What is Tagetes?
Tagetes is another one of those plants that can cause confusion. According to Brittanica.com, all plants of the genus tagetes are marigolds.  However, they should not be confused with "true" marigold (Calendula officinalis).
There are around 50 plants in this genus. While they originally hail from Mexico and South America, they are now found growing wild in Africa, Asia, Europe, as well as North and Central America.
The fast-growing plants feature beautiful flowers in hues of red, orange, and yellow. T. minuta, also known as T. glanduliflora, has daisy-like flowers that are either orange or yellow.
Two other types of tagetes that share similar qualities and produce essential oil are the African/Aztec marigold (Tagates erecta), and the French marigold, (Tagetes patula).
T. minuta oil should be yellow to orange in color. It blends well with citrus oils like bergamot (Citrus bergamia) and grapefruit (Citrus paradisi). It also pairs well with clary sage (Salvia sclarea), lavender (Lavandula angustifolia), and both German and Roman chamomile.
Tagetes oil is a photosensitizer, so it should not be used on the skin before going into the sun or using a tanning bed. It has been known to cause dermatitis and may cause irritation in people with sensitive skin, so a skin patch test is highly advisable.
This oil should be used in moderation. Do not use while pregnant or nursing.

Tagetes Essential Oil Research, Facts, and Studies
Anti-inflammatory and Antioxidant
In 2014, researchers found that tagetes could help diminish immune responses. It has anti-inflammatory properties and also shows protective qualities against oxidative damage.
These findings mean that the oil could be a practical and natural antioxidant. 
In a Journal of Ethnopharmacology article published in 2017, researchers wrote about the future prospect of tagetes oil as a potential antimicrobial agent.
The team searched through studies and papers over five databases to gather information on tagetes and its applications. The years checked were from 1997-2015 and after careful examination of the results, they narrowed their search down to 10 relevant studies.
After carefully analyzing the data, they concluded that further use of tagetes as a novel antimicrobial should continue to be successful in both animal and clinical studies.
While more evidence is required, they believe that tagetes could be not only an affordable and effective alternative treatment for infectious diseases, but a safe one as well. 
Nutritional and Pharmaceutical Applications
In 2018, researchers set out to analyze the chemical composition, fatty acid, and antioxidant profile of T. minuta growing wild in Iran. Their findings were published in the March Advanced Pharmaceutical Bulletin.
The essential oil was studied by gas chromatography and mass spectrometry (GCMS). They found over 50% were monoterpenoid fractions. They also discovered that fatty acids were a significant component and the oil had effective antioxidant capabilities.
The researchers concluded that tagetes essential oil could be useful in applications in both nutritional and pharmaceutical markets. 
While tagetes is one of the lesser-known oils to many home enthusiasts, aromatherapists and researchers both agree that the volatile oils of these plants could prove to be beneficial in medicinal uses and other applications.
As there are three different plants that are commercially sold as tagetes oil, always check the botanical name to make sure you have the correct one. If you end up with something other than T. minuta that was discussed here, be sure to do your research before attempting to use it.
