Common Name: Vine Mormon-tea

General Information

Ephedra pedunculata is a climing, evergreen shrub with very small, scale-like leaves and green, wiry stems where most of the photosynthesis takes place; it can grow around 6 - 7 metres tall, the stems sometimes scrambling over the ground if no support is available[].
The plant is harvested from the wild for local use as a medicine.
The range of Ephedra pedunculata is somewhat restricted, but not small enough to meet the threshold for a threatened category.Due to a lack of any known major threats, 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
Requires a sunny position in a freely-draining soil. It grows well in dry soils and is very drought tolerant once established[].
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.

Edible Uses

The red fruit is fleshy[].

Medicinal

The leaves and branches are used to treat problems involing the liver, prostate and uterus; cysts in the uterus; kidney and urinary tract infections; high blood pressure, and varices[].

The plant, part not specified, is valued in Mexico as a remedy against pleurisy and pneumonia[, ].

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[, ].

Other Uses

None known

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.
