Overview Information

Autumn Crocus is a plant. The seed, bulb, leaves, and flower are used to make medicine. But all parts of the plant are considered toxic.

Despite serious safety concerns, Autumn Crocus is used for rheumatoid arthritis (RA), gout, and an inherited fever disorder called familial Mediterranean fever.


 How Does It Work?

All parts of Autumn Crocus contain colchicine. This is the same active ingredient used in a prescription medication for gout and familial Mediterranean fever. Colchicine works by stopping cells in the body from dividing and growing.

 : Side Effects & Safety 

 When Taken by Mouth:

Autumn Crocus is UNSAFE. It is poisonous, and can cause burning of the mouth and throat, vomiting, diarrhea, liver and kidney problems, blood disorders, nerve problems, shock, organ failure, and death. There have been reports of poisoning when Autumn Crocus was mistaken for onions, wild garlic, or wild leeks and eaten.

If you have gout or familial Mediterranean fever, it is much safer to use colchicine prescribed by your healthcare provider. Prescription colchicine contains a set amount of medicine. The amount of colchicine in Autumn Crocus can vary from plant to plant.


 Special Precautions & Warnings:


© Pregnancy and Breast-Feeding

It's UNSAFE for anyone to use Autumn Crocus, but pregnant women have extra reasons to avoid use. Autumn Crocus might cause birth defects.



 Moderate Interaction

Be cautious with this combination:
