The traditional use of Tagetes erecta L. (Asteraceae), commonly known as Cempasúchil, has been a cornerstone of Mesoamerican ethnobotany, revered in ceremonial and medicinal contexts. This study delves into the historical and ethnobotanical trajectory of T. erecta, tracing its journey from pre-conquest Mesoamerican uses to its current global recognition in pharmacological realms.
Originally endemic to Mexico, T. erecta was extensively used in rituals and healing practices associated with Tlaloc, the rain god. The Spanish conquest catalyzed a pivotal shift, recontextualizing this species as an ornamental entity in Europe, known variably as African marigold or African tansy. Linnaeus’ classification integrated this species into Western botanical nomenclature, broadening its recognition.
The discovery of lutein in T. erecta in the early 19th century marked a significant transition, illustrating the plant’s potential in phytotherapy, especially for macular health. Its inclusion in pharmacopeias and designation as Generally Recognized As Safe (GRAS) in the USA signify its dual role in traditional medicine and modern applications, including its economic impact in sectors like poultry feed due to its carotenoid richness.
This paper emphasizes the importance of ethnohistorical, pharmacological, and cultural perspectives in understanding the multifaceted roles of T. erecta. It underscores the need for sustainable conservation strategies to preserve traditional uses while fostering modern applications. The global dissemination of T. erecta, intertwined with cultural, historical, and scientific narratives, offers a unique case study in the broader field of ethnopharmacology, highlighting the dynamic interplay between traditional knowledge and modern scientific inquiry.
