Health Benefits of Saffron: Backed by Science

Saffron is not just a spice with a tantalizing taste — it also has many health benefits. Studies have shown that it can improve your mood, protect your brain, and even help your heart. Our knowledge of saffron is a fascinating combination of ancient wisdom and cutting-edge science, both of which reveal the extraordinary potential of this vibrant and coveted spice.

What is saffron?

Saffron is a vibrant and coveted spice that's derived from the bright red stigma of Crocus sativus L. Commonly known as saffron crocus or autumn crocus, this extraordinary plant belongs to the iris family.

Crocus sativus stigma not only produces the delicious saffron spice but also collects pollen for the flower. The saffron flower is stunning, with vibrant purple petals, prominent yellow stamen, and a bright red stigma at the flower's center.

Why is saffron so expensive?

Saffron crocus is a perennial bulb plant that blossoms during autumn. Astonishingly, it takes approximately 1,000 of these blossoms to produce 5 grams of dried saffron — a testament to the labor-intensive process behind this spice.

Estimates suggest that a pound of saffron requires collecting a staggering 225,000 stigmas from 75,000 blossoms. Given the significant dedication necessary to produce, it's no wonder that saffron is one of the world's most precious and expensive spices.

Saffron's rich history

Saffron's history is as colorful as its petals, spanning back 3,000 to 4,000 years through the civilizations of Greece, Rome, Egypt, and Persia. Avicenna, the Persian physician from the 10th century, used saffron to treat inflammation and respiratory ailments and utilized it as an aphrodisiac.

Health benefits from saffron

Although saffron has been used for over 4,000 years, modern science is only beginning to comprehend its therapeutic benefits fully.

Saffron is a strong antioxidant

Saffron is an excellent source of natural antioxidants that help protect our cells from damage. Let's explore the key antioxidant compounds in saffron:

• Crocin and crocetin. Crocin and crocetin are two saffron components that act as antioxidants by preventing the formation of harmful molecules called free radicals. They also enhance the activity of important enzymes that help keep our bodies healthy.
• Safranal. Safranal contributes to saffron's antioxidant abilities by combating oxidative damage — especially in conditions like type 2 diabetes, neurodegenerative diseases, and cardiovascular protection.
• Carotenoids, phenolic compounds, and flavonoids. These compounds act as antioxidants by neutralizing harmful substances and reducing free radicals, strengthening saffron's antioxidant properties.

Scientists have confirmed saffron's remarkable antioxidant properties, making it a valuable addition to our diet.

Improve inflammation with saffron

Saffron is a natural ally against inflammatory conditions. Crocetin and crocin, present in saffron, exhibit potent anti-inflammatory properties. They achieve this by inhibiting cyclooxygenase (COX) 1 and 2 enzymes, effectively blocking the production of prostaglandin E2 (PGE2), a type of prostaglandin associated with inflammation in the body.

This anti-inflammatory mechanism is similar to nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, which also reduce inflammation through COX inhibition.

While crocetin and crocin are primary contributors to saffron's anti-inflammatory effects, saffron's rich composition of antioxidants, including safranal and other bioactive compounds, may also contribute to its anti-inflammatory properties by neutralizing harmful molecules, reducing oxidative stress, and modulating various signaling pathways involved in inflammation.

Boost your mood with saffron

Human trials have shown that saffron can significantly reduce symptoms of mild to moderate depression. Patients included in the studies took 30–80 mg of saffron stigma extract daily for 4–12 weeks.

Here's the exciting part — not only did saffron improve mood and depression symptoms, but it was as effective as antidepressant medications. While the results are promising, researchers are eager for more robust trials in the future.

Research also revealed that saffron's bioactive compounds, including safranal, crocins, and crocetin, can activate the brain's serotonin, norepinephrine, and dopamine systems to boost your mood. So, if your mood needs a pick-me-up, consider adding some saffron to your routine.

Saffron's role in the fight against Alzheimer's

In the fight against Alzheimer's disease, saffron may hold a golden key.

Alzheimer's disease is linked to sticky protein clumps in the brain, which cause memory loss and damage. Crocin, a saffron compound, can help reduce these clumps.

Studies in mice show that crocin and crocetin increase brain-protective substances like glutathione peroxidase, superoxide dismutase, and the brain-function enhancer choline acetyltransferase. While crocin and crocetin increase the brain-protective substances, they also lower harmful cell-damaging molecules like the sticky protein clumps associated with Alzheimer’s disease.

This brain-protecting magic happens in the cerebral cortex (responsible for thinking) and the hypothalamus (which controls vital body functions).

A recent study showed that high doses of saffron (15 mg/kg twice daily for 22 weeks) are as effective as donepezil, a standard Alzheimer's medication, in treating mild to moderate Alzheimer's disease. However, the patients who received saffron reported more cases of vomiting than the donepezil group. Despite this, saffron has been found to improve cognitive functions in Alzheimer's patients.

Thus, saffron may assist us in the battle against Alzheimer's disease by helping to maintain a healthy and sharp brain.

Six additional health benefits of saffron

Saffron, known as the golden spice, has many potential health benefits and requires much more research to confirm its effectiveness for various ailments. Here are six additional conditions that saffron is currently being researched for:

• Parkinson's disease. In animal studies, compounds found in saffron, such as crocetin and crocin, have demonstrated neuroprotective properties. This may offer hope for those with Parkinson's disease, as these compounds may help shield brain cells from harm.
• Type 2 diabetes. Saffron has the potential to benefit individuals with type 2 diabetes by enhancing insulin sensitivity and regulating blood sugar levels.
• High blood pressure. Studies indicate that extracts of saffron can lower blood pressure by relaxing blood vessels.
• Atherosclerosis. Saffron may reduce the progression of atherosclerosis by minimizing oxidative stress and inflammation caused by plaque buildup in the arteries.
• High lipid levels. Preliminary research suggests that saffron may aid in managing lipid levels by reducing "bad" LDL cholesterol and triglycerides while increasing "good" HDL cholesterol.

To add to saffron's potential health benefits, ongoing research is exploring its potential in addressing age-related illnesses like eye degeneration and muscle weakness. Although saffron's impact on health is yet to be fully explored, it has shown potential in promoting heart and brain well-being, a source of excitement in natural remedies.

Safety of saffron

Research involving people has revealed that consuming less than 400 mg of saffron daily for short periods, typically 7 to 30 days, doesn't result in any significant health issues. It is crucial to keep certain factors in mind:

• Consult a healthcare provider. If you have kidney problems or tend to bleed easily, it's advisable to consult a healthcare provider before including saffron in your diet.
• Pregnancy precaution. Pregnant individuals should avoid saffron entirely, as it may pose risks during pregnancy.
• Mind your dosage. Excessive saffron intake can be harmful. Consuming over 5 grams of saffron in a day is considered toxic. Also, exceeding 10 grams daily can lead to bleeding in the urinary and digestive systems or uterine stimulation that may result in an abortion. And ingesting more than 20 grams of saffron daily can be life-threatening.
• Potential allergic reactions. Some individuals may be allergic to saffron, leading to allergic reactions such as hives, swelling, or difficulty breathing. If you experience any signs of an allergic reaction, discontinue saffron use immediately and seek medical attention.
• Side effects. Large doses of saffron may have side effects, including nausea and vomiting. Be cautious not to exceed recommended doses.
• Commercial saffron products. Saffron products available commercially often recommend daily doses ranging from 30 to 180 mg, which are generally safe for most individuals.

As with most herbal medicine applications, further research is needed to ensure saffron's long-term safety and understand how it affects individuals based on age, gender, and overall health.
