Saffron is a very expensive spice, used to flavor and color food. The spice is actually the dried stigma (tiny threadlike strands) of the Crocus Sativus Linneaus, a member of the iris family. Each stigma is very small, and tens of thousands of individual strands go into a single ounce of the spice; since the stigmas are hand-plucked from the individual flowers, saffron's high cost becomes more understandable. It is thought that saffron is the most expensive spice in the world.
saffron gives saffron its unmistakable taste and fragrance. Research shows that it might help improve your disposition, memory, and learning capacity, just as ensure your synapses against oxidative pressure
