Thelesperma is a genus of North American and South American plants in the cosmos tribe within the sunflower family. [2] [3] [4] Greenthread is a common name for plants in this genus. [5]
Members of the genus are used by a number of the southwestern Native American peoples as an herbal tea; as such, it is sometimes called "Indian tea," "Native American tea," "Native tea," or the name is referenced to the local tribe where the tea was harvested such as "Apache tea," Pueblo tea," " Navajo tea," " Hopi tea," etc. T. megapotamicum contains luteolin. [6] It also appears that many of the species contain a very similar chromatographic profile, and thus may contain very similar profiles of flavenoids. [7] The genus is closely related to parts of Coreopsis and to certain North American Bidens species (including Bidens coronata and Bidens comosa). [8]
