- Used for centuries for its mild sedative properties
- Rich in plant compounds (polyphenols, flavonoids)

What is lemon verbena?
Lemon verbena, scientifically known as Aloysia citriodora (or Aloysia citrodora), is a small, woody shrub native to South America. It is now cultivated in many Mediterranean and temperate climates. Its elongated leaves emit a strong lemon scent that immediately distinguishes it from other plants in the Verbenaceae family.
This plant is often confused with common vervain (Verbena officinalis), a botanically distinct species with different properties. Lemon verbena is recognizable by its characteristic aroma, which is much stronger and fresher. Its small white or pale mauve flowers are grouped in elegant spikes.
It is primarily used as an infusion, dietary supplement, or essential oil. In cooking, its leaves flavor desserts, drinks, and savory dishes. It is easy to grow in pots, making it a popular balcony plant for herb enthusiasts. To learn when and how to harvest it at its best, consult our practical guide on harvesting lemon verbena.
Lemon verbena and sleep: what research says
The link between lemon verbena and sleep is one of the best documented among its traditional uses. Historically, several societies have relied on this plant for its mild sedative effects and its ability to aid sleep. Scientific research is beginning to explore these properties using rigorous methods.
A study published in reminds us thatAloysia citriodora has a long history of traditional use for sedation and the treatment of insomnia in various cultures [1]. This historical recognition provides a solid starting point for clinical research.
More recently, a randomized, double-blind clinical trial published in evaluated the effect of Aloysia citrodora extract supplementation on sleep quality in healthy subjects. These data remain preliminary, and further studies are needed to confirm the magnitude of this effect.

Plant compounds: what makes this plant interesting
Lemon verbena contains a variety of plant compounds, including polyphenols and flavonoids, which are being researched for their potential health effects. These molecules are found in many aromatic plants and have been associated with antioxidant and anti-inflammatory properties in laboratory models.
A study examined the polyphenols of lemon verbena and hibiscus in a randomized controlled trial of overweight subjects. Researchers observed that these polyphenols modulated certain appetite -related biomarkers [2] . These results are interesting but should be interpreted with caution.
The richness of phytochemical compounds in this plant is part of a broader research context on Mediterranean aromatic plants. These compounds likely contribute to all the properties attributed to the plant, even if the precise mechanisms remain to be elucidated for each use.
Relaxation and mild stress: a well-established traditional use
Lemon verbena is traditionally associated with managing mild stress and promoting relaxation. This use is widespread in Mediterranean and South American cultures, where an infusion of its leaves is consumed in the evening to encourage relaxation after a busy day.
This relaxing effect is often attributed to the combined action of its plant compounds on the nervous system. However, clinical data specific to this use remain limited. It is therefore prudent to speak of relaxation support rather than a treatment for stress or anxiety.
This plant fits naturally into an evening wellness routine, complementing other habits that promote mental calm: reducing screen time, slow breathing, and a peaceful environment. To learn more about the general effects of verbena, see our article on the effects of verbena.
Lemon verbena and digestion: what do we really know?
The digestive use of lemon verbena is one of the oldest recorded in herbal traditions. It is often recommended after meals to relieve bloating, mild intestinal spasms, and digestive discomfort. This use is shared by many cultures that cultivate it.
Its mild antispasmodic properties are generally attributed to its aromatic compounds and polyphenols. However, clinical studies specifically dedicated to the digestive effects of this plant remain scarce to date. The available data come mainly from traditional knowledge and preliminary observations.
In practice, an infusion of lemon verbena leaves after a meal is a simple and accessible approach. It can be part of a broader digestive support strategy, but it should not replace medical advice if symptoms persist. To learn more about the benefits of lemon verbena infusion, see our article on the benefits of lemon verbena infusion.
How to prepare a lemon verbena infusion
Infusion is the most common and accessible way to use lemon verbena. It allows you to benefit from the water-soluble compounds contained in the leaves, while enjoying its characteristic lemony aroma.
To prepare an infusion, follow the dosage and instructions provided by the manufacturer or recommended by a healthcare professional. Generally, dried or fresh leaves are steeped in hot water for a few minutes, then strained before drinking. The steeping time and quantity vary depending on the product and intended use.
- Use high-quality dried leaves, preferably organic
- Cover your cup during brewing to preserve the volatile aromatic compounds
- Ideally, consume it in the evening, before bedtime, if the goal is to promote sleep

- Always follow the manufacturer's or a healthcare professional's instructions
Lemon verbena can also be consumed as a dietary supplement (capsules, standardized extracts). In this case, carefully follow the manufacturer's or pharmacist's recommendations.
Lemon verbena vs. other plants for sleep
Lemon verbena isn't the only plant used to promote sleep. However, it stands out for its unique aromatic profile and versatility (sleep, digestion, relaxation). Here's a comparative overview with other commonly used plants:

Lemon verbena in cooking and aromatherapy
Beyond its medicinal uses, lemon verbena is a culinary herb prized for its intense lemony aroma. Its fresh or dried leaves flavor desserts, cold drinks, marinades, and certain fish or poultry dishes. Its delicate fragrance also makes it a decorative and aromatic plant for gardens and balconies.
In aromatherapy, lemon verbena essential oil is used for its relaxing properties and characteristic fragrance. However, it is considered potentially photosensitizing and irritating to sensitive skin; therefore, its use should be guided by professional advice. Never apply it undiluted to the skin without first diluting it in a carrier oil.
Growing this plant in a pot is easy, even for beginners. It thrives in sunny locations and well-drained soil. Its leaves can be harvested throughout the growing season. To maximize your harvest, our guide on when to harvest lemon verbena will give you all the practical tips you need.
Benefits on appetite and metabolism: preliminary data
An interesting avenue of research concerns the effect of lemon verbena polyphenols on certain appetite-related biomarkers. A randomized controlled trial published in investigated the combined effect of hibiscus and lemon verbena polyphenols in overweight subjects. The results suggest a modulation of biomarkers related to appetite regulation [2].
These data are preliminary and do not allow us to conclude that lemon verbena taken alone has a slimming or appetite-suppressing effect. The study involved a combination of plants, and it is impossible to attribute the observed effects solely to lemon verbena. Further research is needed to clarify these effects.

How to choose a quality lemon verbena-based product
The market for dietary supplements and herbal teas made with lemon verbena is vast. Product quality varies considerably depending on the origin of the plants, the drying and processing methods, and the quality controls applied by the manufacturer.
