Saffron is the most expensive spice in the world — with 1 pound (450 grams) costing between $500 and $5,000.

The reason for its high price is its labor-intensive harvesting method, which makes its production costly.

Saffron is harvested by hand from the Crocus sativus flower, commonly known as the saffron crocus. The term “saffron” applies to the flower’s thread-like structures called stigma.

While saffron’s origin is still debated, it most likely originated in Iran. There, it was revered for its medicinal properties. People would eat saffron to enhance libido, boost mood, and improve memory (1).

Here are 11 impressive health benefits of saffron.

Saffron contains an impressive variety of plant compounds. These act as antioxidants — molecules that protect your cells against free radicals and oxidative stress.

Notable saffron antioxidants include (2):

  • crocin
  • crocetin
  • safranal
  • kaempferol

Crocin and crocetin are carotenoid pigments responsible for saffron’s red color. Both compounds may (2, 3):

  • have antidepressant properties
  • protect brain cells against progressive damage
  • improve inflammation
  • reduce appetite
  • aid weight loss

Safranal gives saffron its distinct taste and aroma. Research shows that it may help improve your mood, memory, and learning ability, as well as protect your brain cells against oxidative stress (4).

Lastly, kaempferol is found in saffron flower petals. This compound has been linked to health benefits, such as reduced inflammation, anticancer properties, and antidepressant activity (2, 5).

Summary

Saffron is rich in plant compounds that act as antioxidants, such as crocin, crocetin, safranal, and kaempferol. Antioxidants help protect your cells against oxidative stress.

Saffron is nicknamed the sunshine spice. This is not just due to its distinct color but also because it may help brighten your mood.

In a review of five studies, saffron supplements were significantly more effective than placebos at treating symptoms of mild-to-moderate depression (6).

Other studies found that taking 30 mg of saffron daily was just as effective as Fluoxetine, Imipramine, and Citalopram — conventional treatments for depression. Additionally, fewer people experienced side effects from saffron than from other treatments (7, 8, 9).

Both the saffron petals and thread-like stigma appear to be effective against mild-to-moderate depression (1, 10).

While these findings are promising, longer human studies with more participants are needed before experts can recommend saffron as a treatment for depression.

Summary

Saffron may help treat symptoms of mild-to-moderate depression, but more studies are needed before definite recommendations can be made.

Saffron is high in antioxidants, which help neutralize harmful free radicals. Free radical damage has been linked to chronic diseases, such as cancer (11).

In test-tube studies, saffron and its compounds have been shown to selectively kill colon cancer cells or suppress their growth, while leaving healthy cells unharmed (12).

This effect also applies to skin, bone marrow, prostate, lung, breast, cervix, and several other cancer cells (13).

Test-tube studies have also found that crocin — the main antioxidant in saffron — may make cancer cells more sensitive to chemotherapy drugs (14).

While these findings from test-tube studies are promising, the anticancer effects of saffron are poorly studied in humans, and more research is needed.

Summary

Saffron is high in antioxidants, which may help kill cancer cells while leaving healthy cells unharmed. However, more human research is needed.

Premenstrual syndrome (PMS) is a term that describes physical, emotional, and psychological symptoms occurring before the start of a menstrual period.

Studies show that saffron may help treat PMS symptoms.

In women ages 20–45, taking 30 mg of saffron daily was more effective than a placebo at treating PMS symptoms, such as irritability, headaches, cravings, and pain (15).

Another study found that simply smelling saffron for 20 minutes helped reduce PMS symptoms like anxiety and lowered levels of the stress hormone cortisol (16).

Summary

Both eating and smelling saffron appears to help treat PMS symptoms, such as irritability, headaches, cravings, pain, and anxiety.

Aphrodisiacs are foods or supplements that help boost your libido. Studies have shown that saffron may have aphrodisiac properties — especially in people taking antidepressants.

For instance, taking 30 mg of saffron daily over 4 weeks significantly improved erectile function over a placebo in men with antidepressant-related erectile dysfunction (17).

Additionally, an analysis of six studies showed that taking saffron significantly improved erectile function, libido, and overall satisfaction but not semen characteristics (18).

In women with low sexual desire due to taking antidepressants, 30 mg of saffron daily over 4 weeks reduced sex-related pain and increased sexual desire and lubrication, compared with a placebo (19).

Summary

Saffron may have aphrodisiac properties for both men and women and may especially help those taking antidepressants.

Snacking is a common habit that may cause you to gain weight. According to research, saffron may help prevent snacking by curbing your appetite.

In one 8-week study, women taking saffron supplements felt significantly more full, snacked less frequently, and lost significantly more weight than women in the placebo group (20).

In another 8-week study, taking a saffron extract supplement helped significantly reduce appetite, body mass index, waist circumference, and total fat mass (3).

However, scientists are unsure how saffron curbs appetite and aids weight loss. One theory is that saffron elevates your mood, which in turn reduces your desire to snack (20).

Summary

Saffron has been shown to reduce snacking and curb your appetite. In turn, these behaviors may help you lose weight.

Saffron has been linked to other health benefits that have not yet been extensively studied:

  1. May reduce heart disease risk factors. Animal and test-tube studies indicate that saffron’s antioxidant properties may lower blood cholesterol and prevent blood vessels and arteries from clogging (21, 22, 23).
  2. May lower blood sugar levels. Saffron may lower blood sugar levels and raise insulin sensitivity, as seen in test-tube studies and mice with diabetes (24, 25).
  3. May improve eyesight in adults with age-related macular degeneration (AMD). Saffron appears to improve eyesight in adults with AMD and protect against free radical damage, which is linked to AMD (26, 27, 28).
  4. May improve memory in adults with Alzheimer’s disease. Saffron’s antioxidant properties may improve cognition in adults with Alzheimer’s disease (29).
Summary

Saffron has been linked to several other potential health benefits, such as improved heart disease risk, blood sugar levels, eyesight, and memory. However, more studies are needed to draw stronger conclusions.

In small doses, saffron has a subtle taste and aroma and pairs well with savory dishes, such as paella, risottos, and other rice dishes.

The best way to draw out saffron’s unique flavor is to soak the threads in hot — but not boiling — water. Add the threads and the liquid to your recipe to achieve a deeper, richer flavor.

Saffron is readily available at most specialty markets and can be purchased as threads or in powdered form. It’s best to buy the threads, if possible, since they can be used in many different ways and are less likely to be adulterated.

Though saffron is the most expensive spice in the world, a small amount goes a long way. You often won’t need more than a pinch in your recipes. In fact, using too much saffron can give your recipes an overpowering medicinal taste.

In addition, saffron is available in supplement form.

Summary

Saffron has a subtle taste and aroma, which makes it easy to add to your diet. It pairs well with savory dishes and should be soaked in hot water to give a deeper flavor. Alternatively, you can purchase saffron in supplement form to reap its benefits.

Saffron is generally safe with little to no side effects.

In standard cooking amounts, saffron does not appear to cause adverse effects in humans.

As a dietary supplement, people can safely take up to 1.5 grams of saffron per day. However, only 30 mg of saffron per day have been shown to be enough to reap its health benefits (7, 17, 30).

On the other hand, high doses of 5 grams or more can have toxic effects. Pregnant people should avoid high doses, which may cause miscarriage (31, 32, 33).

As with any supplement, speak with a healthcare professional before taking saffron in supplement form.

Another issue with saffron — especially saffron powder — is that it may be adulterated (mixed) with other ingredients, such as beet, red-dyed silk fibers, turmeric, and paprika.

Adulteration cuts cost for manufacturers since real saffron is expensive to harvest (33).

It’s important to purchase saffron from a reputable brand to ensure you get an authentic product. If the saffron appears too cheap, its best to avoid it.

Summary

In standard doses, saffron is generally safe with little to no side effects. Make sure to purchase saffron from a reputable brand or store to avoid an adulterated product.

Saffron is a powerful spice high in antioxidants.

It has been linked to health benefits, such as improved mood, libido, and sexual function, as well as reduced PMS symptoms and enhanced weight loss.

Best of all, it’s generally safe for most people and easy to add to your diet. Try incorporating saffron into your favorite dishes to take advantage of its potential health benefits or purchase a supplement online.
