What is African Marigold?
Tagetes erecta (African marigold) is a flowering plant from the Asteraceae family, native to Central and South America and now cultivated worldwide.
The flowers are a natural source of lutein, a carotenoid that plays an important role in maintaining eye health and supporting antioxidant protection.
Historical uses
Historically, African marigold has been used in various cultural practices:
- Applied topically for minor skin concerns
- Used as an insect repellent
- Included in preparations for digestive and respiratory support
These uses are based on historical practices and are not indications for therapeutic use.
Fun fact
African marigold flowers are often added to chicken feed to enhance the colour of egg yolks and poultry skin due to their naturally high carotenoid content.
Part used
- Flowers (aerial parts)
Key constituents
- Carotenoids (including lutein and zeaxanthin)
- Polyphenols
- Flavonoids
Why lutein matters for eye health
Lutein is found in high concentrations in the retina, where it helps:
- Filter blue light
- Support visual function
- Maintain eye macula and retina health
- Provide antioxidant support
As an antioxidant, lutein helps reduce free radicals formed in the body and supports cellular health.
What does the research say?
Research into lutein has explored its role in maintaining eye health and visual function, particularly as we age.
Large nutritional studies, including the AREDS2 study, have investigated combinations of nutrients such as lutein and zeaxanthin in older adults.
Findings from observational and clinical research suggest:
- Higher dietary intake of lutein and zeaxanthin is associated with better eye health outcomes
- Lutein contributes to antioxidant protection in eye tissues
- Nutritional support may play a role in maintaining visual function over time
These findings reflect nutritional research and do not imply treatment or prevention of disease.
