The stems can be brewed into tea, but the tea should be used in moderation. Seeds of this species are the least reassuring in the group and are better treated as doubtful or unsuitable for regular food use. In practical terms, southwestern ephedra is a beverage plant, not a nut crop [2-3]. Edible Uses & Rating: As a tea plant, southwestern ephedra ranks as fair to moderate. As a seed food, it ranks low. The stems are useful, but the seeds are too acrid and uncertain to recommend as a dependable food [2-3]. Taste, Processing & Kitchen Notes: Tea made from young green stems is the best use. Older wood is weaker and blander. The seeds can look promising because they are small, brown, and nut-like, but they are usually harsh, acrid, and disappointing. Even roasting only partly improves them, so this is not a species to seek out for seeds [2-3]. Seasonality (Phenology): Like other southwestern ephedras, this species flowers in spring into early summer. Tea stems can be clipped in multiple seasons, though fresh green growth generally makes the best beverage. Seeds mature later and can fall quickly once ripe, so harvest timing matters if they are being studied at all. Safety & Cautions (Food Use): Tea should be consumed only in moderation because prolonged or heavy use of ephedra may affect the nervous system. The seeds should be approached with great caution. Sharp stem tips can also make harvest uncomfortable. This is a plant to know well, but not one to overuse [2-3]. Harvest & Processing Workflow: Clip young green stems with scissors; avoid old or infested material; use fresh, dried, or lightly roasted twigs for tea. If seeds are collected, a tarp and stick can help knock them free, but from a practical standpoint, the stems are much more worthwhile than the seeds [2-3]. Cultivar/Selection Notes: There are no food cultivars. The best collection material comes from healthy, green, uninfested shrubs growing in a clean habitat. Look-Alikes & Confusion Risks: It resembles other southwestern ephedras, but the genus as a whole is distinctive enough that confusion with unrelated shrubs is uncommon. The main identification challenge is distinguishing one ephedra species from another, rather than separating ephedra from non-ephedra plants [2-3]. Traditional/Indigenous Use Summary: Southwestern ephedra belongs to the broader Southwestern tradition of ephedra tea use, where these shrubs were valued primarily as medicinal or invigorating beverage plants rather than as staple foods [2-3].

Ephedra aspera, commonly known as canatilla or popotillo, has a history of use in traditional Mexican medicine to treat pneumonia, kidney failure, and venereal diseases. It has also been historically employed as a diuretic and to alleviate respiratory issues such as asthma and coughs. (National Institutes of Health.gov) Traditional Medicinal Uses: Ephedra aspera is utilized in various ways by different indigenous groups, primarily through infusions (teas) of the whole plant, stalks, or roots. Respiratory Illnesses: Used as a remedy for pneumonia and as an antitussive (cough suppressant). Kidney Health: Reported to help with kidney failure and Bright's disease (acute or chronic nephritis). Venereal Diseases: Traditionally used to treat syphilis and gonorrhea, sometimes applied directly as an ointment or ingested as an infusion. Other Uses: Historically cited for treating headaches, dyspepsia (indigestion), and hay fever. Important Safety Warning: While Ephedra aspera is used traditionally, it belongs to the genus Ephedra, which contains active compounds such as ephedrine. FDA Ban: The U.S. Food and Drug Administration (FDA) banned dietary supplements containing ephedrine alkaloids in 2004 due to risks of serious adverse effects, including heart attack, stroke, and death. Species Variability: Alkaloid content varies significantly among species. While Asian species (E. sinica) are high in stimulants, American species often contain lower levels, but still pose risks if misused.

A wiry, open shrub that is more botanically interesting than lush or ornamental. In desert gardens, it works best in native or restoration-style planting. Ecology & Wildlife: It adds cover and structure to dry shrublands and contributes to the evergreen framework of arid habitats. The aerial parts of this species are grazed by animals. The stems are used for their tannins, which are used as dyes [2-6].
