In the small amounts used in cooking, such as two or three threads in a glass of milk, saffron is generally considered safe for most pregnant women, though many doctors suggest waiting until after the first trimester. Large amounts are a different matter: high doses can stimulate the uterus and should be avoided. Saffron will not make a baby fairer. Speak to your own doctor before adding it to your diet, especially if your pregnancy is high-risk.
Please read this first. This article is general information, not medical advice. Every pregnancy is different, and your doctor or midwife knows yours.
In many families, a glass of warm milk with a few strands of kesar is part of pregnancy, handed down from mothers, mothers-in-law and grandmothers. It is a lovely tradition, and a comforting one. It also deserves a clear-eyed look, because saffron is a strong spice and the amount matters more than anything else.
What the tradition says
Kesar milk is traditionally given in pregnancy for better digestion, easier sleep, a lighter mood, relief from cramps and the "glow" of pregnancy. Some of these are about warm milk at bedtime as much as saffron. Others simply haven't been studied properly in pregnant women.
One belief can be put down firmly. Saffron does not make a baby fairer. A baby's skin tone is decided by genes, and nothing the mother eats changes it.
Myths and what is actually true
What people say | What is true |
|---|---|
Saffron makes the baby fair | No. Skin colour is inherited. No food changes it |
More saffron means more benefit | No. Benefit doesn't grow with the dose, but risk does |
Saffron milk is safe from day one | Many doctors prefer you wait until after the first trimester |
Saffron can safely bring on labour | Never use saffron to try to start labour yourself |
Any red threads from the market are saffron | Fake saffron is common and is often dyed with colours that are not meant to be eaten |
How much is a sensible amount?
This is the heart of it. Saffron in food amounts is a world away from the doses that cause concern:
Amount | Roughly | What it means |
|---|---|---|
1 thread | about 2 mg | A single strand |
3 threads, a glass of kesar milk | about 6 to 7 mg | The traditional amount |
10 threads, a dish for four | about 22 mg | Shared across four plates |
1 gram | about 450 threads | A month or more of daily kesar milk |
5 grams | more than 2,000 threads | Around the level medical reviews associate with harmful effects |
A glass of kesar milk holds a few milligrams. The worry is about grams. The gap between them is several hundred times, which is why the amount in a glass of milk is generally considered safe and why "a little more for luck" is a bad idea.
Which trimester?
Stage | What doctors commonly advise | Why |
|---|---|---|
First trimester, weeks 1 to 12 | Many suggest avoiding saffron | This is when the concern about uterine stimulation matters most |
Second trimester, weeks 13 to 27 | Two or three threads, now and then, if your doctor agrees | When the tradition usually begins |
Third trimester, weeks 28 to 40 | Small amounts, if your doctor agrees | Don't use it to try to bring on labour |
Breastfeeding | Cooking amounts are generally considered fine | Little is known about larger amounts |
Small clinical studies have looked at saffron in late pregnancy and labour, but they were run under medical supervision. They are not a reason to dose yourself.
How to make kesar milk the gentle way
- Warm a glass of milk until it steams. Don't let it boil hard.
- Add two or three threads, not a pinch and not a spoonful.
- Cover it and leave it for five to ten minutes, so the colour and aroma come out.
- Sweeten lightly if you like, with a little sugar or jaggery.
- Drink it a few times a week rather than daily, unless your doctor is comfortable with daily.
When to stop and call your doctor
Stop taking saffron and speak to your doctor straight away if you notice:
- bleeding or spotting
- cramps or tightening that could be contractions
- dizziness, nausea or vomiting that is new
- itching, a rash, swelling or any sign of an allergic reaction
Why purity matters even more here
Fake saffron is common, and it is often coloured with dyes that were never meant to be eaten. That is a poor bargain at any time and a worse one in pregnancy. If you use saffron while pregnant, use saffron you can trust: a named cut, an ISO 3632 lab report, and threads that pass the water test, which is described in our guide to spotting fake saffron.
Frequently asked questions
Can I eat biryani or kheer with saffron while pregnant?
Generally, yes. The saffron in a dish shared between several people is a small amount per serving. Check with your doctor if you have been told to avoid it altogether.
Is kehwa safe in pregnancy?
Kehwa is made with green tea, so it contains caffeine as well as saffron. Most guidance asks pregnant women to limit caffeine, so count kehwa towards your daily total and ask your doctor what limit is right for you.
Should I take saffron capsules or supplements?
Not unless your doctor prescribes them. Supplements hold far more saffron than food does, and their safety in pregnancy hasn't been established.
Can saffron cause a miscarriage?
Very large doses have been linked to stimulating the uterus, which is why the amount matters so much. Saffron in normal food amounts has not been shown to cause miscarriage, but if you are worried, or have had a miscarriage before, leave it out and talk to your doctor.
When is the best time of day for kesar milk?
In the evening, an hour or so before bed, is how most families have it. Warm milk at bedtime is soothing in its own right.
