Kesar: What Is It and Why the Confusion?
Kesar is simply the Hindi and Urdu name for the world's most expensive spice, saffron. Derived from the stigma of the Crocus sativus flower, its high price is a result of the labor-intensive hand-harvesting process. A vibrant red spice prized for its potent flavor, color, and aroma, it has a rich history in cooking, traditional medicine, and cosmetics across different cultures. The confusion over its health impact stems from the vast difference between using it as a subtle culinary ingredient and consuming it in high, concentrated doses for medicinal purposes.
The Good: Powerful Health Benefits of Kesar
At a low dosage typical for culinary use, kesar is generally safe and offers a range of potential health benefits largely attributed to its rich content of antioxidants, including crocin, crocetin, and safranal.
Mood Enhancement and Anti-Depressant Effects
Several clinical studies and reviews have shown saffron's efficacy in improving mood and treating symptoms of mild to moderate depression. Its active compounds work by affecting neurotransmitters like serotonin and dopamine in the brain, helping to regulate mood and reduce stress. Some studies even suggest it can be as effective as some conventional antidepressants, but with fewer side effects.
Potential for Weight Management
Research indicates that saffron may help reduce appetite and aid in weight loss. By interacting with satiety hormones, it can make individuals feel fuller, potentially curbing snacking and emotional eating. A 2023 study found that saffron supplementation significantly reduced BMI and waist circumference over a 12-week period.
Support for Eye Health
The antioxidants in kesar, particularly crocetin and crocin, are known to support retinal health and may help prevent age-related macular degeneration (AMD), a leading cause of vision loss in older adults. Regular consumption has shown promise in improving eyesight and contrast sensitivity.
Alleviates PMS Symptoms
For women, a daily intake of saffron may help reduce the physical and emotional symptoms of premenstrual syndrome (PMS), such as mood swings, irritability, and cramping. Some studies have found a significant reduction in symptoms for women taking saffron supplements compared to a placebo.
Protects Against Oxidative Stress
Kesar's high concentration of antioxidants protects the body's cells from oxidative stress and free radicals, which are linked to chronic diseases like cancer and heart disease. Research suggests saffron and its compounds can suppress tumor growth and protect against cellular damage.
The Bad: Risks and Dangers of Excessive Kesar
The primary danger associated with kesar comes from consuming it in large, unregulated doses, such as those found in some high-potency supplements. This is where the line between 'good' and 'bad' becomes critical.
High Doses Can Be Toxic and Fatal
While a pinch of saffron in your paella is harmless, excessive amounts are toxic. High doses of 5 grams or more can cause poisoning, and doses between 12 and 20 grams can be lethal. The side effects of saffron poisoning can include yellowed skin, vomiting, bloody diarrhea, and even bleeding from the nose, lips, and eyelids.
Significant Risk During Pregnancy
Pregnant women should avoid consuming kesar in amounts larger than those typically used in cooking. High doses can cause uterine contractions, which can lead to miscarriage. While some traditions claim saffron brightens a baby's complexion, this is a myth with no scientific basis. It's best to consult a healthcare professional before adding saffron to a pregnancy diet, especially in the first trimester.
Adverse Medication Interactions
Kesar can interact with certain medications, amplifying their effects or causing complications. It may lower blood pressure, which could cause dangerously low blood pressure when taken with antihypertensive drugs. It can also lower blood sugar levels and may interfere with diabetes medications. Anyone on medication should consult a doctor before taking saffron supplements.
Other Potential Side Effects
Even at medicinal, non-toxic doses, some individuals may experience side effects such as drowsiness, dizziness, dry mouth, changes in appetite, nausea, and headache. These effects are more common with supplemental doses than with culinary amounts.
Kesar Consumption: Safe vs. Unsafe Quantities
This table highlights the critical difference between using kesar as a spice and consuming it in potentially harmful quantities.
| Feature | Safe (Culinary) Consumption | Unsafe (High-Dose/Toxic) Consumption |
|---|---|---|
| Dosage | A few threads or a pinch per serving (<1.5g per day) | 5g or more can be toxic; 12-20g can be lethal |
| Context | Used as a spice in food (paella, risotto, milk) to add color and flavor | Often involves supplements or teas in medicinal amounts |
| Benefits | Mood enhancement, antioxidant protection, digestion aid | May lead to severe side effects and toxicity, overshadowing benefits |
| Risks | Very low risk for most people, but potential for allergic reactions | Severe poisoning, allergic reactions, dangerous for pregnant women, and interacts with medications |
| Safety | Considered possibly safe for most individuals, follow general usage guidelines | High risk and potentially life-threatening |
Conclusion
In summary, the question of whether kesar is good or bad for you comes down to moderation and informed decision-making. When used in small, culinary amounts, its antioxidant and mood-enhancing properties provide numerous health benefits with minimal risk. However, consuming large, unregulated doses of saffron, particularly through concentrated supplements, poses serious health risks, including potential toxicity and dangerous interactions, especially for pregnant women and those with pre-existing conditions. As with any potent natural substance, caution, awareness of dosage, and consultation with a healthcare professional are essential to reap the rewards while avoiding the dangers.

How to Safely Enjoy Kesar
To safely incorporate kesar into your diet, consider these tips:
- Steep, Don't Boil: To maximize flavor and prevent bitterness, steep a few saffron threads in warm (not boiling) water or milk for 10–15 minutes before adding to your dish.
- Buy Threads, Not Powder: Saffron powder is more susceptible to adulteration with cheaper substitutes like turmeric. Purchasing threads from a reputable supplier ensures purity.
- Start Small: Just a pinch is often enough for most recipes. A little goes a long way with this potent spice.
- Check with a Doctor: Always consult your physician before starting any new supplement regimen, especially if you have an underlying health condition, are pregnant, or are taking medication.
By following these guidelines, you can enjoy the vibrant flavor and potential benefits of this precious spice without putting your health at risk.
