In addition to being an ornamental plant, marigold has a very high utilization value. Marigold extract is rich in lutein. Lutein is a natural pigment that widely exists in vegetables, flowers, fruits, and some algal organisms, and is mostly used in food, cosmetics, tobacco, medicine, and poultry feed.
Lutein is an excellent antioxidant with the characteristics of strong stability, no toxic side effects, and high safety.
As a food additive, lutein can resist cell and organ damage caused by free radicals in the human body, thereby preventing cardiovascular sclerosis, coronary heart disease, and tumor diseases caused by aging.
The United States has been extracting lutein from marigolds since the 1970s. It was first added to chicken feed to improve the nutritional value of eggs. Lutein can also be used in cosmetics, feed, medicine, aquatic products, and other industries.
Marigold flower supplements can resolve phlegm and relieve cough, clear heat, and detoxify, and can also be made into sedatives and bacteriostatic agents.
