Saffron, from the pantry to the clinical trials

The first time I cooked with real saffron I was standing in a rented kitchen in Valencia, with a paella pan the size of a bicycle wheel and a neighbor who insisted on supervising. She crumbled a pinch of red threads into a spoonful of warm stock and made me wait ten minutes before it went in the pan. The smell, somewhere between honey and hay, has stayed with me for twelve years.

When I got home to Portland I went looking for saffron and found it in a tiny plastic box at the grocery store for $14. It did not smell like Valencia. That started me reading about how much of the saffron sold in the world is the real thing, and the reading did not stop there.

Why a cooking journal ended up reading clinical trials

Saffron is not just a spice. For centuries it was used in Persian and Indian medicine, and in the last twenty years researchers in Iran, where most of the world's saffron is grown, have run a series of small clinical trials on it. Some of those trials looked at mood. Some looked at memory in people with early Alzheimer's.

Two natural compounds get most of the scientific attention: crocin, the pigment that turns a pot of rice gold, and safranal, the source of that honey-and-hay smell. In the lab, crocin behaves like an antioxidant, calms inflammation and appears to slow the sticky amyloid clumps linked to Alzheimer's (Finley, 2017). That is lab work, not proof in people. But it is why the trials got started.

What I have written so far

The memory trials, in plain words. What the Tehran studies actually did, who was in them, and how much weight to put on the results.
How to buy real saffron. The tricks used to stretch it, the simple tests you can do at home, and what a fair price looks like.
Saffron and mood. The research on saffron for low mood is actually stronger than the memory research, which surprised me.

Saffron in supplements

Saffron has become a popular ingredient in memory and mood supplements. When it shows up on a label, the questions I ask are the same ones I ask at the spice shop: how much is in there, and how do I know it is real? If you want a balanced overview before buying anything, I found a sober summary of saffron and memory that sticks close to the studies.

A quick word of caution. Saffron in the amounts used for cooking is very safe. The research doses, around 30 mg a day of extract, have also been well tolerated in trials. But very large amounts are toxic, pregnant women should avoid saffron supplements, and anyone on antidepressants should mention it to their doctor. The NCCIH guide to using dietary supplements wisely is a good general read before trying any herbal product.

A note on what this journal is not

I am a cook, not a doctor or a scientist. I read the studies carefully and link to every one so you can read them too. When I am not sure about something, I say so. And I still think the best use of saffron is a pot of rice on a Sunday with people you like.
