Fenugreek
Fenugreek (Trigonella foenum-graecum) is an annual herb used as a spice, mainly in Persian, Indian and Thai cooking. It grows wild from the eastern Mediterranean to China, but is cultivated worldwide. In folk medicine, fenugreek is used internally for underweight, and externally for various inflammations. Results from clinical trials suggest that fenugreek extract supplements testosterone levels in men and also lower blood sugar.
Fenugreek's aroma is said to be somewhat nutty and in its sweetest form can be reminiscent of maple syrup, while as a spice it can sometimes turn into celery.
