Properties of Marigold Extract

Marigolds contain numerous antioxidant carotenoids that give the petals their bright orange and yellow colors. An antioxidant is a compound that helps protect the cells from damage caused by free radicals, or hazardous molecules. Lutein is a naturally occurring molecule found in dark green leafy vegetables such as spinach, kale and collard greens and numerous studies have suggested that lutein intake fortifies the macula of the eye. The macula filters out blue wavelength light from the sun and artificial light, suppressing the oxidation of retinal cells that can otherwise cause degenerative eye disease.
Lutein not only reduced the number of tumors in the breast, it also prevented new cancer cells from developing. Researchers found that even in small dietary amounts, the lutein from marigolds had a positive effect. Marigold has also been found effective against leukemia, colon and melanoma cancer cells.
Free radicals are the by-products of normal body functions or environmental factors such as cigarette smoke or pollution. Free radicals can damage cells to the point that they damage DNA, and can lead to disease and various forms of cancer. High intake of antioxidants helps combat free radical damage. The primary carotenoids in marigolds are lutein and zeaxanthin, often paired together, and lycopene. The Linus Pauling Institute reports that lutein and zeaxanthin are the only antioxidants that are found in the retina of the eye, where they protect the eye from the development of cataracts and macular degeneration. Lycopene is reported to reduce the risk of prostate cancer and heart disease.
