Calendula grows as a common garden plant throughout North America and Europe. The golden-orange or yellow flowers of calendula have been used as medicine for centuries. Calendula is an annual garden plant with an anular, branched, hairy stem 1 to 2 feet high.
The leaves are alternate, sessile, spatulate or oblanceolate, dentate with widely spaced teeth, and hairy. From June to October, the plant bears large, yellow or orange, terminal flower heads.
Traditional Uses in Herbal Medicine:
Uses for calendula include the treatment of inflammatory skin disorders, wound healing, and the treatment of other skin conditions. It may also be ingested for its anti-inflammatory and antispasmolytic, as well as its antimetastatic, cancer, cytotoxicity and genoprotective effects.[1,2]
Calendula flowers are useful in reducing inflammation, wound healing, and as an antiseptic. Calendula can be used to treat various skin diseases, ranging from skin ulcerations to eczema. Internally, the soothing effects of calendula is used for stomach ulcers and inflammation. A sterile tea has also been applied in cases of conjunctivitis.
Historically, calendula is found to be antispasmodic, aperient, cholagogue, diaphoretic, vulnerary. An infusion of the flowers can be used for such gastrointestinal problems as ulcers, stomach cramps, colitis, and diarrhoea. It is also useful taken internally for fever, boils, abscesses, and to prevent recurrent vomiting. The fresh juice of the herb or flowers can substitute for the infusion. For external use, a good salve for wound healing [3,4] can be made from dried flowers or leaves, from the juice pressed out of the fresh flowers, or from the tincture. The salve or dilute tincture is good for bruises, sprains, pulled muscles, sores, and boils. The tincture is used internally for gastritis and for menstrual difficulties.
Calendula may be useful in the treatment of:
- Minor burns (including sunburn)
- Wound healing
- Gingivitis (when used as a mouth wash)
- Periodontal disease
- Reduce blood pressure and cholesterol 
Applied locally as a tincture, oil, or lotion, Calendula is considered a natural antiseptic by herbalists. The crushed petals may be combined with olive oil to form an ointment for external application to cuts, bruises, sores, wounds, skin disorders and burns.
The infusion is used to soothe watery, irritated eyes, and for relief in bronchial complaints. It is also used frequently in the treatment of liver disorders. It is thought to induce perspiration in case of fever. Recent clinical studies have shown that calendula flower extracts lower blood pressure and have sedative effects. Marigold is a common adulterant to saffron.
In 1955, an Australian patent was issued for the use of marigold extracts in the treatment of burns in humans.
The flavonoids, found in high amounts in calendula, account for much of its anti-inflammatory activity; triterpene saponins may also be important. Calendula also contains carotenoids. Investigations into anticancer and antiviral actions of calendula are continuing. There is evidence suggesting use of calendula for some viral infections. The constituents responsible for these actions are not entirely clear. A comprehensive description of the active componants in Calendula officinalis available at: doi: 10.3390/antiox8110559 .
