Etymology –
The name of the genus Ephedra derives from the Ancient Greek ἐφέδρα (ephedra), a term used to designate a plant with an appearance similar to that of horsetails. The word is connected with epí, “above”, and hédra, “seat” or “base”, probably referring to the arrangement of the cones or reproductive structures on the branches. The etymology therefore primarily evokes the characteristic form of the plant, whose green, jointed stems, almost devoid of leaves, do indeed resemble those of horsetails at first sight. The ancient Greek name was already known to Pliny and was subsequently adopted into botanical nomenclature.
The specific epithet fragilis, from the Latin for “fragile”, “weak”, or “easily broken”, describes a readily recognizable characteristic of the shrub: its branches, especially when dry, tend to break relatively easily. The complete scientific name is therefore Ephedra fragilis Desf., a species described by the French botanist René Louiche Desfontaines in 1799.

Geographical Distribution and Habitat –
Ephedra fragilis is a species characteristic of the western and central Mediterranean region and Macaronesia, with a range extending across North Africa and southern Europe. It occurs, in particular, in Algeria, Morocco, Tunisia, Libya, and Western Sahara and, on the European side, in Spain, Portugal, Italy, and the Balearic Islands; it is also recorded in the Canary Islands and Madeira. In Italy, its distribution is concentrated mainly in the southern and insular regions, where it is associated with warmer and drier Mediterranean environments.
It is a characteristic plant of open, dry, and strongly sun-exposed habitats, often occurring near the sea. It grows on rocky slopes, embankments, limestone or gypsum soils, and poor substrates, including sandy and somewhat saline soils. Its presence along coastal elevations is consistent with the original description of the species, which referred to plants collected from mountains located near the coast. It is therefore a component of Mediterranean scrubland and shrub vegetation, capable of tolerating drought conditions and intense exposure to sunlight.
The species belongs to a group of gymnosperms that is particularly interesting from an ecological perspective, as many Ephedra species are adapted to arid and semi-arid climates. E. fragilis, in particular, is classified by the IUCN as Least Concern (LC), meaning “least concern”, at the global level.

Description –
Ephedra fragilis is an evergreen, highly branched shrub, generally one to two metres tall, with a habit that may be erect or slightly spreading. Its appearance is unusual and easily recognizable: the numerous green branches are slender, cylindrical, jointed, and marked by closely spaced nodes, while the true leaves are extremely reduced. Photosynthesis is in fact carried out mainly by the green stems, a characteristic that helps reduce water loss in hot and arid environments.
The leaves, opposite and scale-like, are only a few millimetres long and often form small sheaths around the nodes. The overall appearance of the plant therefore resembles that of a horsetail or, from a certain distance, that of a small broom-like shrub. The extensive branching and the fragility of the dry branches help explain both its bushy appearance and the specific epithet fragilis.
Like other Ephedra species, it is a dioecious plant: male and female individuals are separate. The male reproductive structures occur in small, globose groups, while the female structures develop into formations with bracts that, when mature, may take on reddish or yellowish hues and surround the seeds. Fruiting thus contributes to making the plant more easily identifiable during the reproductive season.
From a taxonomic perspective, the species belongs to the family Ephedraceae and the order Ephedrales, within the gymnosperms. The taxonomy currently adopted by Plants of the World Online recognizes two subspecies: Ephedra fragilis subsp. fragilis, distributed mainly in the western Mediterranean and Macaronesia, and E. fragilis subsp. cossonii, native to northwestern Africa.
An aspect of particular interest is its chemical composition. The aerial parts of the species contain ephedrine- and pseudoephedrine-type alkaloids, although their concentration can vary considerably depending on the plant part, population, and environmental conditions. Phytochemical analyses have confirmed the presence of these compounds in E. fragilis and have shown, in some samples, a significant predominance of ephedrine.

Cultivation –
In cultivation, Ephedra fragilis is particularly suitable for Mediterranean, rock, and xeric gardens, where it can be appreciated for the distinctive appearance of its green branches and its ability to survive under conditions of limited water availability. The ecological requirements of the species suggest a position in full sun and a very well-drained soil, preferably poor or moderately fertile, including calcareous and sandy soils.
Heavy substrates prone to waterlogging should be avoided, as these conditions differ markedly from those of its natural habitats. Once well established, the plant has good drought tolerance and generally requires limited irrigation. Its highly branched habit can be left to develop freely in order to preserve the shrub’s natural appearance, or it can be slightly controlled through targeted pruning.
Ornamental cultivation should not, however, be confused with cultivation intended for herbal use. The presence of pharmacologically active alkaloids makes it inadvisable to collect and prepare branches from plants grown in the garden on one’s own, since the appearance of the plant alone does not make it possible to determine the concentration of active substances present in the plant material.

Uses and Traditions –
The genus Ephedra has a long ethnobotanical history, particularly in Asia. It is important, however, to distinguish the general history of the genus from that specifically associated with Ephedra fragilis. The well-known herbal drug known as Ephedrae herba or Ma Huang consists mainly of Asian species such as E. sinica, E. intermedia, and E. equisetina and should not automatically be identified with E. fragilis.
Throughout history, various Ephedra species have been used in different traditional medicines, particularly for respiratory disorders, colds, coughs, nasal congestion, and asthma. The reason for this interest is related to ephedrine alkaloids, which have stimulant and sympathomimetic activity. The medicinal tradition surrounding Ephedra is therefore ancient, but the chemical composition varies among species, making it potentially unsafe to automatically transfer uses attributed to other Ephedra species to E. fragilis.
Ephedra fragilis has also been documented in traditional North African medicine. An ethnobotanical review published in 2024 recorded the use of the species in Morocco, where the aerial parts and leafy stems are traditionally associated mainly with hair care and the treatment of diabetes. In other Moroccan areas, the species has also been reported in folk medicine for various conditions to which different therapeutic meanings have been attributed. These data document a traditional practice but do not, in themselves, constitute evidence of the clinical efficacy of the treatments concerned.
Modern interest in Ephedra, on the other hand, has been strongly influenced by the use of extracts as weight-loss and stimulant products. In the United States, supplements containing ephedra alkaloids were also marketed for weight loss and improved athletic performance; in 2004, the Food and Drug Administration banned their sale as dietary supplements because of the risks associated with ephedrine alkaloids. Available reviews indicate that the short-term effects on weight loss were modest, whereas cardiovascular and neurological risks could be serious.

Preparation and Uses –
In the ethnobotanical traditions documented in Morocco, Ephedra fragilis has been used mainly in the form of a decoction prepared from the aerial parts or leafy stems; depending on the locality, sources report both its use for hair care and its traditional consumption in connection with diabetes. More generally, the history of Ephedra includes the use of infusions and decoctions prepared from the green parts, while some traditions have also made use of other parts of the plant.
For E. fragilis, however, the presence of ephedrine alkaloids requires a clear distinction between ethnobotanical description and recommendations for use. It is therefore not advisable to provide a home recipe, dosages, or instructions for consuming the plant: the amounts of ephedrine and pseudoephedrine can vary considerably, and a homemade preparation does not allow their concentration to be controlled. Phytochemical studies have indeed confirmed the presence of these alkaloids in the species, with marked differences even among flowers, seeds, and branches.
The reason for caution is important. Ephedra alkaloids can cause increased blood pressure, tachycardia, and other cardiovascular effects, as well as more serious events such as heart attack, stroke, and seizures. The risk may increase when combined with other stimulants, such as caffeine, and their use is considered particularly problematic in children and during pregnancy and breastfeeding. For these reasons, U.S. health authorities have banned dietary supplements containing ephedra alkaloids, and major health sources advise against the unsupervised use of ephedra-based products.
It is therefore more appropriate today to regard Ephedra fragilis primarily as an interesting species of the Mediterranean flora and as a subject of ethnobotanical and phytochemical research, rather than as a plant to be prepared and consumed independently. Its traditional history remains significant because it documents the relationship between Mediterranean populations and wild medicinal plants; however, modern knowledge of its chemical composition makes it necessary to clearly distinguish the historical and cultural value of traditional uses from the safety of any potential contemporary application.
