Physical Characteristics

An evergreen shrub growing to 1m by 1m . It is hardy to zone 6. It is in leaf all year, in flower in July. 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 3/5 for edibility and 4/5 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.

Medicinal Uses

Disclaimer

Antiasthmatic Antispasmodic Antitussive Antiviral Diaphoretic Diuretic Febrifuge Miscellany Nervine Tonic Vasoconstrictor.

Members of this genus contain various medicinally active alkaloids (but notably ephedrine) and they are widely used in preparations for the treatment of asthma and catarrh[238]. 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]. The plant also has antiviral effects, particularly against influenza[238].
The stems are a pungent, bitter, warm herb that dilates the bronchial vessels whilst stimulating the heart and central nervous system[238]. The stems are also antitussive, diuretic, diaphoretic, febrifuge, hypertensive, nervine, tonic and vasoconstrictor[4, 21, 174, 238]. They are used internally in the treatment of asthma, hay fever and allergic complaints[238]. They are also combined with a number of other herbs and used in treating a wide range of complaints238]. This herb should be used with great caution, preferably under the supervision of a qualified practitioner[238]. It should not be prescribed to patients who are taking monoamine oxidase inhibitors, or suffering from high blood pressure, hyperthyroidism or glaucoma[238]. Ephedrine is seen as a performance-boosting herb and, as such, is a forbidden substance in many sporting events such as athletics[K].
The stems can be harvested at any time of the year and are dried for later use[238].

Other Uses

Ground cover.

Plants can be used for ground cover, spaced about 60cm apart each way[208].

Cultivation details

Requires a well-drained loamy soil and a sunny position[11]. Established plants are drought resistant and are also lime tolerant[200].
Plants are hardy to at least -15° c[200].
This species does not flower or fruit well in Britain[11].
Dioecious. Male and female plants must be grown if 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].
Layering.
