Marigold marsh, or Calendula officinalis, is a plant with bright orange or yellow flowers known as a wound-healing, stimulating and antiseptic remedy, according to the University of Maryland Medical Center. Calendula flower preparations have long been considered topical remedies for burns, bruises, cuts, varicose veins and rashes. In European folk medicine, marigold was also recommended for use internally as an antispasmodic, antiviral, bactericidal, a stomach upset treatment, for ulcers and eczema.
Chemistry
Flavonoids, saponins, lutein and beta-carotene have been isolated and may contribute to calendula's anti-inflammatory and wound-healing actions topically, according to Sloan-Kettering Cancer Center. The high content of flavonoids, plant-based antioxidants, protects the body against free radicals. Calendula is also believed to stimulate granulation and increase protein and collagen at a wound site.
Clinical Use
Calendula is accepted as a topical treatment for diaper rash and other mild skin irritations or inflammations. The plant has an estrogenic action because of its sterol and saponin content, which is why it's a useful regulator of female hormones. Calendula cream is also used to treat hemorrhoids. Herbal remedies containing marigold extract is effective in reducing earache in children with acute otitis media.
Applications
Most topical use of calendula is in the form of an ointment or cream that is applied topically several times daily. A tea can be made for mouthwash or topical treatment. For earaches, ear drops containing calendula extracts are used.
Precautions
Topical use of calendula is generally safe for babies, young children and the elderly. There have been rare reports of allergic reactions with topical use of calendula. Precautions in pregnancy are advised since marigold can stimulate uterine contractions. A consultation with a expert herbalist or health practitioner is recommended before taking any herbal remedies.
