Traditionally used as digestive tonic, demulcent, expectorant. „The characteristic foenugreek smell is ascribed to 3-hydroxy-4,5-dimethyl-2[5H]-furanone (sotolon); the bitter taste to the furostanol glycosides.“ [MPW]
Fenugreek is the source of the sotolone present in curry powder. „Furthermore, it is interesting to note that sotolone seems to be relatively stable in the seed, since the sample from Egypt (25mg/kg) was already seven years old.“ [Blank, I.; Schieberle, P.; Grosch, W.
