A personal story about old wisdom, modern science, and the tiny golden threads that connected them.
I'll be honest with you. When my grandmother first showed up at our house with a small steel dabba of saffron and announced that my wife Rania would be drinking kesar milk every night, I thought it was sweet but unnecessary.
We were educated people. My wife had a gynaecologist. We had prenatal vitamins, apps that tracked the baby's growth week by week, and a carefully curated list of foods to eat and avoid. What could a few strands of dried flower do that our modern pregnancy protocol couldn't?
A lot, it turns out.
The Nightly Ritual I Didn't Take Seriously
My grandmother — we call her Dadi — didn't ask permission. She just started appearing every evening around 8 PM with a small glass of warm milk, golden-orange and fragrant, a few crimson threads floating at the surface. She'd hand it to Rania with the kind of quiet authority that older women in Indian families carry without even trying.
Rania drank it. I watched from the couch, mildly amused.
"Dadi, what exactly does this do?" I asked one evening.
"It calms her. It calms the baby. It helps her sleep. It is what we have always done," she said, in the tone of someone who has no patience for further questions.
I nodded. I let it go. But somewhere in the back of my mind, the skeptic in me was still rolling his eyes.
What Changed My Mind
Three things changed my mind: watching my wife, reading the research, and eventually asking her gynaecologist.
First, Rania herself. She started sleeping better around the fifth month, right around when the kesar milk ritual had become firmly established. Her mood, which had been understandably volatile in the second trimester, seemed more even. She had less anxiety — a near-constant companion in those early months — and her digestion, which had been giving her trouble, calmed down. She credited the kesar milk. I wasn't ready to.
Second, the research. I'm the kind of person who Googles things. And when I finally looked into what saffron actually contains and what it actually does, I stopped rolling my eyes.
What Saffron Actually Does: The Science My Grandmother Knew by Heart
Saffron's active compounds — primarily crocin, crocetin, and safranal — have been the subject of serious clinical study for the past two decades. Here is what the research says, in plain language:
1. It Has Genuine Antidepressant and Anxiolytic Effects
Multiple clinical trials have found that saffron has measurable antidepressant effects comparable to low-dose SSRIs, without the pharmaceutical risks. The mechanism involves serotonin and dopamine pathways — the same pathways disrupted by prenatal mood disturbances. Anxiety during pregnancy is extraordinarily common. Saffron's safranal and crocin compounds address it without introducing the risks that come with medication.
Dadi didn't know the word "safranal." She just knew her daughter-in-law was calmer when she drank kesar milk.
2. It Improves Sleep Quality
Saffron's safranal compound has demonstrated sedative and relaxing properties in clinical studies. Warm kesar milk at night — the exact ritual Dadi was insisting on — is one of the most time-tested remedies for the sleep disturbances that make pregnancy so exhausting, particularly in the second and third trimesters.
3. It Supports Healthy Blood Pressure
The crocin and safranal in saffron have shown antihypertensive effects in studies. Prenatal hypertension is one of the more serious pregnancy complications. Saffron isn't a substitute for medical care, but a regular, moderate intake of pure kesar as a dietary supplement is a genuinely sensible addition to a pregnancy wellness routine.
4. It Has Anti-Inflammatory and Digestive Benefits
Saffron has anti-inflammatory effects on the gastrointestinal tract and may reduce gastric acidity. Warm kesar milk in the evenings is soothing to a stomach dealing with the pressures of a growing baby — morning sickness, heartburn, acid reflux. Rania's digestive troubles improved. I thought it was coincidence. I'm no longer so sure.
5. It Contains Nutrients That Matter During Pregnancy
Saffron contains iron (which fights pregnancy anaemia), vitamin C (which aids iron absorption), vitamin A (critical for foetal development), and manganese. None of these are at replacement levels in a few threads of kesar — but every contribution counts when the body is working as hard as it does during pregnancy.

The Myth Dadi Also Believed (That I Have to Address)
There is one thing Dadi believed that science does not support: that kesar milk would make the baby fairer.
This is a widespread belief in Indian families, and I want to be clear about it — there is no scientific evidence that drinking saffron milk during pregnancy affects a baby's complexion. Skin colour is determined by genetics. No food, supplement, or drink consumed during pregnancy alters the melanin production that determines complexion.
The real benefits of kesar milk during pregnancy — mood support, better sleep, digestive comfort, gentle anti-inflammatory action — are all evidence-based. The complexion belief is not. I love Dadi. And part of respecting her is being honest about this.
When and How Dadi Made It: The Recipe She Never Measured
Dadi made the kesar milk the same way every night. She never used measuring spoons. She never consulted a recipe.
• Warm the milk slowly — never boil it.
• Add four or five threads of saffron to a teaspoon of warm milk first, and let it steep for ten minutes.
• Combine with the warm glass of milk.
• A pinch of cardamom.
• A small piece of mishri (rock sugar) to sweeten.
• Served at exactly the right temperature — warm enough to comfort, not hot enough to burn.
The steeping step, I later learned, is critical. Pre-soaking the saffron threads in a small amount of warm liquid before adding them to the full glass allows the crocin to release properly. Dropping threads directly into a boiling pan destroys the safranal — the compound responsible for saffron's aroma and many of its benefits.
Dadi had no idea about crocin or safranal. She just knew how to make it work.

The Question of Quality: Why Dadi's Saffron Wasn't Just Any Saffron
This is something I didn't think about at all until I started reading, and it matters enormously.
Dadi's saffron came from a specific source — a small packet that a relative brought from Pampore, Kashmir, the only GI-tagged saffron growing region in India. She kept it in a small steel tin, and she was very particular about it. She would not use the saffron sold in the local supermarket. "That is not real kesar," she'd say, dismissively.
She was right.
The Indian market is flooded with adulterated saffron — coloured corn silk, dyed threads, Iranian saffron repackaged as Kashmiri. Many of these products contain artificial dyes whose safety during pregnancy is entirely unknown. A product that turns milk immediately red (rather than a slow golden release over 10–15 minutes) is almost certainly not pure saffron.

The version of this ritual that Dadi practiced — and that actually produces the benefits — requires genuine Kashmiri Mongra saffron. Not the cheaper substitute.
How Much Is Actually Safe? (The One Thing Dadi Got Wrong)
In all her wisdom, Dadi was a little heavy-handed sometimes. Some evenings she'd add six or seven threads. Some evenings, when she was feeling generous, more.
The clinical consensus is that 3–5 threads per day is the correct amount during pregnancy. The safe upper limit is around 1.5 grams per day. Doses above 5 grams per day can stimulate the uterus — saffron in very large quantities is a uterine stimulant, which is also why it should be avoided entirely in the first trimester.
The traditional recommendation to start kesar milk from the fifth month onwards — which Dadi followed instinctively — aligns perfectly with medical guidance. The first trimester carries the highest risk of miscarriage, and large amounts of saffron are contraindicated. The second trimester, once the pregnancy is stable, is when the gentle mood, sleep, and digestive benefits are most valuable.

What I Told My Brother When His Wife Got Pregnant
My younger brother Arif called me last year. His wife was pregnant. His mother-in-law had suggested kesar milk. He called me to ask what I thought.
I told him everything I've written here. I told him about the research. I told him about the sleep improvement. I told him about the importance of using pure, verified saffron — not the corner shop variety. I told him about the first trimester precaution, and about checking with the gynaecologist first. I told him about the myth around skin colour that he should gently correct without dismissing the practice.
And then I told him: your mother-in-law is right. Let her do this. Just make sure the saffron is real.
The Lesson I Carry Now
My daughter is fourteen months old. She sleeps beautifully. She is curious and calm and — for what it is worth — has her mother's eyes and my terrible sense of direction.
I don't know how much of that is kesar milk. Probably none of the last part. But I know that the months of Rania's pregnancy where she drank it every night were calmer months. Easier nights. A less anxious second trimester. And I know that the science supports a real, if modest, explanation for each of those improvements.
Dadi didn't have a peer-reviewed journal. She had generations of observation, passed down through families in Kashmir and across India, refined over centuries into a simple nightly ritual: warm milk, a few golden threads, cardamom, mishri, patience.
Turns out that's a pretty good evidence base.
