep in your house if you can. If not then elsewhere and have it be given to the poor with the intention of having your wife cured from this condition.
3- Search for any strange objects in the house and throw them in a river or lake.
4- Bring a pair of pigeons to your house if possible.
5- Write Ayatul Kursi and hang it on the wall of each room.
6- Read this Du’a daily:

7- Recite Hadith al-Kisaa’ on seven dates and let her eat a date each day for seven days.
8- Read this Du’a then when finished reading it ask Allah to cure her:
اللَّهُمَّ رَبَّ السَّمَاوَاتِ السَّبْعِ وَ مَا بَيْنَهُنَّ وَ رَبَّ الْعَرْشِ الْعَظِيمِ، وَ رَبَّ جَبْرَئِيلَ وَ مِيكَائِيلَ وَ إِسْرَافِيلَ، وَ رَبَّ الْقُرْآنِ الْعَظِيمِ، وَ رَبَّ مُحَمَّدٍ خَاتَمِ النَّبِيِّينَ ، إِنِّي أَسْأَلُكَ بِالَّذِي تَقُومُ بِهِ السَّمَاءَ، وَ بِهِ تَقُومُ الْأَرْضَ، وَ بِهِ تُفَرِّقُ بَيْنَ الْجَمْعِ، وَ بِهِ تَجْمَعُ بَيْنَ الْمُتَفَرِّقِ، وَ بِهِ تَرْزُقُ الْأَحْيَاءَ، وَ بِهِ أَحْصَيْتَ عَدَدَ الرِّمَالِ وَ وَزْنَ الْجِبَالِ وَ كَيْلَ الْبُحُورِ، ثُمَّ تُصَلِّي عَلَى مُحَمَّدٍ وَ آلِ مُحَمَّدٍ
May Allah grant her a speedy recovery.
