Is the Hadith: "If my people knew what was in fenugreek, they would buy it with gold," authentic, and what is the meaning of fenugreek?

The Hadith: "If people knew what was in fenugreek, they would buy it even for its weight in gold," was narrated by Al-Tabarani in Al-Kabeer, and it is weak or fabricated. In its chain of narration is Sulaiman Al-Jana'izi, who was a liar, and Ahmad bin Abdur-Rahman, known as Hajdar, who used to steal Hadith. Therefore, Ibn Al-Jawzi mentioned it in Al-Mawdu'at (Fabricated Hadiths), and Al-Suyuti followed him. Fenugreek is a plant used for treatment.
