Saffron contains many vitamins, minerals and antioxidants. The spice also contains manganese, iron, magnesium, phosphorus and copper, and is rich in vitamin C, and B6. These vitamins and minerals, combined with safranal, crocin and picrocrocine, provide the many positive effects that saffron has on our bodies.
Caution: do not use more than 1.5 grams per day of saffron; about two tablespoons. The use of more than 5 grams of saffron suddenly can have harmful effects and is strongly discouraged. The recommended daily minimum amount is 50 milligrams.
One hectare of saffron flowers yields 4 to 4.5 pounds of saffron, for one kilogram of saffron about 150,000 flowers should be harvested. Which account for approximately 450,000 saffron threads. One gram (about 1 heaping tablespoon) equals 450 to 465 threads and a pinch, which fits between thumb and forefinger, contains an average of 10 to 15 whole threads, corresponding to 30 to 50 milligrams.
