The calendula plant, also called Calendula officinalis or simply marigold, is a flowering plant that has been used as an ingredient in medicines since the 12th century. To treat various skin conditions, calendula is generally made into a topical preparation. Although more scientific evidence is needed, many people use calendula topical ointments to treat a variety of skin conditions.
Preparations
The petals of the calendula flowers are the principle active ingredients in calendula products used to treat skin conditions. The petals of the flowers, either fresh or dried, are used to make creams and ointments, which are then applied to the affected area of the skin. The University of Maryland Medical Center advises using an ointment that contains 2 to 5 percent calendula, and applying it to the appropriate area of the skin three to four times daily or as needed.
Skin Diseases
Topical preparations of calendula have been used to treat inflammation of the skin after radiation treatments for cancer, a condition called radiation-induced dermatitis. Calendula has also been used to treat include scrapes, eczema, burns, and wounds that are healing poorly. Calendula-based creams are even used to treat hemorrhoids and varicose veins. These creams are especially common in Germany, but are available in the United States as well.
Evidence
The use of calendula as a treatment for various skin conditions is supported primarily by tradition, but there has been little rigorous scientific testing to support or negate these claims. While there has been some scientific studies showing that calendula helps treat radiation-induced dermatitis, very few studies have investigated the claim that it effectively treats eczema and burns and supports wound healing. Scientific testing in the future is necessary to accurately determine the effectiveness of calendula for treating skin conditions. Check with your doctor before using calendula to see what type of treatment is right for you.
Possible Adverse Effects
Ointments and creams made from the calendula flower are generally considered safe. However, the University of Maryland Medical Center advises not to apply calendula ointments to open wounds, except under direction from a medical professional. Calendula also seems to affect the menstrual cycle, so pregnant women and couples trying to get pregnant should not use this natural treatment. Some people may be allergic to calendula; especially at risk are those with allergies to chrysanthemums or ragweed.
