Cumin (Cuminum cyminum L.) is a very common spice and found in many kitchens.
The dried, ripe fruit ("seed") is the part used both as a spice and medicinally. Cumin is often found in herbal preparations, or used for its pleasant aroma in other preparations.
Like most seeds, it is the various oils and fatty acids that give cumin its particular activity. Cumin oil has been reported to have some antibacterial properties as well as larvicidal activity.
