Calendula officinalis for long—also known as the “Pot Marigold”— is a plant within the family Asteraceae. It is native to the Mediterranean region of Europe, although it can now be found around the world. Calendula plants stand out with bright petals, usually yellow or orange, growing 1-2 feet tall. Its narrow petals are described as a sunray shape. In addition to being a culinary tool, Calendula is best known for its medicinal uses.
Calendula has can be used to relieve many types of skin conditions that may cause dry, itchy, or irritated areas. It soothes skin experiences symptoms of eczema, dermatitis, and dandruff. By promoting the production of collagen, an essential protein for glowing skin, Calendula aids in sustaining soothed, hydrated skin. Although strong in effect, the gentleness of the herb often makes Calendula a skin care benefit that can be enjoyed even by many of those with skin sensitivities.
One of the prominent Calendula benefits is its ability to reduce scarring when used to treat wounds. The Calendula properties that benefit wound healing apply to the scarring process as well. Calendula increases blood flow to the injury, promotes a speedy and healthy healing process, free of infection, and encourages growth of healthy new tissue. In the cases of skin ulcers like chicken pox and acne, the herb softens and soothes the skin, preventing inflammation, boosting the immune response, which allows wounds to heal quickly and cleanly.
Reactive oxygen species (ROS) generated from UV-B radiation have the capacity to cause oxidative decomposition which leads to the formation of toxic components as well as lipid peroxidation. Considering this fact, the present study was performed to evaluate the effect of a cream (O/W) containing the essential oil of Calendula officinalis on biochemical parameters of the skin of albino rats against UV-B radiation. The fingerprint analysis of Calendula essential oil was performed by HPLC with special reference to 1,8-cineole and α-pinene. The results indicated that the treatment with creams containing 4% and 5% of Calendula essential oil caused a significant decrease in the malonyldialdehyde level, whereas the levels of catalase, glutathione, superoxide dismutase, ascorbic acid, and the total protein level were significantly increased after 1 month of daily irradiation and treatment when compared to untreated control groups. The results suggest that the cutaneous application of the essential oil of Calendula prevents UV-B-induced alterations in the level of antioxidants in skin tissue.
