What is Calendula（Marigold）?

The calendula herbal plant is known since ancient times. It is also called as pot marigold, scientific name calendula officinalis. The name Calendula comes from Latin world “calendae” which means calendar and this designates the 1st day of every month. This name is referred since the time of ancient Romans when calendula flowering occurred every month of the year even in wintertime if it was not very cold.

Marigold or more commonly Calendula has been used medicinally for centuries. Traditionally, it has been used to treat conjunctivitis, blepharitis, eczema, gastritis, minor burns including sunburns, warts, and minor injuries such as sprains and wounds. It has also been used to treat cramps, coughs, and snake bites. Calendula has a high content of flavonoids, chemicals that act as anti-oxidants in the body. Anti-oxidants are thought to protect body cells from damage caused by a chemical process called oxidation. Oxidation produces oxygen free radicals, natural chemicals that may suppress immune function.

Calendula has been considered beneficial in reducing inflammation and promoting wound healing. It has been used to treat a variety of skin diseases and has been seen effective in treatment of skin ulcerations, eczema, juvenile acne and dry phthiriasis. Improvement has been seen in as little as 3-4 days of treatment according to the Universitatea de Medicina si Farmacie.

Calendula is one of several herbs used traditionally to treat conjunctivitis and other eye inflammations as it helps to reduce the swelling and redness of eye infections. It is also believed that calendula may have some anti-spasmodic action, and as such, it has been used to relieve menstrual cramps.

Chemical constituents of Calendula（Marigold）Extract

The petals and pollen of Calendula officinalis contain triterpenoid esters and the carotenoids flavoxanthin and auroxanthin (antioxidants, and the source of the yellow-orange coloration). The leaves and stems contain other carotenoids, mostly lutein (80%) and zeaxanthin (5%), and beta-carotene. Plant extracts are also widely used by cosmetics, presumably due to presence of compounds such as saponins, resins and essential oils.

The flowers of Calendula officinalis contain flavonol glycosides, triterpene oligoglycosides, oleanane-type triterpene glycosides, saponins, and a sesquiterpene glucoside.

Benefits of taking Calendula（Marigold）Extract supplements:

Eye diseases

The leaves and stems contain other carotenoids, mostly lutein (80%) and zeaxanthin (5%), and beta-carotene.Zeaxanthin for eye health benefit, cataracts, macular degeneration, eye diseases Astaxanthin supplement benefit to reduce lipid peroxidation and free radical oxidation prevention Of the many carotenoids circulating in human bloodstream, only lutein and zeaxanthin are accumulated in significant quantities throughout the tissues of the retina of the eye. Lutein is a carotenoid which has become popular as a dietary supplement either by itself, or combined with zeaxanthin and other carotenoids and vitamins for the prevention of visual disorders such as macular degeneration or to improve eyesight. Dietary zeaxanthin is considered a critical nutrient in the eye and in the fight against macular degeneration. Zeaxanthin accumulates in the human macula lutea and protects retinal cells from blue light damage.

Dermatitis

The effect of Calendula officinalis flower extract was investigated against experimentally induced thermal burns in rats. The animals treated with the extract showed significant improvement in healing when compared with untreated animals. The histopathological analyses of skin tissue also shows evidence of the increased healing potential of the extract after burn injury (Chandran 2008).

A randomized controlled trial demonstrated positive effects of ointment with marigold extract on venous ulcer epithelialization in the lower leg. The total surface of all the ulcers decreased by 41.7% compared with 14.5% in the placebo group. In seven patients who applied the ointment containing marigold extract (twice a day for 3 weeks), complete epithelialization was achieved. Complete epithelialization was achieved in only 4 patients receiving the placebo treatment, which consisted of saline solution dressings applied to ulcers for 3 weeks. The results suggests that C. officinals promotes statistically significant acceleration of wound healing (Duran 2005).

Calendula officinalis may be a potential therapy in cases for cheilitis, which is characterized by inflamation and cracking of the lips, espeically at the corners of the lips. An eighteen-year-old man, whose symptoms persisted despite daily use of topical corticosteroids, improved markedly within a week of being prescribed Calendula officinalis ointment (Roveroni-Favaretto 2009).

gingivitis

Calendula extract toothpaste has also be recommended as an adjunctive procedure effective for the improvement of gingival inflammation. Brushing with calendula toothpaste led to significant reductions in plaque index, gingival index and bleeding on probing in a prospective, double-blind clinical study of 40 volunteers with established gingivitis (Amoian 2010).

In a double-blind placebo controlled trial, a marigold therapy using a Tagetes patula preparation, plus a protective dressing, effectively reduced the width of the lesion and level of pain of Gunions (Khan 1996).

ear infections

Calendula has been studied for reducing pain caused by ear infections. Some human studies suggest that calendula may possess mild anesthetic properties equal to those of similar non-herbal eardrop preparations. Further studies are needed before a recommendation can be made in this area (Sarrell 2001).
