Siberian peony is a wild peony whose root is used as a calming folk remedy. In Russian it is called maryin koren, or Mary's root. It is taken most often as an alcohol tincture.
The plant grows across Siberia, the Altai and parts of northern Asia. Folk healers used the root for nerves, poor sleep and stomach pain. A tincture of it has been sold in Russian pharmacies for decades as a mild calming drug.
Here is the honest verdict. Good human trials are almost absent, so the calming effect people report is not proven. Long use in tradition is not proof that it works, and it is not proof that it is safe.
The tincture is strongly alcoholic. That matters for who can use it, and it may explain part of the relaxed feeling.
Nobody has shown how Siberian peony works in people.
In animal studies, peony root extracts made rodents less active and more sleepy. Some of that work points to paeoniflorin, a compound that appears to act on brain signals which quiet nerve cells.
Those are lab results. They do not tell you that a spoonful of tincture will calm you.
In test tubes, the root's tannins and gallic acid soak up free radicals (unstable molecules that can damage cells). Whether this happens in your body after you swallow it is not known.
The root also holds small amounts of salicylates, the same family as aspirin. In lab work, peony compounds have slowed blood platelets, the cells that form clots. This has not been measured properly in people, but it is why the blood thinner warnings below are taken seriously.
One plain point is often missed. The pharmacy tincture is about 40 percent alcohol. Alcohol itself makes people feel relaxed and sleepy, so some of the effect may simply be the base.
Common forms include:
- Alcohol tincture of root and leafy top, the usual Russian pharmacy product - Dried cut root, used for a home decoction (a simmered water extract) - Loose root powder - Capsules, sold by some supplement brands outside Russia - Mixed calming drops that blend peony with valerian or motherwort
Labels are not always clear about species. Some products sold as peony contain Paeonia lactiflora, a different plant used in Chinese medicine. Check the botanical name if you care which one you are getting.
Siberian and Russian village healers used Mary's root for centuries. It was given for nerves, sleepless nights, low mood, stomach cramps and coughs. Hunters and herb gatherers dug the roots in autumn.
The plant also entered Mongolian and Tibetan practice, mostly for stomach and womb complaints. In some Siberian areas the dried root was used as a seasoning.
Soviet pharmacy took the remedy up in the mid twentieth century. A standard tincture was registered as a mild calming drug and is still sold in Russia today.
That history shows wide use and official acceptance in one country. It does not show that the remedy was ever tested the way a modern drug is.
Stop and get urgent care if you get a rash with swelling of the lips, face or throat, or any trouble breathing.
See a doctor soon if you faint, bruise or bleed more easily than usual, or feel very drowsy during the day.
See a doctor rather than carrying on if your sleep problem, anxiety or stomach pain lasts more than a few weeks. Fits, chest pain and heavy period bleeding always need medical care, not a herb.
In Russia, peony tincture is a registered over-the-counter calming medicine sold in pharmacies. In the UK, the European Union and the United States it is not approved as a medicine. Where it is sold there, it is a herbal supplement and is not checked like a drug.
