What Autumn crocus is, and what it does.

Does it work
No. Do not use this as a supplement. This is not a 'maybe'. It's a hard no. Save your life, not your money.
How much to take
Zero. None. The correct dose of the raw plant is zero. Prescription colchicine doses are tiny (e.g., 0.6mg) and determined by a doctor.
Time to feel it
This is not a supplement timeline. Poisoning from eating the raw plant can begin within two to twelve hours, and any exposure needs urgent medical care.
The first dose
Symptoms of poisoning can appear in 2-24 hours: severe nausea, vomiting, abdominal pain, bloody diarrhea. This requires immediate medical attention.
With regular use
If you survive the initial poisoning, you can expect multi-organ failure, bone marrow suppression, and hair loss. There are no long-term benefits from ingesting the plant.
How well tolerated
Extremely unsafe. One of the most dangerous plants you could ingest. It's often mistaken for wild garlic or ramps, with fatal consequences.
How it feels
Like a severe, life-threatening illness. Intense pain and systemic shutdown. Not a supplement experience.
The overlooked benefit
Its spring leaves look a lot like wild garlic, and that resemblance is how most accidental poisonings happen. The caution here is about foraging, not bottles.

0.5 to 1mg a day is where Autumn crocus works.

Daily maintenanceThe everyday amount, and where most daily supplements sit. This is the one you take month after month.
1.5mgClinical territory. Trials run high on purpose, for a set number of weeks, against one measured outcome. Impressive to hit, and not what a daily product is for.
Above 2mgPast what the research covers. More capsules rather than more effect.

The proof, claim by claim.

These words describe the research, not the molecule's worth. Research strength is how much work stands behind one claim, and it is never a product score.

Questions people ask about Autumn crocus.

Is it safe if I use a very small amount?
No. There is no safe dose. The toxic dose is tiny and varies wildly within the plant itself. It's a gamble with your life.
What if a supplement lists 'Colchicum autumnale'?
Do not buy it. Reputable companies do not sell Autumn crocus. It's a massive red flag for an illegal or dangerous product.
But it's natural, isn't that good?
So is arsenic. 'Natural' does not mean safe. Many of the world's most potent poisons are natural.
How is it different from saffron?
They are completely different plants. Saffron is from *Crocus sativus*. Autumn Crocus is *Colchicum autumnale*. Confusing them is a dangerous mistake.
What are the first signs of poisoning?
A burning throat, severe nausea, vomiting, and diarrhea. If you suspect exposure, go to the emergency room immediately.

No pairing data for Autumn crocus yet.

Nothing on file for Autumn crocus, either from a combination trial or from settled biochemistry. When either lands, it appears here with its source.

No pairing for Autumn crocus has cleared review yet.

Stitching two separate single-ingredient studies into a pairing is the one thing this engine will not do. When a study of the combination itself holds up at source, it lands here with its citation.

No invented synergy. Where actives were studied on their own rather than together, the record shows each on its own evidence, never a combined effect no trial measured.

Research strength. Research strength says how much work stands behind the combination. It is never a product score.

Independent record. Every finding is cited to a named trial, dated, and never written by the brand.

21 pairings are live across the library today. Checked 9 August 2026.
