The correct understanding of the verse regarding honey being a cure is that honey becomes a cure to the sicknesses which are compatible for it. Therefore, honey could not be beneficial for every sickness.
“Ash-Shaykh Bin Baaz rahimahullah was asked the following question about honey:
هناك بعض الأمراض سماحة الشيخ لا تتفق مع العسل، توجيهكم في هذا لو تكرمتم؟
الشيخ: كل دواء يعالج بما يناسبه، يقول النبي ﷺ في الحديث الصحيح: ما أنزل الله داء إلا أنزل له شفاء
The questioner mentions to the Shaykh there are certain illnesses that aren’t compatible with honey and that there are negative reactions when combining them.
Therefore, the Shaykh rahimahullah mentions each sickness is to be treated accordingly to what suitable for it.” End benefit. [Reference]
A Side Benefit:
Some mention that from what lead to the condition of Shaykh Muqbil rahimahullah worsening before his death was someone advising him to intake honey for his sickness which eventually made his medical condition worse. And Allaah knows best.
