Azafrán, the Spanish word for saffron, is used for cooking, improving mood, dyeing textiles, and a growing list of health applications. It comes from the dried stigmas of the Crocus sativus flower and is the most expensive spice in the world by weight, largely because producing a single kilogram requires hand-picking over 150,000 flowers. That labor intensity is part of what makes azafrán so prized, but its value also comes from a remarkably wide range of uses that stretch back thousands of years.
Cooking With Azafrán
The flavor of azafrán is floral and slightly bitter, with a honey-like warmth that no other spice replicates. A few threads are enough to color an entire pot of rice a deep golden yellow and infuse it with that signature aroma. Only a tiny amount is needed per dish, which is why even a small container lasts months in most kitchens.
Spanish paella is probably the most iconic azafrán dish globally. The spice gives the rice its distinctive color and ties together the flavors of seafood, chicken, or vegetables. In Indian cooking, azafrán is essential to biryani, where it’s steeped in warm milk and drizzled over layers of basmati rice, and to kheer, a creamy rice pudding. Persian cuisine uses it to marinate chicken and lamb kebabs before grilling, and both Iranian and Indian tea traditions include saffron-steeped versions as a warming, aromatic drink.
Mood and Mental Health
Azafrán has some of the strongest evidence of any botanical supplement for improving low mood. A 2025 randomized trial published in The Journal of Nutrition gave 202 adults with depressive symptoms either 28 mg of saffron extract daily or a placebo. The saffron group saw significantly greater improvements in depression scores, with 72.3% achieving a clinically meaningful reduction in symptoms compared to 54.3% in the placebo group.
The same trial found that participants with notable sleep problems experienced improved sleep quality on saffron. The effect sizes in these studies are considered small to moderate, so azafrán is not a replacement for standard treatment in severe depression, but the results are consistent enough across multiple trials that it’s gaining recognition as a supplemental option for mild to moderate symptoms.
Eye Health and Vision
One of the more surprising uses of azafrán is for age-related macular degeneration (AMD), the leading cause of vision loss in older adults. Multiple clinical studies have found that daily supplementation with 20 to 50 mg of saffron for three to twelve months improved visual sharpness, contrast sensitivity, and retinal function in people with both wet and dry forms of AMD. These benefits held regardless of a person’s genetic risk factors for the disease, suggesting azafrán’s protective compounds work through broadly applicable pathways in the retina.
PMS Symptom Relief
Several clinical trials have tested azafrán for premenstrual syndrome, and the results are consistently positive. Saffron supplementation significantly reduced PMS symptoms including abdominal bloating, depression, and mood swings across multiple studies. It also improved scores on standardized depression rating scales during the premenstrual phase. The mechanism likely involves the same mood-regulating properties that make it useful for general depression, applied to the hormonal mood shifts of the menstrual cycle.
Weight Management
Azafrán appears to help with weight control through two pathways: it reduces how much fat the body absorbs from food by interfering with a digestive enzyme, and it increases feelings of fullness by influencing brain chemicals tied to satiety. In a double-blinded trial with obese adolescents, saffron supplementation significantly reduced body weight, BMI, and waist circumference compared to a placebo. The effect was smaller than what the prescription medication metformin achieved in the same study, but it was still meaningful. Reduced snacking behavior is one of the more practical effects people report.
Dyeing, Cosmetics, and Fragrance
Long before azafrán became a culinary staple, it was a dye. The pigment responsible for saffron’s golden color has been used to dye textiles for millennia. Ancient Greeks and Romans colored their clothing with it and added it to bathwater. Buddhist and Hindu monks in India, Tibet, and China traditionally used saffron to dye their robes. In the Ottoman Empire, it was considered the premier natural dye and was also used to make ink. Persian carpets and rugs owe some of their famous golden tones to saffron dye as well.
The dye works on both natural and synthetic fibers and produces shades ranging from bright yellow to brownish gold depending on the chemical used to fix the color. Modern research has shown that microwave-assisted extraction of saffron dye onto cotton fabric not only improves color strength but also gives the fabric antimicrobial properties.
In cosmetics, azafrán has a long history as a coloring agent in products like lip rouge. It also appears in perfumery, where its warm, slightly sweet scent serves as a middle note in complex fragrance blends.
How Much Is Safe to Use
For cooking, the amounts used are tiny and perfectly safe. For supplemental health purposes, clinical studies have tested doses ranging from 20 to 400 mg per day, with 20 to 30 mg daily being the most common dose studied for mood support. Dosages up to 1.5 grams per day are considered safe. Toxic effects begin at around 5 grams, and doses between 10 and 20 grams can be fatal. To put that in perspective, 5 grams of saffron is an enormous quantity that you would never encounter in normal cooking or supplementation. A typical pinch for a pot of paella is well under half a gram.
