Lemon verbena or lemon beebrush, ALOYSIA TRIPHYLLA = LIPPIA CITRIODORA = ALOYSIA CITRIODORA, VERBENACEAE, is a shrub native to temperate or subtropical areas of South America (Peru, Chile, Argentina, Paraguay).
It is quite common in the pre-Andean regions where it has several local appellations: cedron, hierba luisa or verbena de Indias.
It was introduced in southern Spain in the 17th century, and then spread to southern Europe, North Africa and the USA.
Lemon or fragrant verbena does not grow in cold or dry regions; it can reach 2 to 4 m high; the leaves, lanceolate with a marked apex and a smooth or slightly serrated margin, are whorled in groups of 2 to 4, most often 3 (hence the name triphylla).
The terminal inflorescence in fairly loose crown is made of bilabiate pink or lilac flowers of small size.
The fruit that does not always reach maturity is a drupe that contains two seeds.
When the weather is hot lemon verbena gives off a strong citrus odor; crumpled leaves also have this characteristic lemon scent.

CHEMICAL COMPOSITION AND PROPERTIES
LIPPIA CIRIODORA LEAVES
Lemon verbena leaves contain :
- flavonoids,
- phenol acids,
- about 0.25% yellow, lemon-scented essential oil, dominated by citral (35%), with limonene, linalool, terpineol, cineole and caryophyllene, other terpenoids are in small quantities.
The chemical composition of lippia citriodora essential oil is variable depending on the growing conditions but still dominated by citral.
Flavonoids and phenolic acids are antioxidants, scavengers of free radicals.
An experimental study shows that the infusion of lemon verbena mainly traps superoxide radicals and a little less the hydroxyl radicals
The terpenoids of the essential oil are: - bacteriostatic and bactericidal, antiviral and antifungal (active on candida albicans),
- stomachic, eupeptic,
- calming of the central nervous system (sedative),
A Japanese study reveals that the essential oils of Cymbopogon citratus (lemongrass) and Aloysia citriodora (lemon verbena) are bactericidal for Helicobacter pylori at a concentration of 0.01% and a pH between 4.0 and 5.0.
These two essential oils, chemically similar, both contain a lot of citral.
In addition Helicobacter pylori responsible for many gastric ulcers does not acquire resistance to these essential oils, while it tends to become resistant to many antibiotics.
The infusion of lippia citriodora (which contains both phenolic compounds and a few terpenoids): - facilitates digestion,
- is slightly sedative,
- has anti-inflammatory properties.
