Pot marigold is a bright orange garden flower used mainly on the skin. The dried petals go into creams, ointments, infused oils and washes. People reach for it for minor cuts, grazes, chapped skin and nappy rash.
It is also called neven in Serbian and Croatian, and gălbenele in Romanian. European folk healers used it for slow wounds and sore skin for centuries.
That long record shows it was trusted. It is not proof that it works, and it is not proof that it is safe.
Here is the honest verdict on the evidence. A handful of small human trials hint at mild help with skin healing, rash and radiation burns. The studies are small and poorly designed, so the results are shaky.
Taken by mouth as a tea or tincture, the human evidence is very thin. Most of what is said about internal use comes from tradition and lab work, not from trials in people.
No one has shown exactly how pot marigold acts on human skin. The ideas below come from lab and animal work, not from people.
In cell studies, calendula extracts appear to speed the growth of skin cells and new blood vessels. In animal wounds, treated skin has closed faster than untreated skin in some reports.
In test tubes, the extract slows some bacteria and fungi. Whether that happens on a real wound is not established.
Cell work also suggests the flower's triterpenes may calm swelling. That is a laboratory finding. It does not prove the cream reduces swelling on your arm.
Pot marigold is sold in many forms. On the skin these are most common:
- Creams, gels and ointments, often listed as 2 to 10 percent extract. - Infused oil, made by steeping petals in a plant oil.
- Tincture, an alcohol extract, usually watered down before use. - Dried petals for a wash, compress or bath soak.
By mouth you may also see:
- Loose dried flowers or tea bags. - Mouth rinses and gargles for sore gums. - Capsules, which are far less common and far less studied.
The petals are also used as a food colour, sometimes called poor man's saffron.
Pot marigold has a long place in European folk care. Writers from the medieval period onward listed it for wounds, sores and skin complaints.
It was pressed into service on battlefields and in farm kitchens. Petals were steeped in oil or fat and smeared on cuts, burns and cracked hands. Washes were used on sore eyes and sore mouths.
In the Balkans, neven ointment was a household item for chapped skin. Romanian folk use of gălbenele followed the same pattern.
The flower was also taken as a tea for stomach complaints and for period pain. These internal uses were never tested well, and modern evidence for them is lacking.
Stop using it and see a doctor if any of these happen:
- The rash, redness or itching gets worse after you start. - A wound turns hot, swollen, smelly or oozes pus. - You get a fever along with a skin problem. - A cut or sore has not improved after about a week. - A leg ulcer or a wound in someone with diabetes is not closing.
Call emergency services if you get a swollen face, lips or throat, hives all over, or trouble breathing. That is a severe allergic reaction.
In the UK and much of the EU, calendula creams can be sold as registered traditional herbal medicines for minor skin problems. That registration is based on long use, not on proof of effect. In the United States it is sold as a cosmetic or a dietary supplement, and is not approved by the FDA to treat any condition.
