The stem and roots are quite rich in stachyose. Aerial parts gave lupeol, beta-sitosterol, ursolic acid, aucubin and artemetin.The herb is credited with weak parasympathomimetic activity. Verbenalin exhibited mild purgative activity in animal studies. Emetic in high doses.Vervain tea decreased absorption of non-heme iron by 59% in human subjects. (Sharon M.

GENERAL DESCRIPTION: An attractive, tall, evergreen tree with a smooth dimpled bark, blotched in grey, cream and pink, cultivated as an ornamental. The trunk grows fast, straight and to considerable height, and is used for timber. The young leaves are oval, the mature leaves narrow and tapering.
DISTRIBUTION: Native to Australia; cultivated mainly in Brazil and China.
OTHER SPECIES: There are numerous other species of eucalyptus – see entry on eucalyptus blue gum. See also Botanical Classification section.
HERBAL/FOLK TRADITION: Used traditionally for perfuming the linen cupboard by enclosing the dried leaves in a small cloth sachet. During the last century it was regarded as a good insect repellent, especially for cockroaches and silverfish.
ACTIONS: Antiseptic, antiviral, bactericidal, deodorant, expectorant, fungicidal, insecticide.
EXTRACTION: Essential oil by steam distillation from the leaves and twigs.
CHARACTERISTICS: A colourless or pale yellow mobile liquid with a strong, fresh, citronella-like odour and sweet balsamic undertone.

SAFETY DATA: Non-toxic, non-irritant, possible sensitization in some individuals. Eucalyptus oil is toxic when taken internally, see Eucalyptus blue gum entry.
AROMATHERAPY/HOME: USE
Skin Care: Athlete’s foot and other fungal infections (e.g. candida), cuts, dandruff, herpes, insect repellent, scabs, sores, wounds.
Respiratory System: Asthma, laryngitis, sore throat.
Immune System: Colds, fevers, infectious skin conditions such as chickenpox, infectious disease. ‘The essential oil contained in the leaves appears to have bacteriostatic activity towards Staphylococcus aureus; this is due to synergism between the citronellol and citronellal present in the oil’..
OTHER USES: Used as a fragrance component (in place of E. globulus) in soaps, detergents and perfumes; also used in room sprays and insect repellents Employed for the isolation of natural citronellal.... lemon-scented
FAMILY: Verbenaceae
SYNONYMS: A. citriodora, Verbena triphylla, Lippia citriodora, L. triphylla, verbena, herb Louisa.
GENERAL DESCRIPTION: A handsome deciduous perennial shrub up to 5 metres high with a woody stem, very fragrant, delicate, pale green, lanceolate leaves arranged in threes, and small, pale purple flowers. Often grown as an ornamental bush in gardens.
DISTRIBUTION: Native of Chile and Argentina; cultivated (and found semi-wild) in the Mediterranean region – France, Tunisia, Algeria – as well as Kenya and China. The oil is mainly produced in southern France and North Africa.
OTHER SPECIES: Botanically related to the oregano family – see Botanical Classification section. Not to be mistaken for the so-called ‘Spanish verbena’ or ‘verbena’ oil (Spanish) (Thymus hiamalis), nor confused with the herb ‘vervain’ (Verbena officinalis). This is further confused since the French name for verbena is verveine (Verveine citronelle, Verveine odorante).
HERBAL/FOLK TRADITION: ‘The uses of lemon verbena are similar to those of mint, orange flowers and melissa.’. It is indicated especially in nervous conditions which manifest as digestive complaints. The dried leaves are still used as a popular household tea especially on the Continent, both as a refreshing, uplifting ‘pick-me-up’ and to help restore the liver after a hang-over.
ACTIONS: Antiseptic, antispasmodic, carminative, detoxifying, digestive, febrifuge, hepatobiliary stimulant, sedative (nervous), stomachic.
EXTRACTION: Essential oil by steam distillation from the freshly harvested herb.
CHARACTERISTICS: A pale olive or yellow mobile liquid with a sweet, fresh, lemony, fruity-floral fragrance. It blends well with neroli, palmarosa, olibanum, Tolu balsam, elemi, lemon and other citrus oils.
PRINCIPAL CONSTITUENTS: Citral (30–35 per cent), nerol and geraniol, among others.
SAFETY DATA: Possible sensitization; phototoxicity due to high citral levels. Other safety data is unavailable at present – however, true verbena oil is virtually non-existent. Most so-called ‘verbena oil’ is either from the Spanish verbena (an inferior oil), or a mix of lemongrass, lemon, citronella, etc.
AROMATHERAPY/HOME: USE
Digestive system: Cramps, indigestion, liver congestion.
Nervous system: Anxiety, insomnia, nervous tension and stress-related conditions.
