An herbal extract from the Calendula officinalis flower (pot marigold) used in skincare for its anti-inflammatory, wound-healing, and skin-soothing properties. Calendula contains triterpene saponins, flavonoids, and carotenoids that promote tissue repair and reduce inflammation.
Calendula officinalis (pot marigold, not to be confused with ornamental marigolds in the Tagetes genus) has been used in European herbal medicine for over 800 years for wounds, burns, rashes, and inflammatory skin conditions. Modern research has validated many traditional uses, identifying specific bioactive compounds responsible for calendula's skin-healing effects.
Triterpenoid saponins (particularly faradiol and arnidiol) are the primary anti-inflammatory compounds, shown to inhibit edema and inflammatory mediator release at levels comparable to indomethacin in some animal studies. Flavonoids (quercetin, isorhamnetin, narcissin) provide antioxidant and anti-inflammatory support. Carotenoids (lutein, zeaxanthin, beta-carotene) contribute antioxidant activity and give calendula its golden-orange color. Polysaccharides stimulate immune cell activity and promote wound closure.
A 2009 randomized controlled trial in the Journal of Clinical Oncology found calendula cream significantly reduced the severity of radiation dermatitis in breast cancer patients compared to the standard treatment (trolamine). Multiple smaller studies confirm calendula's efficacy for diaper rash, minor burns, and wound healing. The European Medicines Agency (EMA) has approved calendula preparations for minor wound healing and mild skin inflammation.
Calendula appears in skincare as infused oils (calendula flowers steeped in carrier oil), extracts (alcohol or glycerin-based tinctures), and creams/balms. It is one of the safest botanicals for sensitive and infant skin, with extremely low allergenicity. The primary caution: people with ragweed, daisy, or chrysanthemum allergies (Asteraceae family) may have cross-reactive sensitivity to calendula.
Yes. Calendula is one of the most widely used botanical ingredients in baby skincare products specifically because of its excellent safety profile and gentle soothing properties. It is commonly found in diaper creams, baby lotions, and baby bath products. The only caution is for families with known Asteraceae (ragweed/daisy family) allergies.
Yes. Place dried calendula petals in a glass jar and cover with a carrier oil (olive, jojoba, or sweet almond). Seal and place in a sunny window for 4 to 6 weeks, shaking daily. Strain through cheesecloth. The resulting calendula-infused oil can be used directly on skin or as a base for homemade balms and salves.
