Physical Characteristics
An evergreen shrub growing to 1.8m. It is hardy to zone 9. It is in leaf all year. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required).
The plant not is self-fertile.
We rate it 2/5 for edibility and
3/5 for medicinal use.
The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil.
The plant prefers acid, neutral and basic (alkaline) soils.
It cannot grow in the shade.
It requires dry or moist soil and can tolerate drought.
Habitats and Possible Locations
Cultivated Beds.Edible Uses
Fruit
Seed Tea.
Fruit - raw. A sweet flavour.
Seed - cooked. A bitter flavour, it is roasted and ground into a powder and
used to make a bread or mush[183].
A delicious tea is made by steeping the green or dried twigs in boiling
water[183, 257]. The flavour is said to be improved if the stems are roasted
first[183].
Medicinal Uses
Disclaimer
Blood purifier Diuretic Kidney Poultice Stomachic Tonic VD.
This plant has a wide reputation as a cure for syphilis[216]. A strong
decoction of the stems was drunk and a poultice of the pulverized or boiled
stems applied to the sores[257].
The stems are blood purifier, diuretic and tonic[257]. An infusion has been
used in the treatment of coughs and colds, anaemia, rheumatism, stomach
ulcers and other disorders, kidney problems[257]. The dried, powdered stems
are used as a dressing on sores and burns[257].
The stems of most members of this genus contain the alkaloid ephedrine and
are valuable in the treatment of asthma and many other complaints of the
respiratory system[K]. The whole plant can be used at much lower
concentrations than the isolated constituents - unlike using the isolated
ephedrine, using the whole plant rarely gives rise to side-effects[254].
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
they can also be eaten raw[K]. The young stems are best if eating them raw,
though older stems can be used if a tea is made[K]. The stems can be
harvested at any time of the year and are dried for later use[238].
Other Uses
Dye.
The twigs, boiled with alum, produce a light tan dye[257].
Cultivation details
Requires a well-drained loamy soil and a sunny position[11].
Established plants are drought resistant and are also lime tolerant[200].
This species is not very hardy in Britain, it succeeds well in a cold
greenhouse but is often killed outdoors by a combination of cold and wet
conditions[200].
Dioecious, male and female plants must be grown if fruit and seed is
required.
Propagation
Seed - best sown as soon as it is ripe in the autumn in a
greenhouse[200]. It can also be sown in spring in a greenhouse in a sandy
compost[K]. 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[K].
Division in spring or autumn[238].
