Marigold is a kind of herbaceous plant, which is a kind of carotenoid. It is a pure natural pigment. It has bright color, strong coloring power, good anti-oxidation, safe and non-toxic, and has rich nutritional value. It is the main raw material for refining lutein. The average content of lutein extracted is not less than 12 grams per kilogram. This pigment is a pollution-free natural pigment.
Marigold, also known as "plant lutein", coexists with zeaxanthin in nature. Lutein and zeaxanthin are the main components of plant pigments such as corn, vegetables, fruits, flowers, etc., and are also the main pigments that constitute the macular area of the human eye.
Marigold contains the highest amount of lutein in nature, and the human eye contains high amounts of lutein and zeaxanthin, but these two elements cannot be made by the human body, and must be supplemented by food containing lutein and zeaxanthin, without which the eye goes blind.
Lutein itself is an antioxidant with strong antioxidant effect, which can inhibit the activity of reactive oxygen free radicals, prevent the damage of reactive oxygen free radicals to normal cells, and absorb harmful light such as blue light.
