Plains Coreopsis (Coreopsis tinctoria) is an annual wildflower native to North America, recognized for its vibrant yellow and red blooms. This plant has a long history among indigenous peoples, who used it for various traditional practices. This article explores these historical uses, modern scientific investigations, and safety considerations.
Traditional Medicinal Uses of Plains Coreopsis
Native American tribes traditionally utilized Plains Coreopsis for various purposes. Infusions from the plant’s dried tops or roots were consumed as a tea for diarrhea and abdominal discomfort. The whole plant was also boiled to create a drink to address internal pains and bleeding. Some traditional practices involved using a tea from the dried tops to strengthen the blood or preparing a root tea as an emetic.
Historical accounts also suggest its use as a disinfectant and for sexual infections. In some communities, the flowers were boiled to create a beverage, sometimes serving as a coffee substitute. The Zuni people traditionally used an infusion of the whole plant, excluding the root, for family planning. Traditional Chinese medicine has also incorporated Coreopsis species, including Plains Coreopsis, for conditions such as high blood pressure, insomnia, and hyperlipidemia.
Plains Coreopsis: A Scientific Perspective
Modern scientific inquiry investigates the chemical composition and properties of Plains Coreopsis. Researchers have identified over 100 chemical constituents, with flavonoids being prominent. These include chalcones, flavanones, and flavonols, alongside polyacetylenes, polysaccharides, and volatile oils.
Laboratory and animal studies explore various potential biological activities of Plains Coreopsis extracts. These investigations suggest antioxidant, anti-inflammatory, and neuroprotective effects. Research also indicates potential antidiabetic, anti-cardiovascular disease, and hepatoprotective attributes. However, comprehensive human clinical trials validating these observed properties are generally limited.
Safety Considerations and Precautions
Plains Coreopsis belongs to the Asteraceae family, which includes plants like ragweed and marigold. Individuals sensitive to plants in this family may experience allergic reactions, such as skin irritation, contact dermatitis, hay fever, or asthma. These reactions are sometimes attributed to sesquiterpene lactones found in Asteraceae species.
While traditional uses involved internal consumption, scientific research on the safety of ingesting Plains Coreopsis is not extensive. Therefore, caution is advised regarding internal use. Consult a qualified healthcare professional before using any plant for medicinal purposes, especially for pregnant or breastfeeding individuals, children, or anyone with pre-existing medical conditions or taking other medications.
