Overview
Calendula is a cheerful annual herb with vibrant orange and yellow daisy-like flowers, native to the Mediterranean and widely cultivated worldwide. One of the most versatile and gentle medicinal herbs, calendula is particularly celebrated for its remarkable skin-healing, anti-inflammatory, and antimicrobial properties. Its bright flowers contain a rich array of flavonoids, carotenoids, and triterpenes that make it one of the most effective topical herbs for wound healing, skin conditions, and mucous membrane support.
Traditional Use
Calendula has been used medicinally since at least the 12th century in Europe. Medieval herbalists used it for skin conditions, wounds, and digestive complaints. During the American Civil War and World War I, calendula was used as a field dressing for wounds. Traditional herbalists across Europe prescribed calendula for skin conditions, menstrual irregularities, and digestive inflammation. In Ayurvedic medicine, calendula is used for skin diseases and as a wound healer.
Key Active Compounds
Triterpenoid Saponins (Oleanolic Acid Glycosides)
Primary anti-inflammatory compounds that inhibit inflammatory enzymes and reduce edema. Responsible for much of calendula's wound-healing activity.
Flavonoids (Quercetin, Isorhamnetin, Narcissin)
Potent antioxidant and anti-inflammatory compounds that reduce oxidative stress, inhibit inflammatory pathways, and support tissue repair.
Carotenoids (Beta-carotene, Lutein, Zeaxanthin)
Antioxidant pigments responsible for the orange-yellow color. Support skin health, reduce inflammation, and provide antioxidant protection.
Polysaccharides
Immune-stimulating and wound-healing compounds that promote fibroblast proliferation and collagen synthesis.
Evidence-Based Benefits
Wound healing and skin repair
Strong evidenceMultiple clinical trials confirm calendula significantly accelerates wound healing, reduces inflammation, and promotes tissue regeneration. Shown to be superior to petroleum jelly for episiotomy healing.
Anti-inflammatory skin conditions
Moderate evidenceClinical studies show calendula cream effectively reduces symptoms of eczema, contact dermatitis, and diaper rash. Anti-inflammatory compounds reduce redness, swelling, and itching.
Antimicrobial activity
Moderate evidenceCalendula extracts demonstrate activity against bacteria, fungi (including Candida), and viruses in laboratory studies, supporting its traditional use as a wound antiseptic.
Digestive and mucous membrane support
Some studiesInternal use of calendula tea soothes inflamed mucous membranes in the digestive tract, supporting healing of gastritis, peptic ulcers, and inflammatory bowel conditions.
