For generations, calendula has been used to treat a variety of minor ailments. Calendula, also known as pot marigold, can be used to treat small wounds and burns, ear infections and dermatitis. The herb is generally considered safe. However, experts at the University of Maryland Medical Center (UMMC) suggest that the herb should be avoided by those who are pregnant or trying to become pregnant, or who are breastfeeding; calendula can cause changes in the menstrual cycle. People who have an allergy to other members of the daisy family should also avoid treatment with calendula remedies. As with all herbal remedies, consult your health care provider if you are currently under treatment for a medical condition or taking prescription medications.
Minor Wounds
Georgetown University states that calendula has antibacterial and antiseptic properties and may be useful for healing minor scrapes, cuts and burns. It is also useful for treating insect bites and stings, and provides pain relief while promoting healing.
Ear Infections
Calendula has been used for generations to treat ear infections in children. The herb relieves the pain an ear infection causes, and is as effective as anesthetic ear drops. Commercial preparations are available for this purpose, or a tincture can be made with the herb at home. Either type of preparation should be stored away from heat and light.
Dermatitis
Calendula is also useful for treating both dermatitis and eczema. The herb promotes healing while killing harmful bacteria, and may help prevent infection. It has been used successfully to treat dermatitis in cancer patients, as well.
Commercial ointments containing calendula may be used for this purpose. Remedies may also be prepared at home by steeping calendula flowers in water, then washing broken areas of the skin with this herbal preparation.
