Marigold not only has medicinal value but also has good ornamental value. In medicine, marigold is mostly used for eye protection.
The marigold extract mainly contains lutein and zeaxanthin. Lutein, also known as "phytolutein", coexists with zeaxanthin in nature. Lutein and zeaxanthin are the main components of plant pigments such as corn, vegetables, fruits, and flowers, and they are also the main pigments that constitute the macular region of the human eye.
In nature, lutein is found in dark green leafy vegetables such as kale, spinach, and flowers such as calendula and marigold. Human eyes contain high amounts of lutein and zeaxanthin, but these two elements cannot be manufactured by the human body and must be supplemented by foods containing lutein and zeaxanthin. Without these two elements, the eyes will be blind. Marigold extract provides a rich source of both elements.
Also, lutein and other carotenoids in the marigold extract are thought to have antioxidant properties. Antioxidants protect cells from damage caused by free radicals, a damaging byproduct of normal metabolism.
