The golden-orange or yellow flowers of calendula have been used as medicine for centuries. Calendula has been used in connection with the following conditions (refer to the individual health concern for complete information): Rating Health Concerns Breast-feeding support (topical for sore nipples) Burns (minor, including sunburn) Conjunctivitis/blepharitis Eczema Peptic ulcer Ulcerative colitis Wound healing (topical) Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use, or the herb or supplement has little scientific support and/or minimal health benefit. Historical or traditional use (may or may not be supported by scientific studies): Calendula flowers were historically considered beneficial for reducing inflammation, wound healing, and as an antiseptic. Calendula was used to treat various skin diseases, ranging from skin ulcerations to eczema.1 Internally, the soothing effects of calendula have been used for stomach ulcers and inflammation. Traditionally, a sterile tea was topically applied in cases of conjunctivitis. Active constituents: Flavonoids, found in high amounts in calendula, are thought to account for much of its anti-inflammatory activity.2 Other potentially important constituents include the triterpene saponins3 and carotenoids. Investigations into anticancer and antiviral actions of calendula are continuing. At this time, insufficient evidence exists to recommend the use of calendula for cancer. Nevertheless, test tube studies have found antiviral activity for calendula.4 5 The constituents responsible for these actions are not clear, however, and the relevance of these actions for human health care has not been established. How much is usually taken? A tea of calendula can be made by pouring 1 cup (250 ml) of boiling water over 1–2 teaspoons (5–10 grams) of the flowers; the tea is then steeped, covered for ten to fifteen minutes, strained, and drunk.6 At least 3 cups of tea are recommended per day. Tincture is similarly used three times a day, at 1/4–1/2 teaspoon (1–2 ml) each time. The tincture can be taken in water or tea. In addition, prepared ointments can be used topically for skin problems, although wet dressings made by dipping a cloth into the cooled tea are also effective. Topical treatment for eye conditions is not recommended, as absolute sterility must be maintained. Are there any side effects or interactions? Side effects are rare with the use of calendula. Some people may experience a skin rash with topical use and should be tested to see if they are allergic to the herb. At the time of writing, there were no well-known drug interactions with calendula. References: 1. Leung A, Foster S.
