Toxic in large doses

Dried red stigmas from a purple crocus flower, used to flavor and color food and studied for mood.

Did you know? Each crocus flower has only three red threads, so it takes thousands of flowers to make a single ounce of spice.

What it may help, and how strong the proof is

  • Low mood. Several small trials in mild to moderate depression found it beat placebo over several weeks. The studies are small and mostly from Iran.
    Early proof
  • Women's health. A small trial suggested it eased premenstrual symptoms. Larger trials are lacking.

The honest take

Saffron is the costliest spice, and adulterated saffron is common. Its mood studies are small and short, so they are promising but not proven. Its best use is as a flavor and color, and large amounts are dangerous.
