Saffron

Saffron is a plant. The dried stigmas (thread-like parts of the flower) are used to make saffron spice. Saffron is largely cultivated and harvested by hand. Due to the amount of labor involved in harvesting, saffron is considered one of the world's most expensive spices.

People use saffron most commonly for depression, anxiety, Alzheimer disease, menstrual cramps (dysmenorrhea), and premenstrual syndrome (PMS). Saffron is also used for many other conditions, but there is no good scientific evidence to support many of these uses.
