Quick answer: Saffron has decent evidence for PMS — mood swings, irritability and tension before a period. Evidence for period cramps is limited and mostly comes from herbal blends. There is no good evidence that saffron fixes irregular periods. The dose studied for PMS was 30 mg a day (about 15 threads), split into two doses.
Medical note: This article is for general information, not medical advice. If you are pregnant, could be pregnant, are managing a condition or take regular medication, check with your doctor before using saffron beyond cooking amounts.
Saffron for PMS
In a 2008 randomised trial published in BJOG, women who took 15 mg of saffron twice a day for two menstrual cycles had a significantly larger drop in PMS symptoms than those on placebo. Mood-related symptoms improved most, which fits saffron's wider research on mood and anxiety.
Saffron for period cramps
Period pain (dysmenorrhoea) has been studied mainly with a herbal mixture of saffron, celery seed and anise, which reduced pain in an Iranian trial. That makes it hard to credit saffron alone. A warm cup of kesar milk or saffron tea can still be soothing, but it should not replace pain relief your doctor recommends.
Saffron for irregular periods
Saffron is traditionally said to "bring on" periods, but there is no good evidence it regulates cycles. Irregular periods often have causes worth checking — thyroid problems, PCOS, stress or pregnancy. Never use saffron to bring on a late period if you could be pregnant: large amounts can stimulate the uterus.
Heavy periods
There is no evidence saffron reduces heavy bleeding. If you have heavy periods or a bleeding disorder, keep to cooking amounts and talk to your doctor, especially before taking saffron supplements.
How to take saffron for PMS
- Dose: about 30 mg a day (roughly 15 threads), split morning and evening — the amount used in the PMS trial.
- Form: saffron water in the morning and kesar milk at night is an easy way to split it.
- Consistency: take it daily across the whole cycle; the trial measured results over two cycles.
- Do not exceed: stay within the limits in our dosage guide.
When to see a doctor
- Pain that stops you from working, studying or sleeping
- Bleeding heavy enough to soak a pad every hour or two
- Periods that are often more than a week late or very irregular
- Any chance you might be pregnant
Who should avoid saffron
Avoid saffron supplements if you are pregnant or trying to conceive, have bipolar disorder or low blood pressure, or take antidepressants, blood pressure medicines or blood thinners without your doctor's advice. Details in saffron side effects, and in Hinglish in kesar ke fayde aur nuksan.
