Saffron For The Brain (& More)
In yesterday’s edition of 10almonds, one of the items in the “health news from around the world” section was:
Clinical trial finds herbal medicine Sailuotong effective for brain health in older people
But, what is it?
❝SaiLuoTong (SLT) is a modern compound Chinese herbal medicine preparation in capsule form containing standardized extracts of Panax ginseng, Ginkgo biloba, and Crocus sativus L❞
We’ve written previously about ginseng and ginkgo biloba:
So, what’s this about Crocus sativus L.?
That is the plant better known as saffron. And, for all its wide availability (your local supermarket probably has at least a tiny amount in the spice section), there’s a reason we don’t see much of it:
❝Saffron blooms only once a year and should be collected within a very short duration. It is picked during 3–4 weeks in October-November. The method for the cultivation of saffron contributes greatly to its high price. According to some reports, this species is a sterile triploid and so does not produce fertile seeds. Germination can take 1–6 months at 18°C. It takes 3 years for plants to flower from seed.❞

That’s fascinating, but what does it do for us?
Well, in the words of El Midaoui et al. (2022):
❝In the frame of a double-blind-placebo-controlled study, 30 mg per day supplementation with saffron for 16 weeks resulted in improved cognitive function in patients suffering from mild to moderate Alzheimer’s disease.
Moreover, the follow-up of this study in which the authors evaluated the effects of saffron (30 mg/day) for 22 weeks showed that saffron was as effective as donepezil in the treatment of mild-to-moderate Alzheimer’s disease❞

Not just that, but it also has powerful antioxidant and anti-inflammatory properties beyond the brain (though the brain is where research has been most focused, due to its neuroprotective effects).
(this, too, is a full research review in its own right; we’re getting a lot of “bang for buck” on papers today)
And more?
Yes, and more. Lots more. To bullet-pointify even just the abstract from another research review:
- Saffron has been suggested to be effective in the treatment of a wide range of disorders including coronary artery diseases, hypertension, stomach disorders, dysmenorrhea and learning and memory impairments.
- In addition, different studies have indicated that saffron has anti-inflammatory, anti-atherosclerotic, antigenotoxic and cytotoxic activities. (This is all good; the cytotoxic activities are about killing cancer cells)
- Antitussive effects of stigmas and petals of C. sativus and its components, safranal and crocin have also been demonstrated.
- The anticonvulsant and anti-Alzheimer properties of saffron extract were shown in human and animal studies.
- The efficacy of C. sativus in the treatment of mild to moderate depression was also reported in clinical trial.
- Administration of C. sativus and its constituents increased glutamate and dopamine levels in the brain in a dose-dependent manner.
- It also interacts with the opioid system to reduce withdrawal syndrome.
- C. sativus and its components can be considered as promising agents in the treatment of nervous system disorders.

Is it safe?
The effective dose is 30mg/kg and the LD50 is more than 20g/kg, so yes, it’s very safe. Given the price of it, this also means that if you’re the size of this writer (a little over 70kg, or a little over 150lbs) to poison yourself effectively you’d need to consume about 1.4kg of saffron at a time, which would cost well over $6,000.
Where can I get it?
Your local supermarket probably has a tiny amount in the spice section, or you can get better prices buying it in “bulk” online. Here’s an example product on Amazon, for your convenience 🙂
Enjoy!
