 The seeds of yeheb are rich in sodium, potassium and phosphorus; thus they contain a small amount of calcium and magnesium.Both varieties contain a lot of amino acids; yeheb seeds have a high content of the essential amino acids lysine and arginine, but are deficient in tryptophan and isoleucine.Phytohaemagglutinin, a toxic lectin often present in leguminous, is absent in Yeheb seeds; this is an additional nutritional advantage.
