Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Calendula (pot marigold) is a classic skin-soothing herb used topically for minor wounds and irritation. Topical use has modest support; internal use is less studied.
What is Calendula?
Calendula (Calendula officinalis), or pot marigold, is a flowering plant whose petals are used in creams, ointments and teas, mainly for skin and mucous-membrane soothing.
What Calendula is commonly used for
In supplements, Calendula is most often included for skin & anti-aging, gut & digestive health support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Calendula works
Calendula's flavonoids and triterpenoids have anti-inflammatory and wound-supporting activity in laboratory studies, which underlies its long use on minor skin irritation.
What the evidence says
Here's an honest snapshot of what published research suggests about Calendula — including where the evidence is limited.
- Topical calendula has some evidence for soothing minor skin irritation, nappy rash and supporting wound healing, though trials are small. Internal uses are largely traditional.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Calendula rather than relying on marketing claims.
Typical dosage used in studies
Topical products are used as directed; oral teas and tinctures follow traditional preparations without well-standardised dosing. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Calendula is generally well tolerated on skin; people allergic to the daisy family may react. Internal use is best avoided in pregnancy without guidance. As with any supplement, it's sensible to introduce Calendula on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Calendula
Medication & safety check
Herbs interact with prescription medicines more often than people expect — affecting drug levels, bleeding, blood pressure, blood sugar or sedation — and Calendula is no exception. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Calendula is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Calendula with your doctor or pharmacist first.
