Not only diamonds and gold are expensive. Then what else?
Saffron is a plant belonging to the iris family (Iridaceae). People used it for thousands of years in the kitchen and as a natural remedy. Saffron has many scientifically proved benefits (calming, appetizing, antispasmodic), but also helps with slight depression, irregular menstruation and abdominal issues. Nowadays it is not so commonly used because of it’s high price. Saffron should not be mixed up with safflower, which is much cheaper.
