الحلبة
A bitter seed used as a food and remedy, cited in secondary Prophetic-medicine literature though on a weaker chain than the major hadith.
لَوْ يَعْلَمُ النَّاسُ مَا فِي الْحُلْبَةِ لَاشْتَرَوْهَا وَلَوْ بِوَزْنِهَا ذَهَبًا
“If people knew what benefit is in fenugreek, they would purchase it even at its weight in gold.” (meaning, not a literal translation)
Unlike the honey account, this saying is better attested in general medical practice of the classical era than through a single authenticated prophetic report — it appears in later Tibb al-Nabawi compilations building on the broader tradition rather than in the primary hadith collections themselves. It's included here with its weak grading stated plainly, since fenugreek's use as a tonic in the wider classical literature is well documented regardless of this specific saying's chain.
Later commentators discuss fenugreek as warming and beneficial for digestion and postnatal recovery, consistent with its continued traditional and modern herbal use. In the broader classical medical literature that Ibn al-Qayyim's work draws on, fenugreek was commonly prepared as a soaked seed infusion or cooked into a broth for those regaining strength after fever or prolonged illness, and applied as a poultice for localized swelling.
Modern nutritional research has studied fenugreek seed for effects on blood sugar regulation and lactation support, among other areas. Noted here as separate modern context, not as validation of the classical account or its grading.
