Lemon essential oil is particularly appreciated for its many traditional properties.
According to specialised aromatherapy literature, it is known for:

• Refreshing and invigorating properties
• Air-purifying properties
• General toning action
• Astringent and cleansing effect
• Stimulation of mental energy

Traditional uses

Aromatherapy

Lemon essential oil is traditionally diffused to cleanse the air and bring a fresh, energising and positive atmosphere. It is ideal during periods of tiredness or lack of concentration.

Cosmetics and natural care

It is known for its astringent and purifying properties, which are particularly useful in care for oily or combination skin. It is also found in shampoos and lotions to rebalance oily scalps.

Household care

Thanks to its fresh, lemony fragrance, it is widely used in natural household products (deodorising sprays, multi-purpose cleaners, homemade laundry detergents) for its cleansing and deodorising power.

Well-being and relaxation

Emotionally, diffusing Lemon helps to clear the mind, stimulate concentration and encourage a good mood.

Other possible uses

In cooking, Lemon essence is sometimes used to flavour dishes or desserts, in tiny, highly diluted amounts, only if the oil is 100% pure and certified food-grade.
In perfumery, its citrus notes bring freshness and vitality to compositions.

Uses

Diffusion

A few drops in a diffuser are enough to freshen the air and create a fresh, energising atmosphere.

• Do not exceed 15 to 30 minutes per session.

Skin application

Always dilute Lemon essential oil in a vegetable oil.

• Recommended dilution: 10% (1 ml of essential oil for 9 ml of vegetable oil).
⚠️ Photosensitising: avoid any exposure to sun or UV within 12 hours of applying to the skin.

Inhalation

As a dry inhalation (1 drop on a tissue) or in an aromatic bath diluted in a dispersing base, it offers a refreshing, stimulating effect.

Synergies

Lemon essential oil blends particularly well with other essential oils to enhance its benefits and broaden its uses:

• Peppermint: a tonic, refreshing blend
• True Lavender: balance in relaxing and cleansing blends
• Sweet Orange: a joyful, sparkling atmosphere
• Grapefruit: body-contouring care and mood-lifting

⚠️ Precaution: respect the appropriate dosages and avoid sun exposure after applying to the skin.

Essential oils are powerful active ingredients that should be used with caution.

The use of Lemon essential oil is not recommended for:

• Pregnant and breastfeeding women (unless advised by a doctor)
• Children under 6
• People with a history of respiratory or skin allergies

Specific precautions

• Photosensitising: avoid any sun exposure after application.
• Always dilute before applying to the skin (risk of irritation).
• Keep the bottle tightly closed, away from heat and light, as the oil oxidises quickly.

A well-stored oil keeps its properties for around 2 to 3 years.

The plant

Lemon essential oil comes from Citrus limonum, a small fruit tree of the Rutaceae family.

Native to India and China, the lemon tree is now widely grown in the Mediterranean basin (Italy, Spain) and in Argentina.
Medium-sized (3 to 6 metres), it has evergreen foliage and fragrant white flowers, and bears yellow fruits rich in aromatic essence contained in the zest.

The essential oil is obtained by cold-pressing the zest, a method that preserves its delicate volatile molecules.

Its tangy, fresh and sparkling fragrance makes it an essential oil in aromatherapy, cosmetics and natural perfumery.

Anecdotes & History

Grown for thousands of years in India and China, lemon is known as a precious fruit, used both for its purifying virtues and its invigorating fragrance.

Introduced to the Mediterranean by the Arabs, it quickly became an essential ingredient in traditional health and well-being practices.

As early as Antiquity, it was believed to purify the air and protect people during great epidemics; its tangy fragrance was also used to perfume and freshen living spaces.

A universal symbol of vitality, purification and renewal, lemon is still associated today with natural cleansing rituals, boosting energy and clarity of mind.

Physical and olfactory characteristics

Lemon essential oil is characterised by:
• Appearance: clear, fluid liquid
• Colour: pale yellow to light green
• Scent: fresh, lively, tangy, typical of lemon zest
• Texture: light, highly volatile

Its fragrance is known for bringing an immediate feeling of vitality and freshness.

Biochemical composition

The richness of Lemon essential oil lies in its monoterpene content.
Main active constituents:

• Limonene (up to 70%)
• β-pinene
• γ-terpinene
• Sabinene
• Citral (in smaller proportion)

These molecules explain its refreshing, purifying and stimulating properties.
