General Information

Ephedra alata is an erect, robust, xerophytic shrub forming much-branched, dense clumps[]. It has very small, scale-like leaves and green, wiry stems where most of the photosynthesis takes place; it can grow up to 100cm tall[, ]
The plant is harvested from the wild for local use as a medicine and source of materials
Ephedra alata is wide ranging and reported as common where found. The plant is classified as 'Least Concern' in the IUCN Red List of Threatened Species(2011)[].

Known Hazards

Many species in this genus contain phenylethylamine alkaloids (e.g. ephedrine, pseudoephedrine). These compounds have stimulant properties and are effective medications in the treatment of a number of conditions. However, they do also have potential side effects and are contraindicated in a number of conditions including anxiety, anorexia, bulimia, diabetes, glaucoma, hypertension, thyrotoxicosis[].

Cultivation Details

Ephedra species are mainly temperate to subtropical plants, native to arid and semi-arid regions and are also found in seasonally dry habitats such as Mediterranean climates. They are often found at moderate to high elevations, especially when they occur in tropical regions.
The plant tolerates dry soils and saline soil[]. Established plants are drought tolerant[].
A dioecious species, both male and female forms need to be grown if fruit and seed are required.
Plants require a good summer in order to fully ripen their wood - this will encourage good flowering and fruiting the following summer.

Medicinal

The stem is used as a deobstruent; to treat circulatory system disorders; to treat kidney disorders; as a stimulant, to treat bronchi disorders; to relieve asthma; and is also used for the eyes[].
The plant (part not specified) is used to treat digestive system disorders[].

Ephedra species, especially those found in Asia, have a long history of medicinal use, particularly in the treatment of respiratory conditions such as asthma, hay fever, catarrh and coughs. They are also considered to be antisyphilitic, antipyretic and circulatory stimulants. The main active substances are alkaloids, particularly ephedrine and the closely related pseudoephedrine, though many other alkaloids can be present.
Ephedrine and pseudoephedrine are found mainly in the Asian species; those species in the Americas generally have much lower or zero levels, though they do contaim various other alkaloids. These American species often have a high reputation as a refreshing tonic tea that promotes kidney and urinary tract health[, ].
The isolated Ephedrine is often used medicinally as a central nervous system (CNS) stimulant to prevent low blood pressure during anesthesia, and to treat conditions including asthma, narcolepsy, and obesity. However, the isolated compound can have various side effects and it has been shown that the whole plant can be used at much lower concentrations than the isolated alkaloid and rarely gives rise to side-effects[].

Ephedra does not cure asthma but in many cases it is very effective in treating the symptoms and thus making life somewhat easier for the sufferer. The stems can be used fresh or dried and are usually made into a tea, though the young stems can also be eaten raw[]. The stems can be harvested at any time of the year and are dried for later use[].

Agroforestry Uses:

The rhizomes can attain a length of several metres and form efficient sand binders. The plant is used to control erosion in sandy areas[].

Other Uses

Fibres from the stems are used to make cord, string or twine[].

The plants are a source of tannins that can be used as dyestuffss. They are obtained by grinding the leaves, roots, peel or bark then boiling in water[]..

Propagation

Seed - best sown as soon as it is ripe in the autumn in a greenhouse[]. It can also be sown in spring in a greenhouse in a sandy compost[]. Prick out the seedlings into individual pots as soon as they are large enough to handle and grow them on for at least their first winter in a greenhouse. Plant out in the spring or early summer after the last expected frosts and give some protection in their first winter[].
Division in spring or autumn[].
Layering.
