Herbarium: Medicinal Plants as Information

Eclipta prostrata: The False Daisy

Eclipta prostrata is a medicinal plant found in the United States and in tropical and subtropical regions and is said to treat various ailments. Information about the plant can be found in the UCLA Herbarium, a related plant (Bahiopsis lanata) in the Mildred E. Mathias Botanical Garden, and from historical materia medica.

An Eclipta prostrata specimen was collected between a bike path and railroad tracks in west Los Angeles. It was identified by comparing the characteristics of the collected specimen to various texts and previous research such as field notebooks, the Jepson Manual, and specimens collected at other institutions. Furthermore, it was preserved carefully using the herbarium’s process of preservation that includes carefully and aesthetically placing the sample onto a special type of paper with glue. This is to preserve the specimen for later analysis.

Since Eclipta prostrata is not grown in the botanical garden at UCLA, a live Bahiopsis lanata specimen can offer information about Eclipta prostrata, given that both plants are from the Asteraceae family. Found in the California native plants bed, it grows elevated on a bed of concrete. Bahiopsis lanata natively grows in Baja California, similar to how Eclipta prostrata grows in Los Angeles. In addition to more arid regions, Eclipta prostrata grows in more tropical locales like India, Southeast Asia, China, and Brazil. Eclipta prostrata has also been found near streams across the United States, commonly found as a weed in warm areas. Though both Eclipta prostrata and Bahiopsis lanata grow low to the ground and have yellow flowers, Bahiopsis lanata has a clustered leaf pattern at its base and a tall shoot that ends in its flower. Eclipta prostrata, on the other hand, has leaves along its main stem with smaller branches rather than the shrub-like growth of Bahiopsis lanata.

Eclipta prostrata is said to treat various diseases but the major medicinal uses are for the treatment of gastrointestinal disorders like diarrhea and dysentery, respiratory illnesses like asthma, hair loss, fever, skin disorders, wounds, and liver disorders like jaundice. Practitioners in Brazil have used Eclipta prostrata as a remedy for snakebites. Eclipta prostrata has been used in Ayurvedic medicine in the Indian subcontinent, where the plant is commonly called Bhringraj. Chemicals responsible for the plant’s medicinal uses include “coumestan derivatives, steroidal and triterpenoid saponins, phenolic acids, flavonoids, and substituted thiophenes” (Timalsina & Devkota). The plant is prepared in several ways, mainly involving a tea, decoction, or extract of the leaves, roots, or the whole plant (Jahan et al.).
