What is Marigold Flower ?

  • – Marigold flower, also known as Tagetes erecta L., has a long history usage as a medicinal herb; it is commonly found in Europe, North America, and Asia. The flowers and leaves of Marigold flower are the main parts that have the beneficial properties, such as antioxidant, anti-inflammatory, anti-mutagenicity, antiviral and immunomodulatory effects owing to increased polyphenol contents, especially carotenoids, flavonoids, tannins, triterpene, alcohols, saponins and polysaccharides. Recently, its rich content of lutein has been paid a lot of attention to, and it has been used as a source of lutein supplement in the food industry. Many studies and experiments have shown that lutein and zeaxanthin supplementation can maintain eye health, and lower the incidence of various eyes chronic diseases, especially age-related macular degeneration(AMD).
